USED DUAL CS 5000 PSU POWER SUPPLY

IN GOOD CONDITION

it's 230 volts but - by reconnecting RP01 to the 115 V instead of the 230 V tap on the primary side of the transformer U can change it to 115V, as you can also see in the service manual on the pages 3 and 5.

and in case of the CS5000 you can forget about the 50/60 Hz issue, 'cause that model is internally DC based anyway. I.e., the incoming AC will first be transformed and then rectified (and buffered) to DC, so that it doesn't matter, whether it's 50 or 60 Hz.

I hope this helps
