3 SPS.500 Wiring Diagram
Two SPS.500 power supplies can be used together in a redundant
configuration. In a redundant configuration, the ORed output controller acts
like an ideal diode. The power supplies do not share the load so that only one
power supply carries the load. The power supply with the highest output
voltage carries the load. The Bedrock IDE or an OPC UA client can determine
which SPS.500 carries the load by checking the amount of current draw of each
supply.

connected to a workstation running an OPC UA client by way of an Ethernet
switch. Alternatively, the redundant power supplies can be configured to
