APC Smart-UPS 1000

Does it work on battery mode only, or completly dead?

AFAIK it can't be started unless mains was previously supplied and subsequently failed, if that is so then there is effectively no "battery only mode".

As yet I've not put a load on it (I have to make up a O/P lead) as no LEDs on the front panel light, its supposed to do a self test when the "ON" button is held for a few seconds and its supposed to beep to indicate status, it doesn't do that either.

Hold the power button in for several seconds and see if it turns on in battery mode.

Most likely it's just broken. I personally haven't heard of many people having good luck repairing APC's. There is no documentation available to troubleshoot them. NewsGuy.Com - $19.95 Unlimited Bandwidth

An instruction label on the case says hold the button for several seconds to activate self test - so obviously (and as I've already stated in an earlier post) I already tried that!

The newer units will not function without a load. A 150 watt incandescent light bulb will do.

When I looked on their website for the user manual the current offering of that unit has a choice of serial or USB, mine only has serial so I'm guessing it isn't all that new.

Just in case I plugged a domestic fan in as a load, it didn't even twitch, the outputs are a row of flush IEC plugs - I thought it possible that these might have embedded switches to disable it if nothings plugged in, but this turned out not to be the case.

There's no LEDs lit on the front panel, no feed through power, no bleeps and no sign of life from the inverter, although as I rested my hand on the chassis I'm sure I could feel it humming.

The battery fuse is an inline fuse between the 2 batteries (its a 24V inverter) this is visibly intact and I checked the 24V is getting to the transistors, the mains fuse is a button type circuit breaker and I checked

240V is reaching the board, can't see any other fuses but it isn't easy to lift the board out because of the heavy cables to the heatsinks and a very fragile flexiprint to the front panel.

If it's one of the models with a rocker switch in the back then you can start it without mains supply holding the front on button while switching it on at the back.

No rocker switch.

I just fixed mine -- shipped from APC -- it had a constant alarm buzzer when plugged in and turned on. APC internet support -- could not help.

The APC Smart-UPS 1000 uses a number of "QC" (Quick Connect) terminals. It is not uncommon for these to become loose during shipments or moves with this model.

On my unit, found one of the transformer's secondary wires from transformer not fully seated on the PC board -- that was it -- working like a champ.

When these APC units fail --- the top 3 reasons / problems:

1. Bad lead-acid batteries
2. Charger circuit bad (can not properly charge battery)
3. Internet circuit (can not produce 120 VAC from good battery).

Thanks for the suggestions, the Optimate battery conditioner pronounced both batteries good - I'll check the other points.

It is likely many UPS have been dumped for just that.

Inverter circuit?

This is the first UPS I've ever acquired that didn't have totally f****d batteries.

Sorry to be so late I just subscribed to the group. Did U get unit working, sounds to be dead power supply poss the switchmode. U could try heating it with a hairdryer to see if it starts when hot, don't cook it tho. Is poss the caps have dried out and won't allow it to start when cold, if it starts when hot caps will need replacing.
