The 560PSU02 is a robust switching power supply that provides galvanic isolation between the station battery system and the sensitive control electronics. It features comprehensive monitoring capabilities, including an internal “Power Good” supervision signal and a dedicated alarm contact to alert the system of input voltage loss or internal hardware failure.

 

Key Specifications

 

Operational Precautions

• Input Polarity: Verify the DC input polarity at the subrack terminals before insertion; while protected, reverse polarity can lead to fuse failure or extended downtime.
• Redundancy Configuration: In high-availability systems, two 560PSU02 modules can be used in parallel for 1+1 redundancy. Ensure the load sharing is balanced as per the RTU560 system manual.
• Hot-Plugging: While the RTU560 supports modularity, it is recommended to disable the input breaker before removing the PSU to avoid arcing on the backplane connectors.

 

Common Questions Q&A

Q: Can this power supply handle 110 VDC station batteries? A: Yes, the wide input range of 48–220 VDC makes it perfectly suitable for standard 110 VDC and 125 VDC utility battery systems.

Q: Does the module include diagnostic LEDs? A: Yes, the front panel typically features status LEDs indicating “Input OK” and “Output OK” for rapid local troubleshooting.
