The 120-220 VAC Arri 400/575W Electronic Ballast with ALF and DMX is a dual voltage electronic ballast for the Pocket Par 400 HMI light, and features remote DMX dimming control as well as an Active Line Filter for Power Factor Correction. 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. ALF also minimizes the current carried back on the neutral leg of the power systems.

This ballast has been certified for sale and use in Canada by the Canadian Standards Association.
