The 560PSU02 1KGT011900R0001 is a high-performance power supply unit (PSU) designed specifically for the ABB RTU560 Remote Terminal Unit system. This module is responsible for converting station battery voltages into the stabilized internal voltages required by the RTU560 subrack and its associated I/O modules. Engineered for utility-grade reliability, the 560PSU02 features robust galvanic isolation and advanced protection circuitry to ensure continuous operation of critical monitoring and control systems in power substations and industrial plants.

Application Fields
The 560PSU02 is a core component in infrastructure-scale control systems:
-
Substation Automation: Powering RTU560 racks used for telecontrol, monitoring, and gateway functions.
-
Grid Management: Ensuring reliable data transmission between distributed energy resources (DER) and the SCADA center.
-
Railway Systems: Powering signaling and traction power control interfaces.
-
Renewable Energy: Supporting the control logic for wind farm and solar plant substations.
Product Instructions
-
Safety Check: Before inserting the 560PSU02, verify that the station battery voltage falls within the 24V–60V DC range. Ensure the input polarity is correct, although the unit includes protection.
-
Installation: Insert the PSU into the designated power supply slot of the 560MPR03 or 560SFR02 subrack. Use the guide rails to ensure the rear DIN-connector aligns perfectly with the backplane.
-
Redundancy Setup: For high-availability applications, two 560PSU02 modules can be used in a redundant configuration. The internal circuitry handles the load-sharing and automatic failover.
-
Wiring: Use the specific screw terminals on the front or rear (depending on subrack type) for the primary DC input. Use at least 2.5mm² wire to minimize voltage drop.
-
Status Monitoring: The “OK” LED on the front panel indicates healthy output voltages. If the “Alarm” LED lights up, it may signify an internal fuse failure or a short circuit in the I/O rack.
Q&A – Frequently Asked Questions
Q: Can I use the 560PSU02 for 110V or 220V DC station batteries? A: No. The 560PSU02 is limited to 60V DC max. For 110V/220V DC inputs, you must use the 560PSU01 version (1KGT011600R0001).
Q: Does the module support “Hot Swapping”? A: Yes, in a redundant configuration, one 560PSU02 can be replaced while the other continues to power the system. However, care should be taken to avoid disturbing the backplane bus during insertion.
Q: Why is my 5.0V output measured as 0V even with the green LED on? A: This usually indicates an overload on the subrack bus. The PSU will enter a “hiccup” mode or shut down specific rails if the total current draw exceeds 12.0 A.
Q: Is there an internal battery in the 560PSU02? A: No. The PSU is a converter only. Real-time clock buffering for the RTU is typically handled by a battery on the CMU (Communication Unit) module, not the PSU.
