The EB 6/9K High Speed Electronic Ballast with ALF and DMX has been introduced by ARRI to power their ground-breaking M90 6K/9K lamp head. This versatile power source has been streamlined and packed with features like CCL to compensate for power loss over long cable runs and ALF (Active Line Filter) which 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 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 version of the 6/9K ballast allows high speed shooting of sports events, industrial applications, automotive component testing and ballistics or material testing without any concerns about flicker.
Since the M90 can accept either of Osram's 6K or 9K lamps, the EB 6/9 kW features automatic detection of both lamps and lamp heads. There's also a low noise mode and DMX on/off and 100-50% dimming control. To help you monitor the unit while shooting, it has LED indicators for input voltage, protective earth, over temperature, lamp on, detected lamp, and low noise mode as well as an illuminated on/off switch.
