PULS YR20.242 INTRODUCTION
The YR20.242 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.
In addition to the YR20.242, the YR20.246 is available, which features an automated load sharing
between the connected power supplies and functions
that monitor defects in the redundancy circuit or too
high output currents, which could prevent redundancy,
if one power supply fails.
The YR20.242 utilizes MOSFETs instead of diodes for the
decoupling of the two input channels. This reduces the
heat generation and the voltage drop between the input
and the 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.
