ABB Power Supply Unit 560PSU02 Power supply unit for RTU560 racks

Power supply unit for RTU560 racks

- Input voltage: 48.... Input voltage: 48...220 VDC

- Output voltage: 5 V and 24 V DC

- For 560MPR03/560SFR02

Power supply unit 560PSU02

The power supply unit 560PSU02 provides two supply voltages (5 VDC and 24 VDC) for the RTU560 subracks 560MPR03 and 560SFR02.

The output power is sufficient to power subracks with up to 8 Communication Units (CMUs).

For project configurations with high availability requirements, redundant power supplies can be configured. In this configuration, two 560PSU02 power supply units 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 560PSU02 is available in the following models (specifications):

- R0001 Input range 48 ... 220 V DC (-20%... +20%)
