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. The EK-AG1-TP version is provided with an additional 30 Vdc output
can be used as auxiliary power supply for other devices requiring SELV voltage
(Safety Extra Low Voltage). The total current provided by the two outputs (KNX bus
line and auxiliary power supply) cannot exceed 640 mA. The device supports short
network voltage interruptions (max. 200 ms).
