EMERSON SolaHD SDN2X line of power supply redundancy modules boost operational reliability and ensure additional protection against critical power failures in hazardous locations and harsh industrial environments. Products continuously monitor two power supplies connected in parallel. In the event one power supply fails, unit automatically changes over to the second power supply, eliminating the potential for single power supply failure causing an unexpected shutdown resulting in costly system downtime. Because the power supplies are decoupled via the module, the operating power supply doesn’t feed into the failed power supply.
