Description
1. Product Overview
The Reliance Electric 805405-1R is a high-reliability Single-Phase Field Power Module engineered for the AutoMax SF3000 drive series. It serves as a panel-mounted unit designed to provide adjustable-voltage, current-regulated field excitation for DC motors.
Typically integrally mounted within an SD3100 DC Power Module, the 805405-1R works in conjunction with a three-phase armature power module within the same PMI rack to ensure synchronized machinery control. The module’s SCR power bridge is fully managed through the AutoMax Programming Executive software, allowing for precise integration into larger industrial automation environments.
Key Applications:
- DC Motor Excitation: Providing stable field current for high-power DC motors.
- Distributed Power Systems: Functioning as a critical component in SD3100 and SF3000 series power architectures.
- Legacy System Maintenance: Essential for supporting and repairing obsolete Reliance Electric AutoMax PLC systems.

7. FAQ
Q: Is the 805405-1R still in production?
No, production has been stopped by the original manufacturer. We supply this module as high-quality New Surplus (unused original stock) or Certified Refurbished (fully tested) to keep your legacy systems operational.
Q: Does this module require an external transformer?
Yes, the Field Power Module requires a separately-ordered, separately-mounted field isolation transformer for proper operation within the SD3100 system.
Q: What is the “Self-firing clamp” mentioned in the specs?
The self-firing clamp is a protection feature designed to guard the circuit against inductive voltage “kicks” that occur during current interruption, preventing damage to the SCR bridge.
