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.
