ABB 3BHL000986P7002 LWN2660-6E Power Supply Module

The ABB 3BHL000986P7002, associated with the LWN2660-6E type designation, is an industrial power supply module designed to provide regulated DC power for electronic and automation equipment. The unit belongs to the LWN series of AC/DC power conversion products and is identified in technical component records as a power supply. Its electrical architecture is based on a wide-range AC input and two individually regulated DC output channels, making it suitable for control systems where stable auxiliary power and electrical separation are important.

For industrial automation applications, the power supply is an important part of the overall control infrastructure. Controllers, interface electronics, instrumentation, communication equipment and other electronic loads require a consistent DC supply to operate within their specified electrical limits. The ABB 3BHL000986P7002 addresses this requirement through two isolated output channels. Each output is specified at approximately 24.7 VDC with a maximum output current of 5 A, providing a practical power source for multiple DC loads within an industrial electrical cabinet.

ABB 3BHL000986P7002 Product Identification

The main product identification is 3BHL000986P7002, while LWN2660-6E is the associated type designation. Technical catalog records identify the product as a power supply, and related component information also associates the unit with the LWN2660 series. When selecting this component for an existing installation, the complete part number should be used because ABB equipment often contains several closely related versions with different electrical configurations.

The identification of the exact type is particularly important when replacing a power conversion unit in an established automation system. Input voltage, output configuration, current capability, mechanical dimensions and terminal arrangement should all be compared with the requirements of the installation. The part number provides the most direct reference for matching the required unit with system documentation and electrical drawings.

Input and Output Characteristics

The LWN2660-6E uses a wide AC input range of approximately 85 to 264 VAC, allowing the power supply to accommodate a broad range of industrial AC supply conditions. This wide input capability is useful in control panels that may operate with different nominal supply voltages. The power conversion stage is designed to transform the incoming AC supply into regulated DC power for connected electronic loads.

The output section contains two electrically isolated and individually regulated outputs. Each output provides approximately 24.7 VDC at up to 5 A. The dual-output arrangement allows different groups of control equipment to be supplied through separate output channels. Electrical isolation between the outputs can also help simplify power distribution in systems where separate DC circuits are required.

The combined power capability is approximately 250 W. Actual system loading should always be evaluated against the applicable technical documentation, wiring arrangement and environmental conditions. Keeping the connected load within the specified electrical limits is important for maintaining the intended operation of the power conversion system.

Power Factor Correction and Electrical Isolation

One notable characteristic of the LWN2660-6E is its power factor correction capability. PFC technology is used to improve the relationship between the input current and the applied AC voltage, helping the power supply operate more effectively from the upstream electrical network. In industrial installations containing multiple electronic power supplies, power factor characteristics can be an important consideration when evaluating the overall electrical load of a control cabinet.

The output circuits are electrically isolated, with technical component information specifying an isolation voltage of approximately 2.8 kV. Isolation is particularly relevant in industrial control architectures because it helps separate the input power domain from the DC output circuits. It also provides an additional electrical barrier between independent output channels and can support cleaner power distribution for sensitive electronic equipment.

Mechanical Design and Installation

The LWN2660-6E is associated with industrial DIN rail power supply applications. Its published dimensions are approximately 113.6 mm in length, 103 mm in width and 138 mm in height. The mechanical format allows the power supply to be integrated into control cabinets and electrical enclosures where DIN rail mounting is used.

When installing the 3BHL000986P7002, adequate space should be maintained around the power supply according to the applicable installation documentation. Clearance is important because power conversion generates heat during operation. Proper cabinet ventilation, suitable conductor sizing and correct terminal connections should be considered when designing or servicing the installation.

Operating Environment

The published operating temperature range for the LWN2660-6E is approximately -40°C to +60°C. This range allows the power supply to be considered for a broad variety of industrial environments. Nevertheless, actual operating conditions depend on cabinet temperature, connected load, ventilation, installation position and other system-level factors.

The power supply uses a design intended for industrial electrical applications and incorporates features associated with modern AC/DC conversion. Its combination of wide input voltage, dual regulated outputs, power factor correction and electrical isolation provides a useful architecture for control and instrumentation power distribution.

Application in Industrial Automation Systems

The ABB 3BHL000986P7002 can be applied wherever regulated DC power is required within an industrial electrical system. Typical applications include control cabinets, automation panels, electronic instrumentation assemblies and auxiliary power circuits. The 24.7 VDC output level is suitable for many industrial electronic loads that operate around the 24 VDC control-voltage standard.

In a control cabinet, the two output channels can be used to organize DC power distribution between different groups of equipment. For example, one output may supply a group of control electronics while the second output supplies another isolated group. The exact allocation depends on the electrical design of the installation and the current requirements of the connected devices.

The unit can also be relevant in systems containing industrial controllers, interface devices, monitoring electronics and other low-voltage control equipment. Because the power supply is part of the electrical infrastructure rather than the application controller itself, its role is to provide the stable DC energy required by those downstream devices.

Selection and Replacement Considerations

When selecting the ABB 3BHL000986P7002 for an existing system, engineers should verify the complete part number, type designation, input voltage requirements, number of outputs, output voltage, output current, mechanical dimensions and installation method. These details are more important than relying only on a general description such as “24 V power supply,” because industrial power supplies with similar nominal ratings can have different output configurations and physical interfaces.

It is also useful to compare the technical documentation of the installed unit with the replacement component before installation. Particular attention should be given to terminal assignments, grounding requirements, load distribution between outputs and cabinet ventilation. Where an installation uses multiple power supplies in parallel or redundant configurations, the system design should be checked carefully before changing the power architecture.

Technical Summary

Conclusion

The ABB 3BHL000986P7002 LWN2660-6E is an industrial AC/DC power supply designed around a dual-output architecture. Its wide 85–264 VAC input range, two isolated 24.7 VDC outputs, 5 A output capability per channel, power factor correction and industrial temperature range make it suitable for a variety of control and automation power applications. The product is best understood as a power conversion component within an industrial electrical system, supplying regulated DC power to downstream control and electronic equipment.

For system integration, maintenance or replacement work, the complete ABB part number 3BHL000986P7002 and type designation LWN2660-6E should be referenced together. Verifying electrical ratings, terminal configuration, mounting requirements and system load conditions before installation helps ensure that the selected power supply matches the intended application and existing control architecture.
