Overview

The MURR 64209426 MPS5-230/24 is a compact switch-mode power supply designed for electrical power distribution in industrial automation systems. The MPS5-230/24 provides a regulated 24 V DC output with a rated output current of 5 A, making it suitable for supplying control circuits, automation components, sensors, interfaces, and other 24 V DC equipment.

The MPS5-230/24 belongs to the MURR Elektronik Power+ range of industrial power supplies. Its electrical configuration is intended for connection to a single-phase AC supply and conversion to a stable DC control voltage. The product is associated with ABB product identification 64209426 in industrial automation and converter-related documentation, while the MURR MPS5-230/24 is also identified by MURR article number 85053 in product references.

With a DIN-rail mounting concept and a compact industrial enclosure, the power supply can be integrated into control cabinets and electrical panels where 24 V DC is required for automation equipment. Its function is centered on reliable voltage conversion and distribution within the control system.

Electrical Characteristics

The MURR MPS5-230/24 accepts an AC input in the 100–240 V range. The input is specified for 50/60 Hz operation, allowing the power supply to be used with common industrial AC supply networks. Depending on the connected supply voltage, the input current varies accordingly.

The DC output is rated at 24 V with a maximum continuous output current of 5 A. This corresponds to a nominal output capacity of approximately 120 W. The 24 V DC output is commonly used as the control voltage in industrial automation equipment, where PLC systems, sensors, relays, communication devices, interface components, and other control elements require a regulated DC supply.

The product information identifies the output as SELV and specifies an IP20 protection rating. These characteristics define the electrical and enclosure conditions under which the power supply is intended to operate. The IP20 enclosure classification is appropriate for installation inside protected electrical cabinets and control panels rather than exposed outdoor environments.

MPS5-230/24 Power Supply Design

The MPS5-230/24 uses switch-mode power supply technology to convert the AC input into a regulated DC output. Compared with traditional linear power supply architectures, a switch-mode design allows the power conversion stage to achieve a compact form factor while supporting the required output capacity for industrial control applications.

The power supply is designed around the requirements of industrial control cabinets. The 24 V DC output can serve as a centralized control voltage source, reducing the need for multiple independent low-voltage power conversion devices within the same cabinet.

DIN-rail mounting simplifies integration into standard control cabinet layouts. The mounting arrangement also allows the power supply to be positioned alongside circuit breakers, terminal blocks, PLC components, relays, communication modules, and other control equipment.

Technical Specifications

Industrial Automation Applications

The MURR MPS5-230/24 is intended for applications in which a stable 24 V DC control supply is required. Industrial automation cabinets frequently use 24 V DC as the operating voltage for PLC systems, I/O modules, control relays, sensors, signal conditioners, communication equipment, and other electronic devices.

In a PLC control cabinet, the MPS5-230/24 can be used as a centralized DC power source for control components. The 5 A output capacity allows multiple devices to be supplied from the same power conversion stage when the total system load remains within the rated output capability.

The unit can also be integrated into machine control systems, process automation equipment, production machinery, material handling systems, electrical control panels, and other industrial installations. Its DIN-rail format makes it particularly suitable for cabinet-based system architecture.

For ABB-related automation and power-conversion equipment, the 64209426 identification is associated with the MPS5-230/24 power supply. This makes accurate identification important when replacing or maintaining equipment in an existing installation.

Installation Considerations

The MPS5-230/24 should be installed inside an appropriate electrical enclosure with adequate ventilation and sufficient clearance around the power supply. The installation environment should comply with the applicable electrical and environmental requirements of the complete control cabinet.

Before installation, the input voltage and frequency should be checked against the available AC supply. The output circuit should also be designed according to the 24 V DC load requirements of the connected equipment. The total continuous load should remain within the rated 5 A output capacity.

Correct wiring of the AC input and DC output terminals is essential. Protective earth and other electrical connections should be implemented according to the applicable installation standards and the documentation for the complete automation system.

Because the device uses an AC mains input, installation and servicing should only be performed by appropriately qualified personnel following the electrical safety procedures applicable to the equipment.

Identification and Replacement

When identifying an MPS5-230/24 power supply, several designations may appear in technical records, equipment lists, or spare-part databases. The MURR model designation is MPS5-230/24, while MURR product references identify the unit as Article No. 85053. The number 64209426 is associated with the ABB product identification used for this power supply in relevant industrial equipment documentation.

For replacement planning, it is therefore important to compare the model designation, electrical ratings, input configuration, output capacity, mounting arrangement, and physical connections rather than relying only on one identification number.

The MPS5-230/24 should be selected for applications requiring the corresponding 24 V DC and 5 A power capacity. Where the power supply forms part of an existing ABB converter or automation assembly, the equipment documentation should also be checked to confirm the applicable spare-part identification.

Maintenance and System Integration

Routine maintenance should include visual inspection of the enclosure, wiring, terminals, ventilation conditions, and surrounding components. Dust accumulation, loose connections, excessive heat, or abnormal operating conditions can affect the performance of electrical power equipment and should be addressed according to the maintenance procedures of the complete system.

During troubleshooting, the AC input should first be verified against the expected supply range. The 24 V DC output can then be checked under the appropriate operating conditions. If the output voltage or system behavior is abnormal, the connected load and downstream equipment should also be inspected before determining whether the power supply itself is responsible for the problem.

Conclusion

The MURR MPS5-230/24 is a 24 V DC industrial switch-mode power supply with a 5 A rated output and approximately 120 W output capacity. Its 100–240 V AC input, 24 V DC output, DIN-rail mounting, and IP20 enclosure make it suitable for control cabinets and industrial automation systems.

For identification purposes, MURR MPS5-230/24 is associated with MURR Article No. 85053, while 64209426 is used as an ABB-related product identification for this power supply in relevant industrial equipment references. Accurate identification of both designations can help engineers and maintenance personnel select the appropriate component for an existing automation installation.
