[Milsurplus] pp4763a problem

[Ray Fantini]

Check your wiring! Although myself would just keep it in 120 volt operation being at full current output its only consuming around fifteen hundred watts and that will come out to around 12.5 amps at 120 volts and if you’re on a 20A circuit that’s not that big a deal. I have the old version of that power supply and run GRC-106 sets at full power on a 120 volt 20A circuit without ever blowing a circuit.
All that being said though if you have a 240 volt drop won’t hurt to use it. I have a 240/20 and two 120/20 circuts dedicated on a sub panel in the shop and that covers just about everything  including the 1 kW AM broadcast transmitter that I was running on 160 for a time.

folks. i have the big heavy 50a 24v dc power supply.  i wired it up for 230 volt. when i plugged it in it tripped the breaker.  when i checked the resistance between the 230v input with the circuit breaker on the unit open it was ..2 ohms. when i closed the breaker, same reading.  i'm just wondering if i'm picking up the coil or something else. any ideas?  thanks. jeff ciccone kg2bz
