KNX BUS device|KNX BUS power supply|LMK-640A
Profile
● This KNX power supply unit provides and monitors the operating voltage for EIB/KNX systems.
● Its output features two sets of terminals: one for EIB bus power and signal transmission, and the other for auxiliary power output.
● Operating on 30 V DC, the unit includes a built-in choke (reactor).
● When an external choke is connected to the auxiliary power terminals, this output can also function as a bus power supply while retaining signal transmission capability.
Features
●Rated current of EIB and auxiliary power output 640 mA, short-circuit protection
●With reset reset button (for EIB/KNX power supply re-output)
