ABB Power Supply Unit 560PSU01 RTU560 Product Family

Power supply unit for RTU560 racks

- Input voltage: 110.... . 220 V DC

- Output voltage: 5 V and 24 V DC

- Suitable for 560MPR03/560SFR02

Application: Power supply unit 560PSU01 for RTU560 racks

The power supply unit 560PSU01 provides two supply voltages (5 V DC and 24 V DC) for the RTU560 subracks 560MPR03 and 560SFR02.

The output power is sufficient to power up to 4 subracks of communication units (CMUs).

For project configurations with high availability requirements, redundant power supplies can be configured. In this configuration, the two power supply units 560PSU01 operate in parallel mode.

If one of the power supplies fails, they can take over the entire load. Only power supplies of the same type and size can be used for redundant operation.

The power supply unit 560PSU01 is available in the following models (specifications):

- R0002 Input range 110 ... 220 Vdc (-20%... +15%)

Characteristics

The power supply unit 560PSU01 has the following features and functions:

- Potential isolation between input and output

- Natural convection cooling

- Electronic power limitation at the output

- Short-circuit protection at the output

- Overvoltage protection on the inputs

- Reverse voltage protection on inputs

- Parallel operation, monitoring of redundant power supply configurations

- Controlled load balancing in redundant operation

- LEDs for monitoring the output voltage

- Alarm indication in the event of a fault

- Withstands input voltage interruptions of up to 50 ms
