Description of Operation of Fault Redundant PSU

The AMC-400+400RDIP PSU is a Hot-Swap Dual Redundant 400W + 400W power supply, i.e. each PSU module supports a max output of 400W. In normal operation the loading is shared between the two power supply modules but if one of the modules should fail then the remaining active module takes over the full load requirements.

When a module fails an audible alarm is generated; the green Alarm LED starts to flash and the green Status LED on that particular module is extinguished. The audible alarm can be switched off by pressing the Alarm Reset switch. The dual mains inputs are also redundant so if the mains is removed from either of the IEC connectors both PSU modules continue to operate giving an extra degree of protection. Upon one of the PSU modules failing, that module can then be easily removed and substituted with a hot-swap replacement that locks into place.
