I am working on a prototype project with a large electromagnetic solenoid. I want to be able to vary the strength of the solenoid via a PWM (preferred), or constant current.
The issue I’m having is that I want to turn the solenoid on and off rapidly (1-150 Hz). I am currently using a bench power supply at about 1500 W and a large solid-state relay that is triggered by a proximity switch. The bench power supply is operating the solenoid, but it’s hard on the power supply to be turned on and off rapidly. I have tried a PWM controller, but it had a soft start feature which retarded the power to the solenoid.
I need an amplifier or motor controller that can handle rapid and continuous "instant on" and "instant off". The solenoid can handle a maximum of 96 V and 500 A for short periods of time and ultimately I want to run the system from batteries.
