KNX Bus Power Supply 640 mA

Code: EK-AB1-TPPhase Out

Description

The Ekinex® 640 mA KNX bus power supply supplies and monitors the 30 Vdc voltage required by the KNX bus for operation. An integrated choke provides for decoupling power supply and bus line.

On a bus line powered by a 640 mA power supply unit may be connected a maximum of 64 bus devices. Output is protected from overload and short-circuit.

Delivery includes one terminal block for connection to the bus.
