DC2 Key Attributes

  • Available in either open chassis, totally enclosed NEMA Type 12 or NEMA 4X
  • Operates from either local or remote operator controls for added mounting flexibility
  • All circuitry - sequencing, regulator and terminals - packaged on a single, accessible surface mount design printed circuit board
  • Jumper reconnections adapt standard controllers to match:
    - Line voltage, either 115 or 230 VAC, 50 or 60 Hz.
    - Desired feedback, either armature voltage or motor driven DC tachometer for non-reversing models only.
    - Tachometer requirements: 7 VDC OR 20.8 VDC or 20.8 VDC per 1000 RPM designs
    - "S" curve or linear acceleration
    - Zero speed operation
  • Separately adjustable maximum and minimum speeds set speed limits
  • Adjustable current limit protects machinery, wiring and drive
  • Adjustable IR drop compensation improves speed regulation when using armature voltage feedback
  • Adjustable acceleration and deceleration rates for smooth starts, stops and speed changes
  • 20:1 constant torque speed range
  • 30:1 constant torque speed range with tachometer feedback
  • Full-wave, half-control power conversion with back diode for efficient power conversion, smooth armature current waveforms and cool motor operation over wide operating speed ranges
  • Built-in half-wave field supply for operation of wound field motors
  • Built-in surge suppressor
  • Relay in control circuit prevents automatic restarting after power outage
  • Overload protection provided by motor thermostat
  • NEMA 4 Controls are F.D.A./U.S.D.A. approved
