Hi all,

I am looking for a reliable Transformerless power supply to run a PIC12F675 and a relay to drive a reticulation solenoid on my farm. The unit is powered from a 30v AC power pack and the circuit will draw something in the order of 10mA when relay is off and less than 25mA when energised.

Have looked at a few circuits but not sure which way to go... any circuits / ideas / calculations would be greatly appreciated. Oh, also the unit can't get too hot as it needs to be sealed.

Thanks

Volkov
