Uninterruptible Power Supply, 640 mA, MDRC

Product code: GHQ6310049R0111
Power supply with integrated choke for supplying and monitoring of the KNX system voltage. In order to supply the EIB bus voltage in case of a mains failure, a 12 V DC sealed lead acid battery can be connected to the unit. Via a potential free change-over contact, EIB power supply fault conditions can be transmfitted for further information.

Description

The Uninterruptible EIB / KNX Power Supply produces and monitors the EIB / KNX system voltage. The bus line is decoupled from the power supply with the integrated choke.

The power supply is connected to the bus line with a bus connection terminal. A reset is triggered by press ing the reset push button and lasts for 20 seconds (regardless of the duration of the push button action).

The bus line is disconnected from the power supply and the bus devices connected to this bus line are returned to their initial state. If the line should be disconnected for a longer period, the bus connection terminal must be removed from the power supply.

Up to two 12 V sealed lead acid batteries can be connected as a back-up energy supply for the EIB / KNX system voltage in the event of mains failures.

The batteries are charged via the SU/S 30.640.1 during normal operation. The charging voltage is temperature-controlled using a temperature sensor. If a mains failure occurs, the SU/S 30.640.1 is then supplied by the batteries.

The temperature sensor must always be connected to ensure that the battery is charged correctly! 

A fault in the Uninterruptible EIB / KNX Power Supply is reported and stored via a potential-free change-over contact. The following faults cause a switching operation at the changeover contact: mains failure, battery fault, overvoltage and overload or short circuit.
