ENERAL ESCRIPTION
The YR20.246 is a redundancy module for building
redundant power supply systems. It is equipped with
two input channels and one output. The two inputs are
decoupled by MOSFET technology.
The device is equipped with an automated load sharing
feature, which can compensate a small voltage
imbalance between the power supplies connected to
the inputs in order to achieve an even current share. It
also monitors the function of the redundancy circuitry
and provides a signal in case of a failure or a high
output current, which could prevent redundancy if one
power supply fails. If this feature is not required the
YR20.242 is available.
The redundancy utilizes MOSFETs instead of diodes for
the decoupling of the two input channels. This reduces
the heat generation and the voltage drop between
input and output. The redundancy module does not
require an additional auxiliary voltage.
Due to the low power losses, the unit is very slender and
only requires 32mm width on the DIN-rail. Large
connection terminals allow for a safe and fast
installation. The large international approval package
makes this unit suitable for nearly every application.
