ARRI EB 2.5/4 – the classic electronic ballast that operates at standard current frequency of 50 Hz or 60 Hz. Should be used with lamps of 2500W and 4000W.
The EB MAX 2.5/4 is designed for two power classes: 2,500 W and 4,000 W. When combined with state-of-the-art ARRI daylight lamp heads such as the True Blue D25 and D40 or M-Series M40, it enables optimal performance and advanced control for high image quality − at any frame rate.
The EB MAX 2.5/4 is equipped with essential features such as Active Line Filter (ALF) and Compensation of Cable Losses (CCL), delivering
maximum light quality with efficient supply and wiring. The AutoScan feature ensures optimum light and image quality with a minimum of effort for high-speed recordings up to 1,000 fps and beyond.
Besides lamp operation at 50 or 60 Hz, if noise needs to be minimized, or at 75 Hz for standard frame rates, the EB MAX range accommodates high-speed frequencies at 1,000 Hz and − for the first time − at 300 Hz.
Three different modes are available for high-speed operation: AutoScan (fully automatic), Man (manual frequency control), or AutoMan (combining manual frequency setting with automatic frequency control). Using the AutoScan mode requires no further interaction by an operator. After a two-stage scan the lamp frequency is selected and set by the ballast; all parameters are continuously monitored and adjusted automatically, if required.
