Power Supply of Ballasts
Electronic ballasts with 1-10V control input usually cannot be shut down via conrol voltage. To power off
the ballasts, the 3044B-H features four switched power outputs (connectors CN8-CN11). Power will be
cut of when the associated DMX control input is driven with 000 control value. The output will be activated
for DMX data 001 thru 255 (01 hex to FF hex).
Schematic: individually powered and
switched ballasts
Schematic: heavy load switched by
additional contactor (use 230V AC relay, if
necessary, bypass with 0.22uF capacitor)
Schematic: ballasts not switched, powered
directly from mains
