DRV-Series Solid-State DC Motor Reversing Contactors, are rated up to 1,000VDC and 200A (continuous). They are commonly used to traverse the direction of DC motors, linear actuators, and solenoid valves.

With a full solid-state H-bridge construction, the internal diode bridge provides a natural discharge path for back-EMF generated at inductive loads’ 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 speed control, soft-start and soft-stop programs.

Sample Applications

  • forward and reverse control of DC motors & electromagnets
  • Solar tracker DC actuators
  • Cathode/anode electrochemical switching
  • Precision peltier temperature control

          Selection Guidelines:

          You may submit a technical survey via https://www.nominalcontrols.com/pages/survey1, and a member of our team will get back to you with a recommendation.

          The following guidelines are generally suitable for DC motors <3HP.

          • Choose rated voltage at least 2-3x higher the operating voltage. This is to provide adequate margin for voltage spikes and transients.
          • If DC motor will not quick reverse/plugging, ensure SSR's "rated surge current", both magnitude and duration, is significantly higher than the motor's inrush current.
          • If DC motor may quick reverse/plugging, ensure SSR's "rated surge current", both magnitude and duration, is significantly higher than the motor's plugging current.
          • When in doubt, a good rule of thumb is to choose a SSR with "rated surge current" 5-8x higher than the motor's max current as specified on its nameplate.
          • Size a heatsink based on highest current that will last longer than 1 second. Typically this is the stall current.
          • Always consider adding a snubber across load terminals. This will help to suppress voltage spikes.

           

          Example #1:
          Load: Thompson Actuator Part#:HD12B026-0450ELX1EESD
          [Operating Voltage]: 12 VDC
          [Rated Max Current (nameplate)]: 18A
          [Application Details]: 5A (nominal current), 12A/100ms (inrush current), 18A (rated max/stall current), quick reverse/plugging will not occur.

          Choose DRV-Series DC Reversing Contactor:
          with [rated voltage]: ≥30 VDC
          with [rated peak current]: ≥4x12A (100ms)
          with heatsink sized based on 18A stall condition.


          Example #2:

          Load: 1/4HP DC Motor
          [Operating Voltage]: 12 VDC
          [Rated Stall/Max Current Draw]: 20.5A
          [Application Details]: light load 8A (nominal current), 40A/50ms (inrush current), 20.5A (rated max/stall current), 100A/150ms (plugging current).

          Choose DRV-Series DC Reversing Contactor:
          with rated voltage: ≥30 VDC
          with rated peak current: 2x100A(150ms)
          with heatsink sized based on 20.5A stall conditions.

          *It is important to understand that the SSR will experience the maximum stress when it is required to switch off an inductive load during stall and/or plugging operation. For operations that require DC motor plugging, please consult us.
