The 1000 watt rating of the transformer is only telling you the MAX wattage you can pull through that transformer before you start to overheat the windings and risk destroying it.
I would be a whole lot more concerned about the 50Hz vs. 60HZ issue. |
It will probably use 90 to 130w due to electrical inefficiency (transforming 220 50Hz to 24-28VDC to charge the battery, and then transforming it back to the desired line voltage)
I'm sure that APC/other UPS makers have a model to fit that need, if all the devices are externally powered (wall wart/power brick) you might be able to get the correct model for the local current and use a standard local UPS (might be cheaper than a specialty model UPS) |
