DRM40 Series Redundancy Modules

TDK Corporation's DRM40 series DIN rail mount redundancy modules offer two 20 A, 10 V to 30 VDC-rated inputs which can be connected to provide a 20 A redundant configuration. Alternatively, using the load-balancing option, these modules can deliver a 40 A 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 200 mV.

If the input currents are unbalanced, the DRM40 front panel-mounted LED is turned 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 10 V and 30 V. 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 35 mm x 124 mm x 125 mm (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 -40°C to +70°C 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.
