power outage

Any research I did suggested that a square wave UPS won't work for aquarium equipment. Even an approximation to a sine wave UPS is iffy. I found a true sine wave UPS, but they were $650 each. I wanted something that would kick in while not home, but figured I should have at least something, so I went to C-Tire to get one of those Eliminator back-ups. While there, I happened upon this...

...the beauty of which is that it's automatic. This one will power a MaxiJet 1200 for 13 hours. There are bigger ones available. Up to 1500W, I think.

HTH,

HTH,

That looks like what I need. Thanks

is that not square wave also? square wave will run most of our equipment, but has problems with magnetic drive pumps and electronics. probably a few other things.

I've scoped the output from inverters, differnent UPS's and even my cheap generator and other than the ones costing thousands all basically all are a modified sinewave of some sort (some look like stacked square blocks the make the sine waveform).

Either way do know I've run my Iwaki, Reeflo and heaters on some crappy looking outputs without problems.

It's modified sine wave.

Can anyone tell if this Honda generator is a true sinewave?

hmmm, can't remember about the miodifies ones.

the modified sine wave is usually called a stepper wave as it makes a rough waveform out of squares.

HTH,

I picked up this unit on Friday at the local Canadian Tire. It was fully charged out of the box (I think someone had previously purchased it). On Saturday it ran my pump for 6 hours before signalling it was low on juice.

I then recharged it Saturday evening. The power went out as scheduled on Sunday morning and the battery pack kicked in to fire up the pump immediately. After 3 hours the readout was showing the battery to still be holding 70% of its charge. The power came on after 3 1/2 hours and the battery started its recharge program.

So I did not get a full test of it's potential. I will try that next weekend and see how long it takes to drain the battery.

What size unit did you get?...and, what is the wattage of the pump you are running on it?

Thanx much,
