2. Product Introduction
Regulating and supplying precise excitation current to DC motor fields under heavy industrial loads requires high-accuracy power conversion and advanced monitoring circuitry. Operating as a critical subassembly within Reliance Electric’s FlexPak 3000 digital DC drive platform, the 0-58719-32 Field Supply Board Assembly manages motor field current up to 15A max.
Engineered with built-in field loss detection, field economy functions, active overvoltage protection, and precise thyristor/SCR firing control, this regulator ensures stable torque output and secure motor operation. Plant maintenance engineers, electrical technicians, and system integrators rely on this exact OEM regulator board to maintain high performance and prevent thermal or electrical damage across legacy DC motor control loops.

4. Global Compliance & Industry Certifications
DC drive components and field regulator electronics deployed in heavy industrial manufacturing lines must adhere to strict electrical safety and quality standards.
- Certifications: CE Conformity, UL Listed Industrial Control Equipment standards, and ISO 9001 factory manufacturing quality compliance.
- Safety Relevance: The integrated field loss protection and overvoltage safeguards instantly trip or ramp down the drive upon detecting open-field conditions, preventing dangerous motor overspeed and mechanical destruction.
- Audit Note: Keep board calibration logs, parameter configuration records (via drive software or keypad), and preventive maintenance inspection histories accessible in your computerized maintenance management system (CMMS) to satisfy electrical safety audits.
5. Long-Storage & Asset Preservation Guide
Spare DC drive regulator boards stored in warehouse stockrooms face electronic component aging, electrolytic capacitor wear, and electrostatic discharge (ESD) vulnerabilities over extended storage cycles (—requiring strict environmental control to ensure immediate deployment readiness). Preserve your asset by executing these procedures:
- Maintain indoor warehouse climates where storage temperatures stay between +10^\circC and +30^\circC while keeping relative humidity strictly below 60% non-condensing.
- Keep the board permanently sealed inside its original factory anti-static moisture-barrier bag alongside active desiccant packs until the exact panel maintenance window.
- Protect gold-plated edge connectors and sensitive semiconductor components from dust accumulation, mechanical impacts, and chemical tarnish.
6. Physical Installation Prerequisites
Proper slot alignment, static discharge precautions, and total drive power isolation are mandatory when installing or replacing field supply boards.
- Clearance Space: Ensure unobstructed airflow pathways inside the FlexPak 3000 enclosure to allow proper thermal convection across power-handling components.
- Grounding Requirements: Always wear an approved ESD wrist strap tied directly to the drive chassis ground stud before handling or sliding the board into position.
- Power Isolation: De-energize and lock out (LOTO) incoming AC line power and discharge internal DC bus capacitors completely before installing or extracting the 0-58719-32 board to prevent severe electrical shock hazards.
7. Buyer’s FAQ (Logistics & Compliance Focus)
Q: What Harmonized System (HS) Tariff Code applies to this Reliance Electric field supply board for international shipments?
A: Industrial DC motor drive parts, electronic controller subassemblies, and electrical automatic regulators typically classify under HS code 8504.40.9580 or 8538.90.8180. Always verify final classifications with your customs broker.
Q: Can the 0-58719-32 board be used as a direct replacement in lower-current FlexPak 3000 drives?
A: It is rated up to 15A max. While higher-rated boards can technically drop into lower-current frames, ensure your drive configuration parameters match the specific motor nameplate requirements to maintain optimal control resolution.
Q: What is the Country of Origin (COO) for trade compliance record-keeping?
A: Reliance Electric / Baldor drive components are manufactured in certified production facilities (primarily the United States), requiring accurate origin declarations on commercial import paperwork.
Q: Is specialized shock-resistant transit insurance required for international cargo delivery?
A: Yes, because precision multi-layer printed circuit boards and sensitive semiconductor components are vulnerable to heavy drop impacts and shipping vibration, full-value freight insurance is strongly recommended.
