Annoucement:

DRVS01-60A3-SP has been discontinued, replaced by DRVS01-60A3-SPV with improved 3kV Input/Output Isolation Voltage.

New 2026 models addressed an issue with operating at elevated ambient temperature conditions observed on earlier models.

Description:

          DRVS- Series miniature DC Reversing solid-state relays retrofit 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.

         Our mini solid-state reverser models 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 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 <2HP when using DRV-Series miniature solid-state motor reversers.

• Choose SSR with "rated voltage" 3x higher the operating voltage.
  
• Choose SSR with "rated current" marginally higher than the motor's heavy-load current
• Choose SSR with "peak current" marginally higher than the greater of motor/actuator's inrush and stall current
  
• If the DC motor requires plugging, choose SSR with "rated peak current" moderately higher than 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. 
  
• Always consider adding a snubber across SSR's L1 and L2 load output terminals. This will help to suppress peak transients.
  

Example:
Load: DC Actuator
[Operating Voltage]: 12 VDC
[Rated Max Actuator Current (as shown on name plate)]: 36A
[Application-Specific Details]:

• 10A (nominal current, light load)
• 30A (peak current, heavy load)
• 60A/100ms (inrush current) *if inrush current is not known, assume it's 8x the nominal current draw.
• 65A (max stall current). *DURATION MUST BE EXTERNALLY LIMITED to prevent damages to the SSR, other electronics and the motor/actuator
  
  

Choose: DRV-Series DC motor reversing solid-state relay:

• with [rated voltage]: ≥36 VDC; 3x rated voltage
• with [rated current]: ≥45 A; marginally higher than heavy load current
• with [rated 1 second peak current]: ≥100 A; marginally higher than inrush current
• fuse SSR with: 40A or less, depending on expected duration of heavy-loading. It's 1 second melt current must be marginally lower than SSR's rated peak current
