Schneider KNX REG Emergency Power Supply (MTN683901)

Description

Introduction

The Schneider MTN683901 is a specialized KNX REG emergency power supply unit engineered to provide power buffering for KNX system networks. Designed for standard DIN rail installation across 4 modules of 18 mm each, this light grey component ensures uninterrupted system operation by buffering the KNX bus voltage during mains electricity outages. This device is part of our KNX automation components range.

Operating at a network frequency of 50 to 60 Hz with a 230 V AC output voltage, this device prevents bus communication failure in smart building automation setups. Integrated LED signaling offers immediate visual status feedback for installers and integrators directly on the panel front.
