OT / Hardware issue ->APC RS1000 UPS output= 162volt (220v unit) when on battery

Fernando Cassia-2
Hi there,

This is slightly OT, but also slightly On-topic for this list as this
is probably the list with more APC-savvyness per square inch ;):

I wonder if anyone on this list has experience with faulty APC RS1000
units which when switching to battery power, output LOW VOLTAGE (in
the case of my APC RS1000, 162 to 163 volts instead of 220v).

To be clear: everything seems to "work right". No beeps, no alarms,
battery lasts as it should, but when you measure the AC output, it's
220v when plugged on AC and when you unplug it from the socket and it
switches to battery, the output voltage becomes 162v.

I have three of such units, which I got at an auction for a very low
price. I'm weary of plugging anything that uses AC directly) like a
PC, and so far I've used it with Ethernet routers and other such
inexpensive kit that have AC->DC 5v2A or AC->12v2A or AC->19v3A
external power bricks (which, in case of failure, I can easily source
and replace inexpensively)...

The batteries are OK, and hooked ok, (24v total, 12v9AH connected in
series, w the plastic and interconnect wire).

I did some visual inspection on all three and I saw no bulged
capacitors nor burned components, all is very clearn. All three units
appear to have been repaired, as I saw the classic "market dot on
capacitors" left when someone probes components in the process of
repairing them.

Would it be possible that someone replaced components on the inverter
section and by mistake used components for the 110v output version
instead of 220v?. Is there any other list where electrinics wizards
hang out that could give me a hand in attempting to troubleshoot this?

Or is this a known issue with the RS1000 line?.

Thanks in advance.

Hello,

Your UPS is most likely all fine.
If you are measuring the output voltage with a cheap multimeter, you will read only 150-170 volts AC output. This is because your multimeter is not true-RMS, and cannot read AC voltages correctly if the AC waveform is not sinusoidal. APC Back UPS RS 1000 has square waveshape on battery, so that's why you see incorrect value on your multimeter. The effective voltage present there is probably 220-240 volts, just your multimeter displays lower value.

Hope that helps.

But that doesn't explain why the APC Back UPS CS 350 and RB 500 mesure
the right voltage, using the same multimeter. (?). And why it blew the
Watts Up Pro.

I must check the release date on the RS 1000... the only possible
explanation is that it's a much older technology than the other two
mentioned APC models.. (which are smaller and cheaper)

Had it not blown the Watts Up Pro, I'd probably have hooked something
to them and not measured the output at all...

Mihalik Máté

I've had Back UPS CS 350 as well. My multimeter showed 200-214V output when it was on battery, but it just means it manages to make the multimeter "think" it is closer to sinewave (in reality I think it has a triangular looking waveform, but you'd need an oscilloscope to see it for yourself.)
Your device probably blew up because it didn't like the square wave output of the Back UPS RS 1000. It wouldn't have blown up just because receiving lower supply voltage. (I bet it just wouldn't turn on with a low voltage like that).

First Q - how did you measured voltage (what kind of equipment) - many simple multimeters got false reading when waveform is not quiet sine.

Here is someone who did put an actual scope on them:

http://www.jkovach.net/projects/powerquality/

It isn't that the waveform from the BackUPS "isn't quite sine"    It is
that the waveform from the BackUP is nothing at all like a sine wave.
In fact it's decidedly NOT a sinewave.

So don't blame the multimeters.  A top of the line voltmeter isn't going
to make head or tail out of what the BackUPS puts out anymore than the
free Harbor Freight specials do.

Well, only 'true RMS' gauges can get it correctly, however RMS readings on square vaves would be also inaccurate. The best way is get an osciloscope and see what really goes out ;)

I will try to borrow an oscilloscope and have some fun.

Your welcome - I was pretty shocked myself when I looked them up.
I knew the BackUPS series was not sine wave but I figured they
would at least -try- to make some sort of approximation to a sine
wave.

Reminds me of Scotty's classic line from Star Trek TOS:

"It's...It's...It's Green"

With the BackUPS change that to:

It's...It's...It's Power"

As a side note, best to keep your old APC units instead of buying new ones. I've seen and used many older APC units (those from the 1990 leading up to 2004, 3 different generations), these units have tipically through-hole circuit boards (not SMD) and very high build quality. Replacing the capacitors after every 7-8 years or so keeps them running very reliably. Many rich countries dumped these in favor of the new ones, that's why I find myself luckly to live in a relatively poor country compared to western europe, where old units are still kept because of the high prices of the newer ones.
The reason is simple, older units were manufactured with a different point of view in mind. Nowadays build quality is biased towards being the cheapest (yet selling at high prices) due to consumer society (aka buy it and throw it out), whereas in the 1990's reliability and usability was more important than endless greed.
My PC is guarded now by an APC Smart-UPS 900 (2nd. gen) which was made in 1994 and still running well, and I haven't even replaced its factory default (22 year old) capacitors yet!

Though I still have one SmartUPS1400XL running, I've understood that the older "beige" units had the propensity to over-charge their AGM batteries.  Yes, I know there is a way to tune this for better life but I heard that the newer units were better on batteries, more efficient, etc.  The shorter life of the UPS isn't all that surprising to me though disappointing.
