I have a 24v power supply i regulate down to 12v. To run a microprocessor and some relays.<BR><BR>I then use 24v to run some hefty pneumatic solenoids. Problem is when they are under load they give ...

Solenoids at turn-on draw currentthat is much higher than the currentneeded to keep the armature pulledin. Further, because of the power dissipatedin the coil, the solenoid’s temperaturewill rise, and ...
