In addition to its well known electronic ballasts, ARRI has developed several DC ballasts: 125/200W, 200/400W and 575/1200W. The two smaller units can be combined with battery belts for use as portable daylight systems. The bigger 575/1200W DC ballast is often used where no AC public net is available.
Features:
   No additional adaptation required
   Detection of the connected luminary through lamp connector
   Protection against:
       under/over-voltage on DC input        DC polarity reversal        overheating
   Power switches off automatically after 3 seconds when lamp doesn't strike
   Detailed service documentation with test procedures
   Good service assistance
