Power consumption, typically 50 Hz (400 Hz) EDS44...-L ≤4 W / 7 VA (≤4 W, 28 VA)
Power consumption, typically (DC via BB bus) EDS44...-S ≤1 W
1) At a frequency > 200 Hz, the connection of X1 and k1-12/l1-12 must be insulated. Only permanently installed devices
which at least have overvoltage category CAT2 (300 V) may be connected.
2) Only 50/60 Hz are permitted for UL applications.
