Digital High Resolution Controllers (AC digital servo)

Print

The DHC Series High Resolution Controllers provide the optimum positioner for virtually any AC powered actuator. The DHC-100 Series are directly interchangeable with the AMC or LRC Series.

  • Adaptive Control feature continuously adjusts for load and actuator conditions and positions to ±0.1° with quarter-turn actuators ranging from 2 sec to 120 sec (with or without a brake).
  • Three button control provides easy setup and eliminates the need for instrumentation, calibration procedures, and auto-cal operations.
  • Polarity Detection feature allows direct or reverse acting operation without re-wiring.
  • Electronic Brake feature (DHC-100 Series only) can eliminate need for a mechanical brake and extends brake life if used.
  • Stall Detection feature protects actuator motor from a stall condition.
  • Automatic Duty Cycle Control feature prevents shutdown of a process due to a thermal overload of the actuator motor, and allows actuators rated for 25% duty or more to be safely used.
