The 500 Series Variable DC Control combines advanced engineering design, quality component selection and rigorous quality control to deliver an excellent off-the-shelf SCR based control.

Standard features, many of which are usually found only as add-on option boards, include:

  • Selectable 120/240 VAC, 50/60Hz input voltage with slide switch
  • Adjustable Horsepower settings
  • Packaged fullwave bridge rectifier
  • 1% speed regulation w/armature voltage feedback; (+,-)1/2% with tachometer feedback
  • Adjustable Minimum Speed (0-30% 0f max)
  • Adjustable Maximum Speed (60-120% of base)
  • Adjustable IR Compensation
  • Adjustable linear accelleration
  • Adjustable linear deceleration
  • Adjustable current limit
  • Line voltage compensation
  • Power interrupt relays (RC and RE versions). Permits local and/or remote switching of AC power with low current momentary contacts. Prevents automatic restart after having lost AC power.
  • 50:1 speed range
  • Overload capacity: 200% for one (1) minute
  • Transient voltage protection
  • Voltage following mode or DC tachometer follower by supplying ungrounded an analog input signal (0-12 VDC)
  • DC tach feedback (jumper selectable 3V or 7V per 1K RPM)
  • Inhibit circuit - permits start and stop without breaking AC power input voltage.
  • Shunt field supply provided (1 amp max; 100V for 120VAC, 200V for 240 VAC inputs)
  • Two (2) AC line fuses
  • Enclosed models rated NEMA 4/12
  • c.U.L. Recognised - file #E78180 (N)

See Catalog pages for the option boards that are also available for the 500 Series Control.
