Redundancy Modules
Available from stockArticle no.:A106.205
The PULS YR20.242 is an efficient MOSFET redundancy module for 24 to 28 V DC power systems up to 20 A. It enables 1+1 and N+1 redundancy while minimising voltage drop and heat generation through low-loss decoupling. Its compact design and input range of 8.4 to 36.4 V DC make it suitable for critical industrial applications. Equipped with screw terminals for a reliable electrical connection.

Description
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 is featured with an automated load sharing between the connected power supplies and functions which 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 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.
