Products description

The standard control voltage for electronic ballasts is a 1-10V control voltage with control current being drawn ouf of the ballast (active load, no passive load). While analog control (0-10V) used in entertainment lighting ramps up darkness to brightness, that is from 0V (0 %) (idle state) to 10V (100 %), architectural lighting control ramps down from 100 % (10V, idle state) to 1 % (1V): from brightness to darkness. Do not try to measure the control voltage without ballast connected: this will not work, since the ballast feeds the control circuitry.
1 to 4 SLOTS
The decoder 3044B-H is a 4 channel decoder and can drive up 50 ballasts (assuming a control current of 0,5mA per ballast). Some manufacturers specify higher drive currents for their ballast. In this case, please adjust the number of ballasts connected to each output accordingly.
Since analog electronic ballasts cannot be switched off using the control interface, power must be removed to switch off the lamp at DMX level 0. That’s why the 3044B-H features 4 electronically switched mains outputs to supply power to the ballasts. This will work for single ballasts; when driving multiple ballasts per output use a power contactor to switch the supply line.
The decoder mounts on DIN rail 35 mm and is optimally suited for electric cabinets.
