DC Motor Reversing Solid State Relays (DRV-Series)

DRV-Series DC Motor Reversing SSRs, rated up to 1,000VDC and 200A, are used to control direction of current in DC loads such as motors, actuators, and electrochemical cells.

With a full solid-state H-bridge construction, the internal diode bridge provides a natural discharge path for back-EMF generated at inductive loads’s turn-OFF. This results in a DC switch that is arc-free, wear-free, and noise-free.

Two models are available: DRVS- Standard Model is for polarity reversing only. DRVA- Advanced Model combines the function of both a DC reverser and motor controller, thus can PWM up to 5kHz supporting various speed programs, soft-start and soft-stop programs.

Sample Applications

  • Forward and reverse control of DC motors
  • PWM speed control, soft-start, soft-stop
  • DC actuators, electromagnets, and coil reversing
  • Peltier or thermoelectric elements
  • Cathode/anode electrochemicals

          Selection Guidelines
          • Choose rated voltage ≥2x the operating voltage for inductive loads.
          • For reversing inductive loads such as DC brushed motor or DC actuators, ensure rated 200ms peak current is ≥7x the maximum current draw. 
          • SSR's rated continuous current & heatsink must be selected for the worst-case stall current ≥1second.
          • Always consider adding a RC snubber across load terminals.

          Example:

          Thompson Actuator Part#:HD12B026-0450ELX1EESD has the following specifications:
          Operating Voltage: 13 VDC
          Nominal Current (light load): 5 A
          Maximum Current Draw, Stall Current: 18 A
          Maximum Inrush Current: 54 A

          Choose DC Reversing SSR:
          Rated voltage: ≥30 VDC
          Rated continuous current: ≥18 A
          Rated peak current: ≥7x18A, or ≥130A/200ms
          Suitable SSR: DRVS01-100A
