i have to turn on/off half pulse of 230V, at 20mA load (a bistable solenoid valve for coolant). When i turn the load on, it is for max 20ms.
So thats a normal AC 230V, feed through a P600 diode. I need top or bottom half of amplitude, to change stance of the valve. Triacs are no use here, bcs basically i am dealing whit DC voltage, although it is pulsing. I dont want to use mechanical relays, maybe a solid state, or simply a high voltage mosfett? Any better ideas?
Thanks in advance.
