PULS SLR02 Diode Redundancy Module

Introduction

The redundancy module SLR02 is designed to create an N+1 redundancy in combination with the PULS 24...28V power supplies units SL10, SL20, or SL30 or other 24...28V power supplies with an output current of up to 30A (max. 35A). One SLR02 is required for two power supply units.

The module decouples the power supply outputs from each other so that in case of failure one power supply unit cannot overload the other power supply units. A relay-changeover contact, picked up under normal conditions and dropped in case of failure, indicates the status of each connected power supply unit. A Single Redundancy Module, the SLR01, is available to design a redundancy with one attached power supply unit and an output current of up to 40A (max. 50A). For smaller current values of 2.5A, 5A and 10A PULS also offers the SLR2, SLR5 and SLR10 power supplies with integrated redundancy modules.
