LDX-D50 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”.

LDX-D50 allows the paralleling of the output of any two identical PS

with any current up to 50 A and voltages from 12 V to 85 V. The

isolation between the units is achieved through power MOSFETs with

advanced control circuitry.

Several LDX-D50 can be interconnected in order to achieve

redundancy for > 2 PS systems.

LDX-D50 allows perfect current distribution between 2 PS, in case of

their use for shared power.

LDX-D50 provides perfect isolation between 2 PS in case of one 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.
