          DRV- Series DC Reversingsolid-state relays offer a retrofit solution for conventional electromechanical reversers. With a solid-state H-bridge construction, the internal structure provides a natural discharge path for back-EMF generated at the motor’s turn-OFF. This results in a switch that is maintenance-free, arc-free, and noise-free.

         The Miniature solid-state reversers are our latest ultra-compact model designed to provide cost effective and reliable switching for a variety of applications.

      Selection Guidelines:

      You may submit a technical survey via, and a member of our team will get back to you with a recommendation.

      The following guidelines are generally suitable for DC motors <2HP when using DRV-Series miniature solid-state motor reversers.

      • Choose SSR with "rated voltage" at least 2xhigher the operating voltage.
      • If the DC motor does not require plugging, choose SSR with "rated current"moderately higherthan the motor's inrush current.
      • If the DC motor requires plugging, choose SSR with "rated peak current" moderately higherthan the motor's plugging current.
      • When in doubt, a good rule of thumb is to choose a SSR with "rated current" 5-8x higher than the motor's nominal operating current.
      • Size a heatsink based on highest current that will sustains over 1 second. Typically, this is the stall current.
      • Always consider adding a snubber across load terminals. This will help to suppress transients.


      Load: Thompson Actuator Part#:HD12B026-0450ELX1EESD
      [Operating Voltage]: 12 VDC
      [Rated Max Current (nameplate)]: 18A
      [Application-Specific Details]: 5A (nominal current), 15A/100ms (inrush current), 18A (rated max/stall current), plugging is not required.

      *if inrush current is not known, assume 7x the nominal current draw. Rated peak current of the SSR must be greater or equal to this value.

      Choose DRV-Series DC Reversing Contactor:
      with [rated voltage]: ≥30 VDC
      with [rated current]: ≥2x 10A
      with [rated peak current]: ≥18A
