      Replacement Onan Voltage Regulator Control Board

      Features:

      • Mounting footprint and terminal locations are identical to original board.
      • Heavy conformal coating applied for moisture and vibration resistance.
      • Improved power supply promotes cooler and more efficient operation.
      • NEW: Soft-start, field over-voltage limiting, and open-circuit external pot protection.
      • NEW: Diagnostic indicators for easier troubleshooting.
      • NEW: Adjustable under-frequency setpoint (V/F).
      • NEW: User programmable voltage sensing allows one board to cover all variants.
      • This item is built in the USA and backed by a 2-year warranty.

      Maintenance Suggestion: When replacing the Onan VR21 Controls, Flight Systems Technical Service recommends replacing the SCR Pack*. You can purchase the SCR pack directly from us or through an Onan dealer.

      *Older units may use a multi-component SCR assembly (332-0491) – if this has failed, we can convert to use the newer SCR Pack, but the assembly must be sent to our shop.
