4. Product Introduction (Anti-Template)
The Reliance Electric 805405-1R is a panel-mounted single-phase field power module from the SF3000 / AutoMax family. It supplies adjustable-voltage, current-regulated field excitation for DC motors at a rated output of 15 A. The module accepts a wide AC input range of 120 to 460 VAC and uses a non-reversing (S2) SCR bridge.
It is designed to operate in conjunction with a three-phase armature power module sharing the same PMI rack. The SCR power bridge is controlled through the AutoMax Programming Executive software. Built-in protection includes an electrically isolated power cube with dv/dt protection, internal AC line fuses, and a self-firing clamp for inductive voltage kick. Production of this module has been discontinued by the original manufacturer; exact revision and system compatibility must be verified when sourcing a replacement.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full part number (805405-1R), revision labels, and physical condition of power terminals and connectors. Photograph all labels.
- Functional Testing – Limited standalone testing is possible. Full validation requires installation in a compatible SF3000 / AutoMax system with the associated armature module and control software.
- QA & Packaging – Protect power terminals and electronics, clean according to industrial electronics handling practices, and pack securely for heavy industrial modules.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial power conversion / drive modules. Packaging must protect terminals and the power cube; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
System Compatibility – Confirm the module matches the existing SF3000 / AutoMax / SD3000 configuration and PMI rack.
Field Current Rating – Do not exceed the 15 A continuous rating. Verify motor field requirements.
Software Control – The module is managed through AutoMax Programming Executive; configuration and tuning must match the original application.
Protection Devices – Internal fuses and the self-firing clamp are critical. Do not bypass protective features.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified 805405-1R?
As a discontinued Reliance field power module, availability depends on surplus and refurbished stock. Typical lead time after verification is 1–4 weeks plus standard shipping.
What is the primary function of this module?
It provides single-phase, non-reversing field excitation (15 A) for DC motors in AutoMax / SF3000 drive systems.
What is the output current rating?
15 A.
What AC input voltage does it accept?
120 to 460 VAC.
Is this module still in production?
No. Production has been discontinued by the original manufacturer.
What should be confirmed before ordering a replacement?
Exact part number (805405-1R), compatibility with the existing AutoMax / SF3000 system and armature power module, and field current requirements of the motor.
