Description
Product Introduction
The ABB LXN1604-6 3BHL000986P7000 is a 27 VDC, 500 W industrial power supply unit intended to provide regulated DC power for industrial electrical and automation equipment. The ABB product identification is unusually clear on this part: product ID 3BHL000986P7000, type designation LXN 1604-6, and catalog description LXN 1604-6, 27V 500W; POWER SUPPLY.
The ABB LXN1604-6 is therefore best treated as a power-conversion component rather than a PLC, communication module, or Ethernet switch. A 27 VDC / 500 W rating corresponds to approximately 18.5 A at rated output. Its relatively large 194 × 113.6 × 138 mm package and approximately 2.96 kg net weight indicate a substantially higher-power industrial supply than the small DIN-rail supplies commonly used for individual I/O stations.
There is considerable conflicting secondary-market information surrounding this part number. Some listings incorrectly describe LXN1604-6 as an Ethernet switch or a generic redundant power module, while another technical cross-reference identifies the part as an AC-to-DC converter with a 27 V, 500 W output. The ABB identification and distributor documentation consistently support the power-supply classification.

The 27 V / 500 W rating and mechanical dimensions are directly supported by the available ABB product identification data.
Input-voltage caution: Some reseller pages claim very wide AC and DC input ranges, including 85–264 VAC and 90–350 VDC, but I would not treat those figures as confirmed for the exact LXN1604-6 without the original ABB/Power-One datasheet or the unit’s nameplate. The available authoritative product identification establishes the 27 V / 500 W output, but the search evidence is insufficient to safely assert a universal input range.
Application Scenarios & Engineering Considerations
The LXN1604-6 is applicable where a high-capacity regulated DC bus is required for industrial electrical equipment.
- Industrial automation cabinets: Provides DC power to control and interface equipment where the 27 V output is appropriate.
- Power-conversion systems: Converts an available AC/DC input source into a controlled 27 VDC supply.
- Legacy ABB installations: Particularly relevant when maintaining equipment originally specified with the ABB material number 3BHL000986P7000.
- Marine and industrial equipment: The same part number appears in historical equipment and military/industrial cross-reference records as a 27 V, 500 W AC-to-DC converter.
Engineering point: Do not substitute a conventional 24 VDC / 480 W supply simply because the nominal voltage appears close. The specified output is 27 VDC, and the downstream equipment may depend on that exact voltage range.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not confuse LXN1604-6 with a communication module.
Some secondary listings incorrectly categorize it as an Ethernet switch. The stronger product identification clearly describes 3BHL000986P7000 as a 27 V, 500 W power supply.
⚠️ Verify the input voltage before energizing a replacement.
The output specification is well established, but available online sources disagree significantly about the input range. Do not rely on a reseller’s generic specification.
How to avoid it: Read the original nameplate and wiring diagram and verify the exact input configuration before connecting power.
⚠️ Do not substitute based only on wattage.
A 500 W replacement with a nominal 24 V output is not necessarily electrically equivalent to a 27 VDC supply.
⚠️ Check thermal conditions.
A 500 W power supply can dissipate significant heat at partial efficiency. Cabinet ventilation, ambient temperature, mounting orientation, and clearance should be checked before commissioning.
⚠️ Verify the complete material number.
For procurement, use:
ABB LXN 1604-6 — 3BHL000986P7000 — 27V 500W
This avoids confusion with similarly named LXN-series units.
