Functional description:
The uninterruptible KNX/EIB power supply 640 mA (USV) generates and monitors the KNX/EIB system
voltage. The power supply is designed to ensure the interruption-free supply of max. 64 bus devices (1
line) directly via the integrated choke and is therefore suitable for use especially in KNX/EIB security
systems. The device is connected to the system by means of the bus connecting terminal at the front of
the device (no data rail required). The bus output is overload- and short-circuit-protected in acc. with the
KONNEX specification and offers protection against overvoltage.
The KNX/EIB voltage can be buffered with a 12 V DC gelled lead-acid storage battery which is connected
to the device by means of a pre-assembled 4-wire connecting cable. When the mains voltage is on, the
storage battery is recharged via the uninterruptible power supply in a temperature-controlled mode. In
case of mains voltage failure, the KNX/EIB power supply and with it all connected bus devices are
supplied with power from the storage battery. To increase the buffering time during a mains failure, a
second storage battery can be connected to the system with a pre-assembled 2-wire connecting cable.
Storage batteries and cable sets must be ordered separately as accessories.
A potential-free change-over contact can be employed for fault signalling puposes in the event of mains
failures, battery trouble, overvoltage / overloading and short-circuits. Up to 5 different LEDs on the front of
the device inform the user about the different states of operation of the power supply.
