Powersupply 30-50A @ 12V with PWM input 10-100Hz or so


Is anyone aware of an off the shelf power supply (ebay is good) with PWM capable input, output about 12Vdc with high current capability say 30A to drive a solenoid at between say 100 and 100Hz?

Not off hand, but get yourself a PWM DC motor controller and modify its oscillator.
