3. Product Description The Electronic Ballast ARRI EB 575 Event Six is part of an optimized lighting system
along with up to six luminaires specified for operation with the EB (see fig.1, page 15)
It is suitable for professional indoor use (IP20 protection).
Note: The Electronic Ballast EB 575 Event Six meets the European Council Directive
89/336/EEC of electromagnetic compatibility. Over an extensive range limits of radio
disturbance characteristic B are fulfilled. But on principle it has to be classified under
characteristic A, group 1.
Although limits of radio disturbance characteristic A are prescribed for industrial areas
administrative authority can allow the use of equipment with characteristic A in other
than industrial areas (DIN EN 55011).
Compared to magnetic ballasts there are a number of advantages when operating
daylight-lamps with ARRI Electronic Ballasts:
l Flicker free light
l No synchronization of cameras necessary
l Typical lightripple max. 3 %
l Light intensity increased by at least 5 %
l Constant lamp power
l Constant color temperature
l Constant light quality
l Control of electric power of the lamp between 50...105%
l Variation in power supply voltage of 10% has no influence on the power of the lamp
(see also "Technical Data" for limits, on page 13).
l Variation in power supply frequency of 10% has no influence on the power of the
lamp
l Operating lifetime of the lamp increased by at least 20%
l Substantially less volume and weight compared to magnetic ballasts
