Physical descriptions also identify a double-width front panel, green status LED, 115 VAC input/fan terminals, multiple inductors, transformers, heat sinks, and a metal component carrier.
Application Scenarios & Pain Points
Power faults in an AutoMax rack are easy to misdiagnose because a marginal supply can create several secondary symptoms: processor resets, I/O communication loss, unexplained drive faults, or intermittent system shutdowns. Check the supply rails before replacing expensive control modules.
Typical Applications
- AutoMax PMI Systems: Installed as the system power-supply module, providing the internal DC rails required by the PMI electronics. The documented slot location is C1.
- SA3000 Distributed Power Systems: Used in high-power SA3000 configurations where the control and power architecture is distributed across dedicated modules.
- Legacy Drive Control Cabinets: Appropriate for maintaining older Reliance Electric installations where the surrounding processor, resolver/I/O, and power technology modules remain in service.
- Emergency Spare Inventory: A tested spare is particularly useful because loss of the rack supply can affect multiple downstream modules simultaneously.
Field Case:
When a PMI rack repeatedly resets, measure the 5 V and ±18 V rails under normal load rather than checking only the AC input. A supply can show the correct 115 VAC input while an aging capacitor, transformer, or switching component causes excessive ripple or voltage sag.

- Reliance Electric 0-60007-3 — Related DC power-supply board in the AutoMax PMI family. It belongs to the same supply architecture but has a different assembly designation; do not assume direct interchangeability.
- Reliance Electric 0-60007-1 — Another DC power-supply card in the AutoMax PMI product family. It is a related supply assembly, but the complete system configuration must be checked before substitution.
- Reliance Electric 0-60021-4 — PMI Processor Module. It works alongside the power supply but performs the processor/control function rather than power conversion.
- Reliance Electric 0-60031-5 — Resolver and Drive I/O Module. This provides resolver and drive-interface functions and depends on the PMI power architecture for operating power.
- Reliance Electric 0-60002-5 — DC Power Technology Module. It belongs to the SA3000/PMI power architecture but performs a different function from the 0-60007-2 supply.
- Reliance Electric 0-60002-6 — Related DC Power Technology Module with a different configuration. Useful when servicing the same broader SA3000 power system, but not a substitute for the power supply.
- Reliance Electric 0-60028-2 — Gate Drive Interface Module. It operates farther downstream in the drive power-control chain and should not be confused with the system power supply.
- Reliance Electric 0-60031-2 — Resolver and Driver I/O Module. It provides a different interface function within the SA3000/AutoMax architecture.
The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do Not Confuse 0-60007-2 With 0-60007-3
The part numbers are extremely close, but they represent different supply assemblies. The PMI inventory lists them separately.
How to avoid it: Match the complete part number, board revision, connector arrangement, and system documentation before installing the replacement.
⚠️ Verify the 115 VAC Input and Output Rails
The documented 0-60007-2 uses 115 VAC input and supplies 5 VDC and ±18 VDC internally.
How to avoid it: Measure all supply rails under load. Do not conclude that the module is healthy simply because the front PWR OK LED illuminates.
⚠️ Do Not Ignore the Airflow Switch
The module includes an airflow-monitoring function, with documentation identifying a 50 FPM airflow switch.
How to avoid it: Check the fan, airflow path, switch wiring, and cabinet ventilation. A replacement supply can experience the same problem if inadequate cooling caused the original failure.
Frequently Asked Questions (FAQ)
What is Reliance Electric 0-60007-2?
It is a DC power-supply module for Reliance Electric AutoMax PMI and related distributed-power systems. It accepts 115 VAC and supplies the internal DC rails required by the control architecture.
What voltage does 0-60007-2 require?
The documented input is 115 VAC. The module also provides 115 VAC fan power through its associated terminals.
What DC voltages does 0-60007-2 provide?
Available technical information identifies 5 VDC and ±18 VDC power supplies within the module. These rails support the electronics of the associated PMI system.
Is 0-60007-2 used in systems?
Yes. The module is documented for high-power modules with distributed power systems, as well as AutoMax PMI applications.
Can I replace 0-60007-2 with 0-60007-3?
Do not assume so. Both are listed as AutoMax PMI power-supply products, but they have different part numbers and may correspond to different hardware configurations.
For a replacement, compare the complete module number, revision, connectors, system slot, and original system documentation.
What should I request when buying a refurbished 0-60007-2?
Ask for:
- Actual module photographs
- Complete 0-60007-2 marking
- PCB revision/date code
- Front-panel and terminal photographs
- 115 VAC input test
- 5 VDC and ±18 VDC output measurements
- Load-test results
- PWR OK verification
- Fan/airflow-switch verification
- Inspection for capacitor leakage and heat damage
- Warranty terms
For this module, a simple “powers on” statement is weak evidence. The important acceptance test is whether the required DC rails remain within specification under an appropriate load.
What is the biggest replacement risk?
Using the wrong PMI power-supply revision or overlooking the cooling circuit. The 0-60007-2 is responsible for system-level power, so a marginal supply can create symptoms that resemble processor or I/O failures. Its airflow monitoring also means fan and ventilation problems should be investigated as part of the repair.
