Re: Protek Power Supply Problems

Thanks to both.

I will start by replacing the caps.
Would the clicking sounds come from the transformer even though the problem is with the capacitors? Also, will using the low esr caps have any effect on the output even though the original ones were general purpose caps (according to the oem company)? Should I replace all of the caps with low esr ones before testing the unit?

Like I said, I'm new at this...but I'm learning.

Thanks again

I have a Protek model 60-0189-01 low voltage power supply for my CNC milling machine that is giving me problems. This PS provides both 12 and 5 volts for the machine's control system. While running the machine, the control went into alarm and the control shut down in a safe manner. After restarting the machine, the control would not power up and there was a faint clicking sound (about 4-5 Hz) coming from the Protek low voltage supply. The diagnostic LED indicator for the 5 volt line did not light and the control did not power up.

Here comes the diagnoses and repair,

Re: New Members - please post your introductions here

Hey,
A quick intro. I'm just getting into repairing my own electronics stuff. I recapped an old IBM Net Vista mother board with complete success. I'm hooked. The computer was free and the caps were less than 15 bucks including shipping. I now have a low voltage power supply that needs fixing so I'll jump on over to the threads to see if repair is feasible.

Wish me luck.
