POWER ELECTRONICS FOR LINEAR AND ROTARY SOLENOIDS

 

We offer some ready-to-use power electronic circuits for the control of linear solenoids and rotary solenoids:

 

Pick&Hold: these provide a maximum voltage (current) - and thus an increased force - for a defined time when switched on, which is then reduced to the holding value; this reduces the average power and thus the thermal load on the actuator; under certain circumstances, they can allow the use of smaller and also more cost-effective actuators; the peak time, the maximum voltage (or peak current) and the holding voltage (or holding current) can be set.

Pick&Drop: these are driven with a short pulse that provides the voltage for the adjustable time and then switches back to 0V.

PWM (analog): this is the analog control variant; by means of an analog voltage or current input the output voltage can be varied proportionally.

Cyclic on/off: this circuit variant enables the voltage to be switched on/off cyclically; the frequency, the duty cycle and the voltage can be influenced.

Position control: this is a simple controller circuit with PID control for a limited stroke or angle with analog feedback or encoder feedback.
