PS1000-D2-24.20.RM – Redundancy Module with
Automated Load Sharing
The redundancy module is a dual redundancy module,
which can be used to build 1+1 redundant systems.
The device is equipped with two input channels, each rated
for 10A for ambient temperatures up to +70°C and are
individually decoupled by utilizing MOSFET technology.
The inputs can also be operated up to 12A when the
ambient temperature does not 45°C.
The output can be loaded with nominal 20A at +70°C or 24A
at 45°C continuous current.
Using MOSFETSs instead of diodes reduces heat
generation, losses and voltage drop between input
and output. Due to these advantages, the unit is very narrow
and only requires 32mm width on the DIN mounting rail.
The device does not require an additional auxiliary voltage
and is self-powered even in case of a short circuit across
the output.
The device is equipped with an automated load sharing feature, which balances the load
current between the two input channels. It also monitors the function of the redundancy
circuitry and provides a signal if the output current is too high, which could prevent redundancy
if one power supply fails. The signal also reports too low or too high input voltages.
See chapter 25.5 for wiring information.
