ABB 560PSU01 1KGT006600R0002 Power Supply Module

Configured for regulated DC power conversion in ABB RTU560 systems, the ABB 560PSU01 (560PSU01 Power Supply Module) provides isolated +5 V DC and +24 V DC outputs for RTU560 subracks including 560MPR03 and 560SFR02. The unit supports parallel redundant operation with controlled load sharing and can supply up to four communication modules.

Hardware Specifications

RTU560 Power and Redundancy Characteristics

The 560PSU01 accepts 110-220 VDC input and generates +5 VDC and +24 VDC supply rails for RTU560 subrack hardware. Galvanic isolation separates the input and output circuits. Electronic power limitation and short-circuit protection limit abnormal output conditions.

Two 560PSU01 units can operate in parallel with controlled load sharing for redundant power configurations. The supplied data specifies tolerance of input interruptions up to 50 ms. LED indicators provide local voltage and fault status indication.

The fanless natural-convection design eliminates forced-air cooling requirements. Installation must therefore maintain sufficient airflow around the module and avoid obstruction of the natural convection path.

Frequently Asked Questions

Q: Can two 560PSU01 units operate in parallel?

A: Yes. The modules support parallel operation with controlled load sharing for redundant power supply configurations.

Q: What DC output voltages are provided?

A: The module provides +5 VDC and +24 VDC outputs for RTU560 subrack equipment.

Q: What protection functions are specified?

A: The supplied data specifies galvanic isolation, short-circuit protection, electronic power limitation, input over-voltage protection, reverse polarity protection, and tolerance of input interruptions up to 50 ms.

Field Installation Guidelines

• Install the module in the specified RTU560 subrack position and verify mechanical engagement before energizing the system.
• Confirm that the applied DC input voltage is within the specified 110-220 VDC range, including the stated input tolerance.
• Verify the polarity of the DC input wiring before applying power.
• Keep power wiring separated from low-level communication and signal wiring where practical to reduce conducted and radiated interference.
• Bond cable shields according to the RTU560 system grounding design and applicable site electrical standards.
• Maintain unobstructed space around the module for natural-convection cooling.
• For redundant configurations, verify correct parallel wiring and controlled load-sharing configuration before placing both power supply units under load.
• After energization, check the module LEDs for voltage and fault status and verify the +5 VDC and +24 VDC supply rails at the intended subrack interface.
• Do not perform wiring changes on energized circuits unless the applicable RTU560 installation procedure explicitly permits the operation.
