APC Power Back Up

[sugi]

Just visited Commex and saw APC power back up.

ES series 500VA 300W.

Able to support 20 min of desktop PC and 17" monitor.

Has anyone us this before ?

Usual price is $89 but Commex price $69.

Decided to buy one and try to back up my Tunze

and see how long can it sustain.

WOAH that's a big lobang!!!!

[weileong]

this one is stepped sine wave can only be used for running PC

You'll need the smart-UPS.

Weileong, Whats the difference between the smart UPS and this series? I think still can run the Tunze streams rite?

[weileong]

The smart UPS series produces true sine wave. The non-smart UPS produces a stepped sine wave.

I've not tried running my tunze with the ES series but Roidan has tried and he can relate more abt the results

[roidan]

the output from the stream decreased using stepped sine wave UPS...

from my personal observation.

IC, thanks... tot it can work with tne Tunzes and wanted to get one tomorrow Cos my Smart-UPS needs to have its battery changed (Cannot retain the charge for long)

[weileong]

Just get the batteries change, they aren't that $$$. I got mine changed few weeks back, there's a shop at the basement of SLT that sells the gel cell. Just tell them the rating and they will give you the correct one. It's all standard sized.

No need to waste money get original APC one

[AlfaRomeo]

How much did you get your replacement batteries? APC quoted about $100 for the replacement...

[weileong]

Which model are you using alfa?

I paid close to $100 for mine. APC quoted $180.

[AlfaRomeo]

Im using the SMART-UPS 700

[weileong]

ah.... mine is SMART-UPS 1000. Probably the battery cost ard $60 if I remember correctly.

[firestream]

I always wonder is that possible to connect those APC to normal car battery ... which is cheaper & offer larger capacity .... hee hee.

[weileong]

You can of course but it is back to charging cycle you might blow the charging circuitry due to the high surge current.

Car batteries are useless for deep cycling purpose. Get a deep cycle battery
