Redundant module 20 A Dimension Series

12-28 V DC, 2x10 A

  • For N+1 and 1+1 Redundant Systems
  • MOSFET transistors
  • Minimum power loss

Product 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.
