I have a Velleman K8004 DC to PWM module kit, that I hope to use to power a tubular solenoid with 35 ohms internal resistance. I want to pulse the solenoid with a 20v, 600mA, 50℅ duty cycle, 0 to 60 Hz variable pulse, from a 30v, 1A, DC input source. The K8004 kit has a set output frequency of 100 to 5000 Hz, and the input current is only 35mA-- while I need 0 to 60Hz, and 600mA output. The kit format gives me the ability to change specific components, and I need to know which components and their values.
