This Arri 6/12kW Electronic Ballast with ALF and DMX is a 220 VAC electronic ballast with an Active Line Filter. ALF provides a higher Power Factor resulting in more efficient power use. This is accomplished by shifting the voltage and current waveforms in phase and minimizing harmonics and spikes. The ALF also minimizes the current carried back on the neutral leg of the power systems.
Includes built-in protocol for DMX dimmer board control.
Auto Line Filter prevents color shift when the fixture is dimmed.
