ARRI Electronic Ballast EB 575-1200W with Active Line Filter

The Arri Electronic Ballast is for both 575W and 1200W lampheads is now equipped with an Active Line Filter. This technology of the ballast offers the same high quality standard as all ARRI ballasts and runs from 90 volts to 250 volts. The Active Line Filter contributes to more economical use of power.

The A.L.F. system performs power factor correction to eliminate the phase shift between the voltage and the current sine wave. With unity of Power Factor the required apparent power is optimized to a minimum. Since electricity supply companies charge for apparent power, A.L.F. helps to save costs.
