FAQ

1. What is the main function of the ABB 560PSU01 R0002?

The ABB 560PSU01 R0002 is a dedicated power supply unit for ABB RTU560 systems. It converts a 110–220 V DC input into the regulated 5 V DC and 24 V DC supply voltages required by RTU560 subrack components. The total available output power is 44.3 W, which is designed to provide power for RTU560 communication units and associated modules. The unit also includes electrical protection, output monitoring, and support for redundant operation. This makes it suitable for remote terminal units used in utility automation, substation control, power system monitoring, and other industrial communication applications where stable DC power is essential.

2. What input voltage does the 560PSU01 R0002 support?

The R0002 version of the 560PSU01 is designed for a nominal input range of 110–220 V DC, with an input tolerance of -20% to +15%. This allows the power supply to accommodate variations in the DC supply used by industrial and utility automation systems. The maximum input current is approximately 0.6–0.3 A across the specified input range, while the starting current can be less than 10 A for a short duration. The R0002 version should not be confused with other 560PSU01 variants that use different input-voltage ranges. When replacing the module, the R0002 designation and order number 1KGT006600R0002 should be verified carefully.

3. What output voltages are provided by the ABB 1KGT006600R0002?

The 1KGT006600R0002 provides two regulated DC outputs: 5.1 V DC and 24 V DC. The 5.1 V output has an allowable range of 5.0–5.3 V DC and can provide up to 5.5 A. The 24 V output has an allowable range of 22.4–26.3 V DC and can provide up to 0.7 A. The residual ripple is specified at no more than 30 mVpp for the 5 V output and 80 mVpp for the 24 V output. These separate supply rails allow the power supply to support different voltage requirements within the RTU560 subrack while maintaining regulated DC power for the connected modules.

4. Can two 560PSU01 R0002 units be used in a redundant configuration?

Yes. The 560PSU01 supports redundant power supply operation, with two compatible power supply units operating in parallel. The redundant configuration uses controlled load sharing and monitoring so that the power supplies can share the system load during normal operation. If one power supply becomes unavailable, the remaining unit can take over the required load within the limits of the system configuration. Only power supply units of the same type and version should be used together for this type of redundant arrangement. Correct wiring, monitoring, and system configuration are important because the purpose of redundancy is to maintain RTU operation if one power supply fails.

5. What protection functions are included in the 560PSU01 R0002?

The 560PSU01 R0002 incorporates several protection functions intended to improve reliability in industrial power supply applications. These include input over-voltage protection, reverse-voltage protection, galvanic isolation between the input and outputs, electronic output power limitation, and short-circuit protection on the outputs. The unit also tolerates input-voltage interruptions of up to 50 ms under the specified conditions. A 3.15 A time-delay fuse is specified for the power supply, while an upstream circuit breaker with a 10 A trip current is recommended for the positive input lead. These protective functions help reduce the risk of damage caused by abnormal input conditions, output faults, and temporary supply disturbances.

6. How should a 560PSU01 R0002 power supply failure be diagnosed?

Troubleshooting should begin by checking the DC input voltage and confirming that it is within the specified range for the R0002 version. Next, inspect the input wiring, fuse, external circuit breaker, supply connector, and RTU560 backplane connection. If the input is correct but one or both output voltages are missing, check the module’s LED indications and determine whether an overload, short circuit, or internal fault may be present. The 5 V and 24 V output voltages should be measured using suitable test equipment and according to the applicable maintenance procedure. If multiple RTU560 modules lose power simultaneously, the power supply or backplane should be investigated first. If only one connected module is affected, the problem may instead be associated with its wiring or load.

7. Does the 560PSU01 R0002 require a cooling fan?

No. The 560PSU01 R0002 uses natural convection cooling and does not require a dedicated cooling fan. This fanless design reduces the number of moving components and eliminates the need for fan maintenance. However, natural convection depends on adequate airflow around the RTU560 rack. The module should therefore be installed in an enclosure that allows heat to dissipate effectively, and ventilation openings should not be blocked. The specified operating temperature is 0°C to +70°C, with a relative humidity range of 5–95% without condensation. Excessive ambient temperature, restricted airflow, dust accumulation, or installation near other heat-generating equipment can increase thermal stress and should be avoided.

8. What should be considered when replacing the ABB 560PSU01 R0002?

Before replacement, verify both the model 560PSU01 R0002 and order number 1KGT006600R0002. The R0002 version is specifically designed for a 110–220 V DC input, so using a different RTU560 power supply version without checking the input requirements is not recommended. Before removing the existing unit, the RTU system should be placed in the appropriate safe maintenance state and the DC supply isolated according to the applicable procedure. Check the input wiring, backplane connector, output connections, and surrounding modules for signs of overheating or electrical damage. After installing the replacement, verify the 5 V and 24 V outputs, LED status, alarm indication, and communication-module operation. If redundant power supplies are installed, confirm that both units are the correct type and that load sharing and redundancy monitoring operate correctly before returning the RTU560 system to normal service.
