Product information

Description

The MDT STR-0640.01 redundant bus power supply module is a compact DIN-rail device with a 6TE housing that provides a stabilized 640 mA output for bus-powered devices in building automation systems. Designed to support KNX/automation installations, the module supplies a reliable secondary feed to protect against single-source failure and maintain operation of connected sensors, actuators and control units. The housing and mounting format allow easy integration into standard distribution cabinets.

Advantages

The module offers redundant supply capability to increase system availability by providing a backup power source for the bus. Its 6TE width and DIN-rail mounting enable space-efficient installation within electrical panels. The unit delivers a stable 640 mA output appropriate for numerous bus devices and is intended to work seamlessly with typical KNX and building control components, reducing the risk of disruption from a single power supply fault.

Suitable for

KNX and building automation systems requiring backup bus power
Distribution cabinets and DIN-rail installations with limited space
Environments where uninterrupted operation of sensors, actuators and control units is critical

Key specifications

Output current: 640 mA
Mounting: DIN-rail (6TE width)
Function: redundant bus power supply / backup feed for bus-powered devices
Compatibility: designed for use with bus-based automation and control devices
Form factor: compact module suitable for standard electrical distribution panels

How to use

Install the module on a standard DIN rail within the distribution cabinet, ensuring correct orientation and secure mechanical fixation. Connect the module to the bus and to the primary power supply according to the system wiring plan and local electrical regulations. Use the module as a secondary or redundant feed in parallel with the main power source so that connected bus devices remain powered if the primary supply fails. Verify connections and system behavior after installation and perform routine checks to confirm redundancy functionality.

Usage recommendations

Place the module in a dry, ventilated electrical cabinet and avoid mounting near heat sources. Follow manufacturer instructions for wiring and observe local safety and installation standards. Periodically inspect terminals and contacts for secure connections and test redundancy by simulating primary supply loss to confirm continuous operation of critical bus devices.
