The DRM40 series DIN rail mount redundancy modules are two 20-A 10- to 30-Vdc-rated inputs that can be connected to provide a 20-A redundant configuration or, using the load-balancing option, to deliver a 40-A output. For capacitive and inductive loads, the module will support an additional 50% peak load for four seconds. The use of low-loss MOSFET reverse current protection devices reduces the internal voltage drop to just 200 mV. If the input currents are unbalanced, the front panel-mounted LED is off. When the input voltages are adjusted and the load current is shared equally, the LED is illuminated.
