Title: Kepco JQE 25-4M modification
Post by: biotron345 on December 01, 2015, 06:45:30 pm
Recently got one of these really cheap. I'm considering adding a digital meter. I had one lying around and tested it - appears to work. Is this a sensible mod? Also I'm a bit puzzled about the patchbay of screws on the back. Can anyone shed any light on this?  :popcorn:

If you want to measure voltage and the voltimeter impedance is high enough, there is no problem to install a digital voltimeter on our PSU.

Kepco also sells these JQE power supplies with digital voltmeter + ammeter readouts.

You can download the Kepco Service manual on these links: (however there aren't for your power supply model - JQE25-4M - a "similar" should be JQE55-2)
