Re: Database of UPS inverter output waveforms @ HWI

Got three more APC units (BK650EI, SU620INET, SMT750RMI2U).

And one more, the SUA2200I.

Nice!

I never EVER look at the output of any inverter, unless it bears a Pure Sine Wave claim and I'm running inductive loads, for the same reasons that I don't routinely examine septic tank efficiency. Cuz eww.

If you're looking for a decent UPS: my UPS is a Xantrex PROsine 2500 with 0/1 cables running through the wall to an outdoor steel cabinet full of Walmart truck batteries. It outputs a sine wave (if it's isolated during measurement) even at its safety trip point of 118VAC 29+ amps which is substantially more than its rated 2500W. It can (and has) run my PC, monitor, Asterisk server, network, and rework station, for 4 days straight. It didn't turn on its cooling fans until power was back and it had to recharge all those batteries. Those Xantrex guys sell the good stuff.

I also just got a "UNGE" sine wave inverter from the wee folk in Shenzhen. $130 means I didn't expect it to really produce 600W sine waves. I was wrong. This thing outperforms its specs by a bit less than 15% (I pushed it until it just started to clip, then backed off a little). It did that for two hours w/o overheating. It uses squirrely parts, and I'll be replacing those in a few years, but this might be a Xantrex Killer. Add two $20 Advance Auto economy car batteries and I get a 600W sine wave UPS that can run for hours for only $170.

OMG, not this crap again?! I don't want no car accumulator BS in my thread. Car accumulator belongs to car.

Re: Database of UPS inverter output waveforms @ HWI

why?

Re: Database of UPS inverter output waveforms @ HWI

Cause, well…car? ᗡ-:

Re: Database of UPS inverter output waveforms @ HWI

At least get trolling accumulators...
(hmm, was this supposed to be a double entendre post?)

[goodpsusearch]

Re: Database of UPS inverter output waveforms @ HWI

I do that since 2011 without any problems.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

Added the BR1200G.

Re: Database of UPS inverter output waveforms @ HWI

New garbage Eaton, 5E1500IUSB.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

APC SUA1000I's been finally added

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

Also the good ol' SU1400INET.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

Ancient BK400EC added. I've also started measuring inverter efficiency (at least roughly for some general idea) under full load, where possible, this has also been added for the BK650EI.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

I've added one more Eaton unit (what a garbage!) and couple APC efficiency measurements.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

More measurements of different values of units already in the DB have been added over the year, and also the ol' APC Smart-UPS 900.

[Behemot]

Re: Database of UPS inverter output waveforms @ HWI

HP T750 G2, Eurocase EA620 and Riello NDG 200 measurements have been added. Hopefully none of that will get lost with more migrations etc. as the Smart-UPS text got :-o

Re: Database of UPS inverter output waveforms @ HWI

Couple more units added lately, including pretty shameful CyberPower BU600E.
