ARRI 575/1200W High Speed Electronic Ballast with ALF (1000 Hz, CSA Certified)

The ARRI 575/1200W High Speed Electronic Ballast with ALF is designed for use with ARRI 575W or 1200W HMI luminaries for high-speed photography at 500 to 5000 frames per second The ballast operates 1000 Hz rather than the typical 50 to 200 Hz and incorporates ALF (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. ALF also minimizes the current carried back on the neutral leg of the power infrastructure. This ballast has been certified for sale and use in Canada by the Canadian Standards Association.
