Low Loss 20A to 40A DIN Rail Mount Redundancy Module Assists Load Current Balancing

San Diego, CA – April 2019 –

TDK Corporation (TSE 6762) announces the introduction of the DRM40 series DIN rail mount redundancy modules.The two 20A 10V to 30Vdc rated inputs can be connected to provide a 20A redundant configuration, or using the load balancing option, to deliver a 40A output.For capacitive and inductive loads, the DRM40 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 200mV.Applications include industrial process control, factory automation, battery chargers, and test and measurement equipment.

If the input currents are unbalanced, the DRM40 front panel mounted LED is off. When the input voltages are adjusted and the load current is shared equally, the LED is illuminated.In addition, the DRM40 has two isolated DC Good PhotoMOS relays to indicate that each input voltage is between the limits of 10V and 30V.Two front panel mount DC Good LEDs provide visual indication.For cost sensitive applications the DRM40B has identical electrical performance without the current balance and DC Good functions.

The DRM40 series is housed in a compact rugged metal enclosure, with overall dimensions of 35mm x 124mm x 125mm (W x H x D) and is suitable for mounting on TS-35/7.5 and TS-35/15 DIN rails. The operating ambient temperature is -40oC to +70oC with no derating. Both models are safety certified to IEC/EN/UL/CSA 60950-1, IEC/EN/UL/CSA 62368-1, UL 508 and are CE marked for the Low Voltage, EMC and RoHS Directives.

More information and product availability can be obtained on the TDK Product Center, or by calling 800-LAMBDA-4.
