The 0-58719-32 is documented as a 15 A field supply board for the FlexPak 3000. Another technical listing identifies the same assembly as 707973-10T / 911FK0151 and describes it as a field-current regulator board.
Product Introduction
The Reliance Electric 0-58719-32 is a field supply board used in the FlexPak 3000 DC drive family. Its job is tied to the motor-field circuit rather than the primary armature power stage. The board is commonly identified with 707973-10T and 911FK0151, and available technical records specify a 15 A maximum motor-field current rating.
This distinction matters during troubleshooting. A failure of the field supply circuit can produce motor-field loss, incorrect field current, drive faults, or abnormal motor speed behavior even when the main drive regulator and armature circuitry appear functional. The 0-58719-32 should therefore be evaluated as part of the complete FlexPak 3000 field-control architecture, not as a generic replacement PCB.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
A common maintenance mistake is replacing a field regulator board based only on the physical connector arrangement. The 15 A field-current rating is a key configuration parameter. A lower-current FlexPak board may fit mechanically but still be unsuitable for the installed motor and drive configuration. The available FlexPak documentation also distinguishes the 0-58719-32 from lower-current field-supply variants.
Typical Applications
- Reliance Electric FlexPak 3000 DC drives
- DC motor field-current regulation
- Industrial variable-speed motor systems
- Legacy DC drive maintenance and control-panel refurbishment
Technical Pitfalls to Avoid
- Verify the 15 A rating.
The 0-58719-32 is specifically identified as a 15 A field-current board. Do not substitute a 4 A or 10 A field board simply because the physical assembly appears similar. - Check the complete board identification.
Record 0-58719-32, 707973-10T, 911FK0151, and the board revision before procurement. These identifiers appear together in available FlexPak 3000 records. - Do not confuse field current with armature current.
This board is associated with the motor-field circuit. Its 15 A rating should not be interpreted as the FlexPak 3000 drive’s overall motor or armature current rating. - Inspect the field circuit before installing another board.
Check field winding resistance, field wiring, fuses, rectifier components, contactors, and grounding. Replacing the regulator without correcting an external field-circuit fault can damage the replacement board. - Verify the drive configuration.
FlexPak 3000 systems exist in multiple power ratings and configurations. Confirm the drive model, field supply arrangement, motor nameplate data, and original board configuration before commissioning. - Check feedback and reference wiring.
The associated 707973-10T documentation describes an analog-reference and closed-loop current-feedback arrangement. Wiring errors in this circuit can cause incorrect field regulation even when the replacement board itself is functional.

Procurement and Replacement Note
For Reliance Electric 0-58719-32, verify the complete FlexPak 3000 drive model, motor field requirements, board identification, and existing field-current configuration before replacement. The critical point is the 15 A maximum motor-field current rating and the association with 707973-10T / 911FK0151.
Do not approve a replacement solely because it is labeled “FlexPak 3000 field board.” Confirm the board number and revision, field-current requirement, drive power configuration, field wiring, and feedback circuit. This is legacy hardware, so preserving the original configuration data and inspecting the surrounding field circuit before energization is especially important.
