GIRA KNX Power supply 640 mA uninterruptible

Available for 3-5 working days Delivery


The uninterruptible power supply 640 mA generates the KNX system voltage.
With integrated choke for de-coupling the bus line from the power supply.
With connections for a lead-gel rechargeable accumulators for buffering KNX voltage in case of a mains failure.
Up to two lead-gel rechargeable accumulators can be connected and charged via the uninterruptible power supply.
The charging voltage is controlled depending on the temperature using a temperature sensor.
The uninterruptible power supply has a zero-voltage 2-way switch for reporting a fault (e.g. mains failure, battery failure, overload, or short circuit).
