3. Product Description
The ARRI EB MAX 1.8 is part of an optimized lighting system along with all
ARRI lampheads specified for operation with the EB (see fig.1a to 1d, page 23).
It is suitable for both professional indoor and outdoor use (IP 21 protection).
In conjunction with suitable 1800 W lampheads 1800 W lamps as well as 1200
W lamps can be used. The inserted lamp is detected automatically and the
output power is regulated accordingly. In all other lampheads only lamps of
fitting power must be used.
Furthermore, a suitable lamphead enables the ballast to compensate the
electrical losses on the head to ballast cables. The output power of the EB will
be increased so that the lamp is operated at its rated power.
Note: The Electronic Ballast EB MAX 1.8 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.
The ballast meets the requirements of European Standard EN 61000-3-2.
Compared to magnetic ballasts there are a number of advantages when
operating daylight-lamps with ARRI Electronic Ballasts:
Flicker free light
No synchronization of cameras necessary
Typical light ripple max. 3 %
Light intensity increased by at least 5 %
Constant lamp power
Constant color temperature
Constant light quality
Control of electric power of the lamp between 50...100%
Variation in power supply voltage of 10% has no influence on the power of
the lamp (see also "Technical Data" for limits, on page 21).
Variation in power supply frequency of 10% has no influence on the power of
the lamp
Operating life time of the lamp increased by at least 20%
Substantially less volume and weight compared to magnetic ballasts
The ballast is built-in to a casing with type of protection IP 21.
CCL (Compensation of Cable Losses)
The CCL function compensates the electrical losses on head to ballast
cables by automatically increasing the output power (only in conjunction with
suitable 1800 W lampheads).
