Hi All,
Im hoping to use a simple 555 circuit with mosfet (low side) output to drive a solenoid, Im confused over the specs of the solenoid i will need. Am I right to think that I can replace a 24V 12W solenoid with a 6V 3W on a 25% duty cycle at 24V?
The main trouble with the 24V 12W is the heat it generates when continuously on, would the pwm solution run hotter/cooler? Also what is a ideal frequency for the solenoid pwm signal, I'm trying for 20kHz and up to avoid being able to hear it is this the right idea?
Thanks,
Nodee
