Description
Product Overview
The ABB LWN2660-6E 3BHL000986P7002 is an industrial power-supply module intended to provide regulated DC auxiliary power within ABB equipment. ABB catalog information identifies the unit specifically as “POWER SUPPLY, LWN2660-6”, with product ID 3BHL000986P7002 and ABB type designation LWN2660-6E. Secondary technical records identify it as a 24 V, approximately 250 W AC/DC converter, which is consistent with the product’s power-supply classification.
For maintenance teams, the ABB LWN2660-6E 3BHL000986P7002 should be regarded as a power-conversion component rather than a PLC or DCS I/O module. Its job is to maintain the DC supply required by downstream control, interface, or power-electronics circuits. That makes output stability, input compatibility, terminal arrangement, cooling, and protection behavior more important than software or firmware compatibility. A replacement therefore needs to match the complete electrical and mechanical configuration—not simply the nominal 24 V output.
The ABB LWN2660-6E 3BHL000986P7002 is also associated in secondary documentation with ABB power-system and converter equipment, although some web listings incorrectly describe it as an ACS6000 DC-link converter or a high-voltage drive front-end. Those descriptions should not be accepted without the original cabinet documentation. ABB’s catalog-derived entry is much more specific: LWN2660-6E is a POWER SUPPLY, with tariff classification 85044090. This distinction is important because a DC-link converter and a 250 W auxiliary power supply are completely different maintenance items.

The 24 V / 250 W description is supported by available product records, including a catalog record identifying the unit as an ABB power supply and a technical listing specifying “24 V, 250 W, AC-DC CONV +/-.”
Specification caution: Several secondary listings claim that this unit provides two independent 24 V outputs, while another source describes a dual-output ±24 V arrangement. Those claims are not sufficiently supported by ABB’s accessible catalog record. For procurement, the actual terminal marking and original ABB wiring documentation should determine whether the installed version is single-output, dual-output, or another configured arrangement.

Frequently Asked Questions
1. What is ABB 3BHL000986P7002 used for?
It is an ABB industrial power supply intended to provide regulated DC auxiliary power to equipment circuits. ABB’s catalog-derived record explicitly identifies the product as POWER SUPPLY and gives as the type designation.
It should not be confused with an ABB controller, I/O module, or high-power converter semiconductor.
2. Is the a 24 V, 250 W power supply?
Available records support that description.
A technical product record identifies 3BHL000986P7002 as “24 V, 250 W, AC-DC CONV +/-,” while ABB catalog information identifies the part as a power supply.
The exact output current and terminal arrangement should still be confirmed from the unit nameplate before applying the full rated load.
3. Can I replace with LWN2660-6EG?
Do not assume a direct replacement based solely on the model suffix.
Some secondary documentation identifies LWN2660-6EG as a newer replacement for , but the available evidence does not provide enough ABB documentation to certify universal pin-for-pin interchangeability.
Before substitution, compare:
- Input voltage
- Output voltage
- Output current
- Terminal layout
- Mechanical dimensions
- Mounting arrangement
- Protection behavior
- Cabinet wiring
4. Can I hot-swap this power supply?
Do not treat it as hot-swappable.
Even if the supply feeds redundant or isolated circuits, removing an energized power module can expose personnel to hazardous voltage and can interrupt downstream control electronics.
A controlled replacement should include power isolation, stored-energy verification, terminal identification, replacement, insulation/connection checks, and controlled re-energization.
5. Will replacing 3BHL000986P7002 erase PLC or DCS logic?
No—the power supply itself does not normally store the PLC/DCS application program.
The real concern is the equipment it powers. If the supplies controller electronics, communication hardware, or drive-control circuits, loss of auxiliary power can cause those devices to restart or enter a fault state.
Before replacement, document the affected equipment and confirm that its configuration is retained.
6. Does require firmware v3.1?
No firmware version should be assigned to the power supply based on the model number.
This is a hardware power-conversion device. Compatibility is primarily electrical and mechanical: input, output, terminal assignment, load capacity, protection, and physical installation.
7. How should I verify a New Surplus ?
For a new-surplus unit, I would verify:
- nameplate
- 3BHL000986P7002 part number
- ABB identification label
- Input-voltage rating
- 24 V output rating
- Rated power
- Terminal configuration
- Physical dimensions
- Connector/terminal condition
- Capacitor condition
- Insulation resistance where appropriate
- No corrosion or storage damage
- Controlled output-voltage test before installation
One procurement warning: some secondary listings describe this part as a high-voltage DC-link supply for an ACS6000. That description is not consistent with ABB’s catalog classification of / 3BHL000986P7002 as a POWER SUPPLY. For a critical replacement, use the ABB part number and the original cabinet documentation as the final identification basis.
