OR50 is a modern, CPU controlled device and responds to a wide range of applications where strong redundancy of DC
power supplies is needed.
By keeping the 2 power supplies (PS) “hot” (each operating at half of the load need) the system reaches higher MTBF than by
using one PS “hot” and the other “cold” (as per standard ORing devices).
It allows same life expectancy for the electrolytic
capacitors and other sensitive parts of both PS and it prevents an excessive ageing of the unit that should be kept “hot”.
OR50 allows the paralleling of the output of any 2 identical PS with any current up to 50A and voltages from 12V to 85V.
isolation between the units is achieved through power MOSFETs with advanced control circuitry.
Several OR50 can be interconnected in order to achieve redundancy for > 2 PS systems.
OR50 allows perfect current distribution between 2 PS, in case of their use for shared power. OR50 provides perfect isolation between 2 PS in case of 1 unit failure and also the continuous delivery of energy towards a
critical load. It is specially designed for high MTBF and compliance to a wide choice of PS and loads.
