ARRI: 2.5/ 4 High Speed Ballast (No DMX)

This ARRI electronic ballast powers 2.5K and 4K HMI heads and runs in high-speed mode for flicker-free operation at high frame rates. This version has no DMX input, so output is set at the ballast itself. It is the power unit that turns an ARRI 2.5/4 HMI into a working daylight-balanced key or fill.
