Hi Guys,
Looking for a replacement power supply module for this active monitor. The PCB board is a self contained SMPS dual output, which I am hoping can be replaced with a suitable equivalent, but I can't really tell (even from the schematic) what the rail voltages are.
I'm thinking 300W capability, with +- 30v (approx) rails? Any suggestions please?
Thanks

I thought they ran on +-42volts.
What is wrong with it, why not repair the power supply, it is a simple circuit.

Thanks for the reply Jon. They could indeed be +- 42v. I'm just thinking with the smoothing capacitors rated at 50v, is this not a bit close to the mark? I can see my schematic has not transmitted very well, which isn't helpful!
Regarding your question, I have damaged the board on the underside quite drastically in a failed attempt to get the PWM IC lifted for replacement. I was getting about 320v at the bridge rectifier output, but nothing on the + - rails.
