MEAN WELL DRDN-20/40 and ERDN-20/40 Series Redundancy Modules are used with a backup power supply to improve overall system operation reliability. These modules feature 5V (ERDN20 only) /12V/24V/48V input voltage for selection, support for N+1 and 1+1 redundancy systems, built-in two rails DC input contacts, and a single output. The DRDN-20/40 and ERDN-20/40 modules adopt MOSFET technology to reduce heat loss and the voltage difference between input and output voltages. These modules operate from -40°C to 80°C ultra-wide temperature range. https://elecena.pl/product/19544207/isolated-dc-dc-converter-20a-5vdc-redundancy-module 2021-09-29 https://elecena.pl/product/19544207/isolated-dc-dc-converter-20a-5vdc-redundancy-module 2022-01-11 https://elecena.pl/product/19544207/isolated-dc-dc-converter-20a-5vdc-redundancy-module 2022-03-29 https://elecena.pl/product/19544207/isolated-dc-dc-converter-20a-5vdc-redundancy-module 2022-05-26 https://elecena.pl/product/19544207/isolated-dc-dc-converter-20a-5vdc-redundancy-module 2022-08-07
