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.
Makes it simple to achieve high quality flicker-free images even at frame rates of 500-1,000 fps and in many cases beyond
Reduced size - comparable to EB 6000 Baby
Can also be used for 6K lamp heads
Automatic detection of 6,000W and 9,000W lamps in 9K lamp heads
CCL (Compensation of Cable Loss) maintains full power over long cable lengths
Power saving ALF (Active Line Filter)
DMX 512 for on/off and dimming
