GENERAL 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.

ZM11.SIDE - SIDE MOUNTING BRACKET This bracket is used to mount the YR20.242 redundancy module sideways with or without utilizing a DIN-Rail. The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the steel brackets can be mounted. For sideway DIN-rail mounting, the removed aluminum brackets and the black plastic slider need to be mounted on the steel bracket. Fig.

USING ONLY ONE INPUT INSTEAD OF BOTH CHANNELS Using only one input instead of both is allowed up to a nominal input current of 24A (at max. +45°C ambient temperature) or 20A (at max. +70°C ambient temperature). However, it is always recommended to connect both input path in parallel for reduced power losses and voltage drop.

RECOMMENDATIONS FOR REDUNDANCY Recommendations for the configuration of redundant power systems: - Use separate input fuses for each power supply. - Use three-phase power supplies to gain additional safety if one phase fails. - When single-phase power supplies are utilized connect them to different phases or mains circuits if possible.

MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
