KNX power supplies

Gira KNX power supply 640 mA with 2 integrated chokes

KNX power supply 320 mA with integrated choke

The power supply 320 mA with integrated choke has one unchoked and one choked output. The unchoked output can be used to supply another line or for function devices (e.g. SmartSensor) that require an auxiliary voltage. Any desired load distribution on the outputs (choked or unchoked) is possible, however the total rated current of 320 mA may not be exceeded. The outputs are equipped with shared overload or short-circuit protection. Connection is made via KNX bus connection or branch terminals. A data rail is not required in this respect.

KNX power supply 640 mA with 2 integrated chokes

The same product features apply for the power supply 640 mA with 2 integrated chokes as for the KNX power supply 320 mA with integrated choke. However, in addition to one unchoked output, it also has two choked outputs.

KNX power supply 640 mA uninterruptible

The uninterruptible power supply 640 mA is equipped with an integrated choke to decouple the bus line from the power supply. It also has connections for a lead-gel rechargeable battery to buffer the KNX voltage in case of mains failure. Up to two lead-gel rechargeable batteries can be connected and charged via the uninterruptible power supply. The charging voltage is controlled on the basis of temperatures using a temperature sensor. The uninterruptible power supply has a potential-free changeover switch for reporting a fault (e.g. mains failure, battery failure, overload or short circuit). Connection is made via KNX bus connection or branch terminals. A data rail is not required in this respect.

Power supply

The power supply for the weather station and the built-in heating of the wind sensor 1-10 V can be used as a DRA device for the rain sensor 0/10 V and similar components from the Gira product range.
