Is my APC Line R LE1200 acting funny?

This was originally posted on APC forums on 11/24/2007


I set the switch at the back for 120V (Canada)

I plugged it in and it clicked to the yellow light indicating overvoltage and stayed there

I checked the voltage at the wall with my meter and it was 123.8V

I checked the voltage at the LE1200 at it was 110V

Is that right? seems like a pretty big drop in voltage to me.

I didn't think it would register overvoltage on the unit unless the wall voltage output exceeded something like 127V

Can someone help me? the instructions included with the unit don't seem to be of much use in this situation.

cheers

If the unit does go begin trimming the voltage, it will trim 12%. That explains the 110v you're seeing on the output of the unit. Have you tried setting the voltage tap to 127? Try measuring the output at that point.

yes. when I change the setting to 127V the machine stays green and gives me the same voltage as whatever the wall is doing.
So I'm trying to decide if its safe to run the equipment at 110V. They are synthesizers which are essentially computers however they run off transformers which themselves I guess take the input voltage and convert it to DC. I know for a fact that at least one synth will accept anything over 100V so theoretically shouldn't be a problem.
