Constant Current Power Supplies

For – Brakes and clutches, requiring up to 0.75 amperes at 24 volts, or 1.25 amps at 12 volts. (All Placid’s gold colored units)
Plug it in, connect the brake or clutch, and you’re ready to go with some simple adjustments. The Placid Ind. follower arm or ultrasonic sensor connects to the supply for constant tension unwinding / rewinding applications.

  • Easy to use – The Span adjustment scales output current for small or large brakes.
  • Precise – Current levels are maintained regardless of brake or clutch coil resistance changes due to heating.

Two User Selectable Modes

  • Manual (Potentiometer) Control – Control output current manually with a potentiometer (or with the follower arm potentiometer).
  • 0-10 Volt Control – Control output current with a 0-10 volt D.C. input signal, or Placid Ind. ultrasonic sensor.
