ABB 560PSU02

The ABB 560PSU02 is a power supply unit associated with ABB's RTU560 remote terminal unit product family, used in industrial automation and power system monitoring applications. It is designed to provide the power required by compatible control and communication equipment, helping maintain stable operation of remote monitoring and control systems.

Within an RTU560 installation, the power supply subsystem supports the operation of the system's electronic modules and associated components. Its suitability depends on the specific hardware configuration, power requirements, and installation arrangement.

The 560PSU02 is relevant to applications requiring dependable power for remote data acquisition, electrical substation automation, and industrial control infrastructure.

2. Technical Parameters

The specifications above describe the 560PSU02 R0001 version. Output loading and operating-temperature limits must be considered together, as the rated output power may require derating at elevated temperatures.

3. Product Features

Wide DC Input Range

The 560PSU02 accepts a DC input range of 48–220 V, making it suitable for compatible power supply arrangements commonly used in substation automation and remote terminal unit installations.

Dual DC Outputs

The unit generates 5 V DC and 24 V DC supply rails for compatible RTU560 communication units and internal electronic circuits.

Redundant Power Supply Support

Two compatible 560PSU02 units can operate in parallel in supported configurations. If one unit fails, the other can take over the required load, helping improve system availability.

Electrical Isolation and Protection

Input-to-output isolation helps separate the incoming power circuit from the supplied electronics. The design also includes input reverse-voltage protection and output protection functions.

Natural Convection Cooling

The module uses natural convection rather than requiring a dedicated cooling fan, reducing the number of moving parts and simplifying maintenance.

Compact Modular Construction

Its rack-compatible design supports installation and replacement within suitable RTU560 subracks, making it practical for routine servicing and system refurbishment.

4. Structural Composition

The ABB 560PSU02 power supply unit consists of several functional sections:

1. DC Input Circuit: Receives the incoming station DC supply and provides the necessary input protection.

2. Power Conversion Circuit: Converts the input voltage into the regulated DC levels required by the connected RTU560 equipment.

3. Output Regulation Circuit: Maintains the 5.1 V DC and 24 V DC output rails within their specified operating ranges.

4. Protection Circuitry: Helps protect the module and connected equipment against abnormal electrical conditions.

5. Isolation Section: Provides electrical isolation between the input and output circuits.

6. Monitoring and Status Indication: Supports power-supply status observation and fault identification through the unit's designated indicators and system configuration.

7. Mechanical Assembly: Uses a printed circuit board and a compatible rack-mounted format for installation within the RTU560 system.

5. Application Fields

Electrical Substation Automation

The 560PSU02 supplies compatible RTU560 equipment used for substation monitoring, control, and remote data collection.

Power Grid Monitoring

It supports remote terminal units that collect operational information from electrical equipment and communicate with supervisory control systems.

Industrial Process Automation

In suitable configurations, the module can support remote monitoring and control infrastructure in industrial facilities where RTU560 equipment is deployed.

SCADA and Telecontrol Systems

The unit provides the internal power required by compatible communication units involved in transferring field information between remote installations and central control rooms.

Critical Infrastructure Maintenance

As a replacement component, the 560PSU02 is relevant to maintenance, repair, and refurbishment projects involving existing RTU560 installations.

6. Conclusion

The ABB 560PSU02 (1KGT011900R0001) is a dedicated power supply unit for the ABB RTU560 platform. Its principal functions include converting a wide-range DC input into 5.1 V DC and 24 V DC outputs, supplying compatible communication units, and supporting redundant power configurations.
