Power Driver Module
SDM950

High Performance Pick and Hold Solenoid Driver Module SDM950 is designed to avoid over heating of the solenoid coil once it is energized.

This is done by applying an initial higher voltage to the solenoid coil to provide the necessary force (torque) to pull the plunger in. Then, when seated, drops the voltage down to a level sufficient to maintain the plunger in the seated position.

To apply the control voltage, a DC power supply could be used.

The pick time and hold voltage are variable and set using the onboard potentiometers.
