YR40.482
Redundancy Modules
Available from stockArticle no.:A105.087
The PULS YR40.482 is an efficient MOSFET redundancy module for 24 to 56 V DC power systems up to 40 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 20.4 to 64.4 V DC make it suitable for critical industrial applications. Equipped with screw terminals for a reliable electrical connection. Marine approvals support use in marine and offshore environments.

Description
The YR40.482 is a redundancy module, which can be used to build 1+1 and N+1 redundant system. It is equipped with two input channels, which can be connected to power supplies with up to 20A output current and one output, which can carry nominal currents up to 40A.
The novelty of this redundancy module is the utilization of 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 46mm 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.
