Technical Introduction

Failure of 0-58719-32 removes regulated excitation power to the DC motor field winding. Loss of field current triggers drive field loss protection trip, motor speed runaway risk and immediate process shutdown. Winders, extruders, rolling stands and other DC motor loads stop, creating production scrap, mechanical equipment damage and unplanned downtime.

Reliance Electric 0-58719-32 is a 15 Amp field supply PCB assembly built for FlexPak 3000 series digital DC drives. It provides controlled excitation current for shunt DC motor field coils and implements field weakening control to extend motor operating speed above base speed. The board assembly includes power resistors, small transformers, rectifier diodes, relay and terminal connectors, mounted on a metal backplate for mechanical support and heat dissipation. It receives command signals from the main drive regulator card, monitors field current, and feeds back status signals for drive fault diagnostics and protection interlocks. Widely used in web handling, metal rolling, extrusion and heavy-duty industrial machinery equipped with Reliance FlexPak3000 DC drives. Industrial reliability teams stock 0-58719-32 to restore DC motor field excitation and full speed range operation.

• Best Suited For
  • Reliance FlexPak 3000 digital DC drive cabinets
  • Shunt DC motor field excitation, field weakening and field current regulation
  • Direct drop-in replacement for existing Reliance 0-58719-32 field supply hardware

Core Technical Specifications

Field Engineer’s Tech Notes

• Confirm full part revision, motor field nameplate rating, FlexPak3000 firmware and field current setpoints before replacement; mismatched field current parameters can trigger field loss trips or motor field winding burnout.
• Perform lockout/tagout of main AC incoming power and motor armature/field circuits before board removal. High residual voltage remains in field winding and power capacitors after shutdown.
• Inspect power connectors, resistors for thermal discoloration, cabinet cooling fans and heat sink dust accumulation; overheating and loose terminals are the most common root causes of field board failure.
• After installation, verify cabinet power-up, field current calibration, field weakening ramp response, field loss fault simulation and armature/field interlock protection. Test full speed range operation, validate drive fault reporting, clear faults and remove lockout before returning production load online.
• ESD protection required while handling PCB assembly.
• Inspect field wiring insulation and terminations as part of drive preventative maintenance.

Adaptive QA & Testing Protocol

Each 0-58719-32 field supply board assembly is bench tested on FlexPak3000 test drive setup. We verify power excitation output, 15A load test, field current feedback accuracy, field weakening response and fault interlock signal. PCB, power resistors, relay, connectors and solder joints are visually inspected for thermal discoloration, burn marks or corrosion. Full test reports are available upon request.

Buyer’s FAQ

Q: What is Reliance 0-58719-32 used for? A: It is a 15A field supply board for Reliance FlexPak3000 DC drives, supplying regulated excitation current to shunt DC motor field coils and enabling field weakening for higher motor speed operation.

Q: What warranty applies for refurbished and NSFP 0-58719-32? A: Refurbished and NSFP units carry a 12-month hardware warranty. Coverage excludes ESD damage, overheating from poor cabinet cooling, field wiring faults, motor winding damage and incorrect drive parameter setup.

Q: What lead time should I expect? A: Stocked units ship 3–7 business days. If inventory depleted, we source surplus Reliance 0-58719-32 field supply assemblies.

Q: Can 0-58719-32 be hot swapped? A: No. Drive AC power and field circuit must be fully locked out and discharged before board removal; hot swap is not supported.

Q: Is 0-58719-32 still in production? A: No, FlexPak3000 series including 0-58719-32 is end-of-life legacy DC drive hardware.
