Description
ABB 560PSU01 | RTU560 Power Supply Unit
Product Overview
The ABB 560PSU01 is the dedicated power-supply unit for the RTU560 rack architecture. It converts the station’s DC input into the regulated low-voltage rails required by RTU560 communication units and associated rack electronics. The current documented R0002 version accepts 110–220 VDC and provides two outputs: 5.1 VDC for the rack’s electronic circuitry and 24 VDC for the applicable auxiliary load. Its total output capability is 44.3 W, with the 5 V rail rated up to 5.5 A and the 24 V rail up to 0.7 A.
Installed in the 560MPR03 or 560SFR02 rack, the ABB 560PSU01 is part of the RTU560 system infrastructure rather than a general-purpose industrial DIN-rail power supply. The unit connects through the RTU560 48-pole Type F DIN 41612 backplane and is designed to support rack configurations containing communication units and I/O hardware. ABB documentation states that the output capacity is sufficient for a subrack with up to four communication units, subject to the actual system configuration and power budget.
A particularly important procurement issue is the 560PSU01 revision. Historical RTU560 material identifies an earlier R0001 version with a 24–60 VDC input, while the current published ordering information identifies 560PSU01 R0002 / 1KGT006600R0002 with a 110–220 VDC input. Those are not interchangeable simply because both carry the 560PSU01 family designation. For a brownfield replacement, the nameplate and complete ordering code should be checked before the input supply is connected.
Product Introduction
Power failures in an RTU rack are not always caused by the controller or I/O modules. A degraded rack PSU can produce undervoltage, intermittent resets, communication faults, and apparently unrelated module alarms. The 560PSU01 provides the regulated supply rails at the rack level and can be installed as part of a redundant PSU arrangement.
For the currently documented R0002 version, the 110–220 VDC input range and 44.3 W output capacity make it suitable for the corresponding high-voltage DC rack architecture. Older installations require extra care because the R0001 variant used a different input range.

Major Features / Practical Advantages
1. Dual regulated output rails
The 560PSU01 generates both 5.1 VDC and 24 VDC from the rack’s DC input. The 5 V rail is the higher-current output, rated from 0.2 A up to 5.5 A, while the 24 V rail supports up to 0.7 A. This arrangement matches the internal power requirements of the rack rather than simply providing a single generic 24 VDC supply.

2. 44.3 W total output capability
The published total output power is 44.3 W. The actual available power should still be checked against the installed communication units and I/O modules, particularly when the rack configuration has been expanded over time.
ABB documentation specifically describes the unit as having sufficient output power for a subrack with up to four communication units. That is a system-configuration statement, not permission to assume every four-CMU combination has identical consumption.
3. Redundant power-supply operation
Two 560PSU01 units can operate in parallel for higher-availability configurations. The documentation states that the two units can take over the full load if one power supply fails, with controlled load balancing during redundant operation. Only power supplies of the same type and rating should be combined for this configuration.
This is useful in substations and remote-control installations where losing the entire RTU because of a single PSU fault is unacceptable.
4. Electronic output protection
The 560PSU01 includes electronic output power limitation and short-circuit protection. This is important in a modular rack because a fault on a downstream circuit should not automatically be treated as a normal PSU overload without checking the individual rack modules and wiring.
5. Input protection
The documented unit includes input overvoltage protection and reverse-voltage protection. It also specifies an upstream 10 A circuit breaker and a 3.15 A time-delay internal fuse arrangement.
The upstream breaker requirement should be considered part of the installation design rather than assuming the PSU’s internal protection replaces cabinet-level circuit protection.
6. Galvanic isolation
The primary input and secondary outputs are galvanically isolated. This helps separate the rack’s low-voltage electronics from the incoming DC supply circuit and is particularly relevant in substation and industrial DC systems.
7. Natural-convection cooling
The 560PSU01 uses natural convection rather than a cooling fan. That removes a fan-maintenance item from the PSU itself, although cabinet ventilation and rack temperature still matter. The published specification derates output by 2.5% per Kelvin above 50°C, so high cabinet temperature should not be ignored simply because the nominal operating limit extends to 70°C.
8. backplane installation
The PSU uses the rack’s 48-pole Type F DIN 41612 connector and is intended for installation in 560MPR03 or 560SFR02 racks. It is therefore not a conventional standalone PSU that can be wired into arbitrary equipment.
9. Status indication and fault monitoring
Front-panel LEDs provide monitoring of the 5 V and 24 V output conditions, while the PSU includes an alarm indication in the event of a fault. Redundant configurations also use monitoring and controlled load balancing.
10. Critical revision distinction
This deserves its own section because it is an easy procurement error.
Historical ABB documentation identifies:
- 560PSU01 R0001: 24–60 VDC input
- 560PSU01 R0002: 110–220 VDC input
Later/current documentation identifies 560PSU01 / 1KGT006600R0002 as the ordering configuration for the 110–220 VDC version.
Therefore, the generic search term 560PSU01 is not enough when replacing an installed unit. The complete revision/order number should be matched to the station’s DC supply.

FAQ
What is the ABB 560PSU01?
The 560PSU01 is an rack power-supply unit. It converts the station’s DC input into regulated 5 VDC and 24 VDC rails used by the rack electronics. It is installed directly into the backplane.
What input voltage does 560PSU01 use?
This depends on the hardware revision.
The currently documented / 1KGT006600R0002 version uses 110–220 VDC with a -20%/+15% tolerance range. Historical documentation identifies as a 24–60 VDC version.
Do not connect an unknown 560PSU01 to the station supply until the revision is verified.
What are the 560PSU01 output voltages?
The documented unit provides:
- 5.1 VDC, 0.2–5.5 A
- 24 VDC, 0–0.7 A
- 44.3 W total output power
The specified output tolerances are 5.0–5.3 VDC and 22.4–26.3 VDC respectively.
Can I use two 560PSU01 units for redundancy?
Yes. Two compatible 560PSU01 units can operate in parallel for redundant power. The documentation states that each unit can take over the full load if the other fails and that controlled load balancing is used. Use matching PSU types/rubrics for the redundant arrangement.
Can I hot-swap the 560PSU01?
Do not assume unrestricted live removal. The documentation establishes parallel redundant operation and fault takeover, but that is not the same as a universal hot-swap authorization. Whether a PSU can be removed under power depends on the complete rack configuration and the applicable maintenance procedure.
Does 560PSU01 support firmware v3.1?
The 560PSU01 is a power-supply module, not the application processor. Firmware-version questions belong primarily to the installed communication unit and RTU software environment. There is no sound basis for describing the PSU itself as having generic “firmware v3.1 support.”
Can 560PSU01 replace ?
No—not without verifying the station’s DC supply architecture and the exact electrical requirements. The documented input ranges are different: historical documentation specifies 24–60 VDC, while specifies 110–220 VDC. Treating them as interchangeable based only on the 560PSU01 family name is an avoidable engineering error.
What should I check before purchasing a replacement 560PSU01?
For a brownfield replacement, verify:
- Exact / revision.
- Complete ABB ordering number.
- Existing station DC voltage.
- 560SFR02 or 560MPR03 rack type.
- Single or redundant PSU configuration.
- Number and type of installed communication units.
- Total rack power demand.
- Backplane connector condition.
- PSU alarm/LED behavior.
- Nameplate and revision photographs.
Procurement Note
The ABB 560PSU01 should be purchased as an system component, not as a generic 44 W DC power supply. Its backplane connection, output rails, redundancy behavior, and rack-specific architecture are integral to its application.
The biggest procurement risk is the input-voltage revision. If the requested description only says “560PSU01,” do not assume the electrical version. Older documentation shows an 24–60 VDC variant, while the currently documented is 110–220 VDC. Confirm the complete nameplate/order number before installation.
For new-surplus or previously installed stock, request photographs of the front label, revision marking, connector area, and PCB condition. A basic output-voltage test is useful, but it should be performed with the correct test procedure and load. For redundant applications, verify that the two PSUs are the same type/rubric before treating them as a matched pair.
