Application Scenarios & Pain Points
Power-supply failures are sometimes misdiagnosed because the controller itself may continue operating while field I/O, relays, communication equipment, or transmitters begin dropping out. With a 500 W supply, the load profile deserves attention before installing a replacement.
- Industrial control cabinets: Provides a high-current DC bus for PLC, DCS, I/O, instrumentation, relays, and auxiliary control equipment.
- Automation equipment: The 24.7 VDC output is appropriate for systems designed around a nominal 24 VDC control rail.
- Marine and industrial equipment: The part-number cross-reference associates the unit with ABB marine/turbomachinery equipment as well as the LXN1604-6 designation.
- Legacy system maintenance: Useful where the original cabinet was designed around this specific LXN power-supply assembly and a modern replacement would require rewiring or mechanical changes.
Field note: Measure the 24 VDC rail with the cabinet under realistic load. A supply that reads 24.7 VDC with almost no load tells you very little about its behavior when contactors, I/O cards, and transmitters are drawing current simultaneously.
Brief Field Case
A cabinet with intermittent PLC resets may initially look like a CPU problem. If the DC rail dips when several outputs energize, the real fault can be the power supply or an overloaded downstream circuit. Checking voltage at both the supply terminals and the far end of the DC distribution makes the distinction much easier.

The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — Do not size the replacement from voltage alone.
Both the original and replacement may be labeled “24 VDC,” yet the available current can be very different.
How to avoid it: Verify the actual cabinet load. The is specified around 20 A / 500 W, so a lower-rated 24 VDC supply should not be treated as equivalent simply because its nominal voltage matches.
WARNING 2 — Check the input range and installation environment.
The documented input range is 85–264 VAC, with an operating temperature specification extending from -40°C to +60°C.
How to avoid it: Confirm the incoming AC supply, cabinet temperature, ventilation, and derating requirements. A power supply mounted above a hot drive or braking resistor may experience conditions quite different from the nominal cabinet temperature.
WARNING 3 — Do not overlook mechanical fit and wiring.
The is listed at approximately 194 × 113.6 × 138 mm and is associated with DIN-rail installation.
How to avoid it: Before ordering an alternative, verify:
- DIN-rail position
- Terminal arrangement
- AC input wiring
- DC output polarity
- Protective earth
- Clearance
- Cabinet ventilation
- Output distribution wiring
Also inspect the terminal screws and nearby wiring for heat discoloration. That small detail can reveal years of overload or poor termination.
Frequently Asked Questions (FAQ)
What is ABB ?
is a 500 W industrial AC-DC power supply associated with ABB part number 3BHL000986P7000. Available technical records specify approximately 24.7 VDC at 20 A output.
It is best treated as a cabinet-level DC power source rather than an automation CPU or I/O module.
What is the output voltage of ?
The listed output is approximately 24.7 VDC, with a maximum output current of 20 A, giving a nominal power rating of approximately 500 W.
That output is intended for equipment designed around a nominal 24 VDC industrial control supply.
What is the input voltage range?
The available component data specifies 85–264 VAC input.
This wide range allows the supply to operate across common single-phase industrial AC systems, but the actual plant supply should still be measured before commissioning.
Is 3BHL000986P7000 the same as ?
Yes. The part-number cross-reference directly associates 3BHL000986P7000 with .
For purchasing, I recommend specifying both identifiers:
ABB — P/N 3BHL000986P7000
This reduces ambiguity in legacy inventory systems.
Is a DIN-rail power supply?
Available technical specifications identify the unit as a DIN-rail power supply, with approximate dimensions of 194 × 113.6 × 138 mm.
Before fitting a refurbished unit, inspect the mounting hardware and terminal arrangement. A mechanically compatible supply still needs sufficient ventilation and conductor clearance.
Can I replace with another 24 VDC power supply?
Not automatically. At minimum, compare:
- Input voltage range.
- Output voltage.
- Continuous output current.
- Peak/inrush capability.
- Load distribution.
- Protection behavior.
- Physical dimensions.
- DIN-rail mounting.
- Terminal arrangement.
- Ambient-temperature derating.
For a 500 W cabinet supply, the transient response and overload behavior can matter just as much as the nameplate voltage.
What should I request when buying a refurbished ?
For a production spare, request:
- Exact marking.
- 3BHL000986P7000 part-number photograph.
- Input-voltage test.
- 24 VDC output measurement.
- Load test approaching the rated operating range.
- Overload/protection test where practical.
- Insulation/withstand test appropriate to the refurbishment process.
- Terminal inspection.
- DIN-rail mounting inspection.
- Actual unit photographs.
- Written test report.
- Warranty.
A no-load voltage measurement is only the first check. For a 500 W supply, a meaningful load test is much stronger evidence of condition than simply confirming that the output reads 24 VDC.
