Use these constant current-type power supplies with magnetic particle brakes & clutches, and hysteresis brakes. These precise units maintain current levels regardless of brake or clutch coil resistance changes due to heating. Available in both 110 & 220 VAC (50/60 Hz) configurations.

PS Power Supplies

For use with our small brakes and clutches, and available in both enclosed (bench-top) and open configurations.  Control output current with the potentiometer knob or a 0-10v signal.  Scalable output current range allows precise control, even for miniature brakes & clutches.  Connects to the Placid Industries follower arm potentiometers or ultrasonic sensor for constant tension unwinding / rewinding  applications.

PST Power Supplies

For use with all our large brakes and clutches.  Output is 24 Volts DC, with 2, 3, and 4 Amp versions. Control output current with the potentiometer knob, 0-10 volt or 4-20mA signal.

PSH Power Supplies

For use with all our large brakes and clutches or multiple smaller ones.   Output from 0 - 30 Volts DC with 2, 3, and 5 Amp versions.  Control output current or output voltage with the potentiometer knobs.
