DRM40 | Out of Stock - Please contact our Office | 10-40V | $139.00 |
The DRM40 series of 20 to 40A DIN rail mount redundancy modules can be used in N+1 redundancy applications or to parallel two power supplies for additional power. The DRM40 has a current balancing LED indicator which is illuminated when both power supplies have been adjusted to deliver the same current. Two isolated alarm signals indicate the output voltage status of each power supply.
Two 10V to 30Vdc inputs are rated at 20A each and the output at 40A. A 150% peak load capability for four seconds is provided for capacitive and inductive loading. The internal MOSFET reverse current protection devices have a low 200mV drop, reducing voltage losses in the module. An LED on the front panel provides a visual indication when both input currents are balanced and equally sharing the output load. Applications for the DRM40 modules include factory automation, process control and test and measurement equipment where two power supplies are used in a redundant configuration, paralleled to obtain higher power or for battery charging purposes.
In addition to two front-mounted LEDs, the DRM40 has two isolated DC Good PhotoMOS relays to remotely monitor the presence and status of each input voltage. For cost-sensitive applications, the DRM40B model provides the same reverse protection functionality, without the DC Good and current balancing circuitry.
The DRM40 series is housed in a metal enclosure, measuring 124mm in height, 125mm deep and a width of 35mm. The modules are rated for full load operation in -40°C to +70°C ambient temperatures. Both units are safety certified to IEC/EN/UL/CSA 60950-1, IEC/EN/UL/CSA 62368-1 and UL 508, and CE marked for the Low Voltage, EMC and RoHS Directives.
