Input Voltage too HIGH
Input Voltage too HIGH
(OP)
Hi,
I have a number of computers attached to a UPS, which is only at 30% load. The problem seems to be the input voltage, it keeps saying that it is too high.
It fluctuates during the day and stays at around 240-245 then at night it goes up and down between 240-255.
Everytime I get an email from my UPS saying it has had a frequent overvoltage so it trims it down(Its highest setting is 253V)... surely this will cause me problems eventually.
Anyone have a solution on what to do to stabilised it?
Kind Regards
Mark

RE: Input Voltage too HIGH
It may even save you some money on your power costs. Incandescent lighting and resistance will use less power.
If this approach is not feasible, you can use a bucking transformer to drop the voltage a little. You need a transformer with a 240 volt primary, and a 6 volt secondary. The transformer should be rated for buck-boost service.
The third approach is to add a voltage regulator ahead of the UPS.
