This is a summary of responses to my question about Uninterruptible Power
Supplies for Sun computer systems.

###########################################################################
ORIGINAL QUESTION:

This is a slightly off center request, please forgive.

Summer thunderstorms are nearly upon us and our uninterruptible power
supplies (UPS) are down! We've had difficulty locating an UPS manufacturer
that will return our calls. We've also had difficulty even locating any
UPS manufacturers. (Don't they advertise?)

Our current dead UPS are manufactured by a company that is dead also.

Could someone point us to a good UPS company, please.

We need both 110 and 220V UPS for our Sun4/280, 4/390 systems.

We've become addicted to having a constant supply of electrons :-)

MinuteMan systems (sold thru places like ComputerLand) makes a
nice line of products for small systems (under 1KVA).

BEST products makes a large line of power conditioners, but
I don't have an address on them - someone borrowed my file
folder on power conditioning :-(

I presume you aren't looking for Rotary Motor/Generator type
boxes to handle an entire building. Those vendors also exist,
and I can dig up a couple for you if needed.

P.S. Minuteman is the only thing I've used personally. It
worked great for my Mac, back when I had one.

I (i'm biased, remember) like the Best ones, they are Ferroresonant
and very good at lightning rejection as well as good for UNIX.
They run off of a Microprocessor that talks ASCII and can even shut
down the system. They provide a UNIX task to monitor the UPS and report
on problems. Sizes available from 300w to 15kw. Price is mid-range.

I've had good results with a company called "Sola". Their products
are rather expensive, but are built very ruggedly for industrial /
factory applications, rather than the cheap-plastic-cased air-
conditioned-environment PC market.

> Our current dead UPS are manufactured by a company that is dead also.

Sola has been in the UPS/power supply business for many years. They
aren't going away.

> We need both 110 and 220V UPS for our Sun4/280, 4/390 systems.

Sola makes any wattage and voltage range you could conceivably want.

> We've also had difficulty even locating any UPS manufacturers.
> (Don't they advertise?)

As a first point of contact you might try "Ace Electric and Lighting
Showcase" in Jacksonville, FL. Try information at (904) 555-1212 for
their telephone number. Tell them a Brian Bartholomew that used to
work for the CSX Systems Integration department reccomended them
(there is an outside chance someone will remember me, and Ace does a
major amount of business with CSX [the largest railroad in the
country]). This particular dealer has unusually good sales reps (i.e.
almost all of them return your calls in a timely fashion with the
specs you asked for).

There's a lot of BS surrounding standby power systems, so here's some
highly opinionated but free advice:

You don't want a ferroresonant transformer.

You don't want a motor-generator set.

You don't want a *Standby* Power Supply (SPS). With these systems
your equipment usually runs off the AC line, but when the power drops
the supply is supposed to kick in within some part of an AC cycle or
two and pick up where the line left off. This assumes:

o The computer system won't glitch when the SPS kicks in.

o The standby part still works after just sitting there for a
year collecting dust and insects.

        o The power drops off in the nice, clean, precise fashion that
          they designed the cutover circuitry for, instead of spiking
          up or waving wildly up and down while the power grid and
          all its loads tries to restablize after lightning strikes it.

Read the fine print on your literature - many vendors try to sell you
an SPS and while telling you it's a UPS.

You do want a *Uninterruptable* Power Supply (UPS). In this equipment
the inverter, the electronics that coverts low-voltage DC from the
batteries into higher-voltage AC that your equipment uses, runs all
the time. The input power from the line is used to continuously
charge the batteries. Some good features:

        o Batteries provide one of the best power filters available.
          They are physically large, and can absorb lots of power for
          short periods of time. For a typical 600 Watt UPS, the
          batteries provide, say, 800 Watts for 15 minutes (inverters
          aren't too efficient). You can see that you could dump a
          (rediculously over-massive and would take a near-direct
          strike to cause) 5-second 10,000 Watt spike into these
          batteries and it would amount to less than 10% of their
          total capacity. They would get very hot as they were
          instantly overcharged, but they might not even be damaged -
          and they would certainly protect the equipment.

        o Out of curiosity, I've watched the output of the 600 Watt
          Sola we bought for our Compaq 386 on an oscilloscope while I
          repeatedly yanked the plug in and out of the wall. The
          output voltage fell perhaps 5 or 10 volts when the plug was
          out, but the waveform never changed. Commercial power will
          vary this much over the course of a day. Needless to say
          the Compaq never noticed.

        o If you are buying insurance, why not buy something you can
          have confidence in because you know it's working correctly
          right now?

Subject: Power Protection

I. Situation Analysis

    Our company is becoming increasingly dependent upon on our data
    processing and other electronic equipment. We should consider
    purchasing an Uninterruptible Power System (UPS) to protect our
    investment. The proper UPS will protect us from power problems
    that can cost us money. It will not only back us up when power
    fails, but will provide continuous computer-grade power.

    A recent Wall Street Journal article I read detailed just how
    much businesses rely on computers. It stated " ... computers
    have crept gradually into companies, leaving top executives
    unaware of their strategic importance. They don't realize that
    the value of the information in the computer could very easily
    be worth several times the value of the hardware, software, and
    building." Over 85% of companies have reached a self-described
    state of heavy or total dependence on their computer facilities.
    A study by IBM indicated that on average a computer could expect
    to encounter over 120 aberrant power events per month. The
    damage that these problems can cause ranges from relatively
    minor transient data loss, to potentially crippling hardware
    damage. I am concerned that such damage could have serious
    adverse consequences for our operations, such as:

1) Loss of irreplaceable data

2) Decreased revenue and cash flow

3) Adverse effects on our customers

4) Failure to meet deadlines

5) Hours or even days of work (and overtime) to recover damaged
and/or lost data

6) Adverse effects on company productivity (and profitability)

        7) Management adopting an unfavorable view of the DP staff


                                                           Page 2

II. Proposed Solution

    The solution to our power problems is a well-designed UPS. This
    type of UPS will:

        1) Continue to provide computer-grade power when utility
            power fails. The UPS does this without power
            interruption. Our computer will never notice the switch
            to backup power.

        2) Continuously clean raw utility power. It will prevent
            damaging sags, spikes and surges, common to utility
            power, from reaching our equipment.

        3) Dynamically respond to load changes as well as line
            changes. High current devices elsewhere in the building
            can generate line disturbances. The UPS takes care of
            these problems.

        4) Provide spike and noise attenuation.

        5) Readily manage the switching power supplies used in our
            computers. It will also handle start-up surges well.


    There are many products claiming to provide power protection.
    Among them are standby power systems, surge suppressors and
    spike arrestors as well as UPS's. An article in a recent
    Datamation stated, "A UPS is the only type of power conditioning
    system that can provide total power protection from power line
    irregularities and even failure."

    There are two main approaches to UPS devices, double-conversion
    and ferroresonant transformer based UPS. The double-conversion
    units change AC to DC to maintain a bank of batteries. This DC
    is then reconverted to AC by the power equipment. This approach
    is inefficient since it wastes power by generating excess heat.
    It is unreliable because of a high parts count and continuous
    component stress. It cannot readily deal with nonlinear current
    requirements of switching power supplies used by all modern
    computers.

    In contrast, the ferroressonant based UPS suffers from none of
    these costly deficiencies. This makes them the clear choice for
    our needs.

Page 3

    After studying many different products from various
    manufacturers, I recommend the FERRUPS brand UPS from Best Power
    Technology, Inc. The reasons for my selection are:

        1) Best Power Technology pioneered ferroresonant
            transformer based UPS technology. Their current product
            is a third generation device with a proven field record.
            They are currently the world's leading manufacturer (in
            dollar volume) of single phase UPS.

        2) Initial cost is 20-50% less expensive than the
            competition. It has a higher efficiency and reliability
            and lower operating costs.

        3) FERRUPS is an intelligent UPS. It can communicate
            directly with a computer or terminal. All operating
            parameters are easily verified. Any alarm conditions are
            reported audibly by use of unique tone sequences.

        4) The manufacturer offers total support, before AND after
            the sale. They offer customer service plans, extended
            warranty plans, on-site maintenance and toll-free 24-hour
            telephone support.

III. Cost/Benefit Analysis

    The final cost of providing power protection will vary depending on
    exactly what equipment we decide to protect, which in turn will
    dictate the size of the UPS needed. Some sample configurations and
    costs would be:

    Size of
    FERRUPS Unit Initial Cost Equipment Protected
    ------------ ------------ -------------------
    500 VA $ 895.00 Microcomputer
    4.3 KVA $ 4,295.00 Small minicomputer & peripherals
    7 KVA $ 6,195.00 Mid-sized mini & peripherals
    12.5 KVA $10,375.00 Large local area network
    18 KVA $12,745.00 Large mini and many peripherals

    1) Based on an estimated operating lifetime of 10 years.

    2) Based on seven cents per kilowatt hour.

3) Annual cost based on three year on-site warranty plan.

    These costs are quite reasonable in the context of other
    expenditures for security, insurance and preventitive maintenance.
    For example, consider the cost of providing physical security by a
    security guard:

        Hours worked:
        -------------
        200 working days x 15 hours per day (5:00 PM to 8:00 AM)
        165 non-working days x 24 hours

        Annual Cost:
        ------------
        6888 hours x $5.00/hour ==> $30,440.00 annual cost


    Good management plans for contingencies. Human nature tends to
    believe "it will never happen to me". Since we rely heavily on
    our data processing facilities, it makes good business sense to
    protect them. Commercial power is simply not reliable enough.
    The initial and operating costs of UPS protection are far less
    than the costs of recovering from a major power outage.

    Computer-grade power, provided by the UPS is actually beneficial
    to our equipment. We will realize those benefits through
    decreased downtime and service costs as well as prolonged
    equipment life.

    I feel a UPS is an intelligent choice for our company. The
    FERRUPS from Best is clearly the most cost-efficient choice for
    us.

    Please contact me if there is anything I can help you with in
    your decision. I welcome the opportunity to oversee the
    selection, purchase and installation of this system.

           be quoted when ordering the UPS.

2. All UPS orders MUST be on a seperate order form.

3. All of the above products include the software to affect
a clean shutdown of the system.

        4. The software is supplied on 1/4" cartridge only and is
           supported on Sun3, Sun3x, SPARC and Sun4c at a minimum
           SunOS revision level of 4.0.3 (or 4.0.3c for Sun4c).

Availability:

o IBG is ready to take orders on the 5000, 10000 and 15000VA models.

o The 30000VA model will be available from March '91.

"MINDER" Description:
=====================

The monitoring software "MINDER" was commissioned by SunIBG and EPI Ltd
and is available ONLY from SunIBG. It is NOT available on it's own and
will not work with any UPS except that supplied by IBG.

The software runs as a deamon monitoring a tty port for data from the
UPS. The software can detect and give warnings on the absence of the
data cable. The software is written in such a way as to allow the
customer to customize it to his or her own needs.

The shutdown process can either be on a preset time basis ora
low-battery signal from the UPS. In either case the Low-Battery
signal will always cause the shutdown scripts to run thus ensuring
a clean shutdown.

I bought a bunch of rack mount units from American Power Conversion.
Initially, I was very impressed with the 3-Ring Binder that they
sent me that really explained a lot of things like; what a UPS is,
and isn't; How to caluclate Volt Amps; etc. When I called their
support with questions they were cheerfully answered. They are a
name brand.

Call Martha Badigian at APC. 401-789-5735.
Tell her, "Dusty Clampitt said I should call you."

implanter) from a company named Best. Another name is Sola. They

Once my grant comes through, I'll be buying several UPS's. The company that
seems to be the best (price and quality) that I have investigated is the
Best Power Company (P.O. Box 11, Necedah, WI 54646; Phone: 608-565-7200;
Toll-Free: 800-356-5794; FAX: 608-565-2221). Another company with excellent
products is SOLA Products that you can get from your local electronics
store. I buy my electronics stuff from Newark Electronics, and there are
several in the 703 area (Alexandria: 703-671-1006; Chatilly: 703-378-4604;
Roanoke: 703-345-7001; Arlington: 703-522-7552).

>> From: Andrew Kessler <kessler@schof.colorado.edu>
Lynda Mcginley forwarded your request for some info in UPSs. I'm in the
market for one for a Sun 3/60 and some Macintosh servers. It would save
me a lot of work it these machines could stand up to just 2 seconds of a
power loss. Anyway, the only one that someone I know has is made by
Best 800-356-5794. He says he's happy with it and it comes with an
RS-232 port that connects to the machine and software exists that can
shut down your machines if the outage is going to be any length of time.

Some others that might be cheaper are:

Smart-UPS - 800-541-8896

Tripp-lite. I know you can order that through some mail order house -
800-468-9044.

     I know of one company in our local area that markets a variety of UPS
     systems. It is called CIC Distributors. They not only market the UPS
     systems themselves, but software products that run on SUN, RS6000, and
     several other Unix machines, that can monitor and control the UPS, and
     trigger routines to be run on the workstation in the event that the UPS
     is utilized. We haven't gotten around to buying the product yet, but
     expect to need it one of these days. Their number is:

1-800-779-2665
