ARRI High Speed EB 2.5 / 4

ARRI High Speed EB 2.5/4 – high speed ballast that generates not only standard current frequency of 50/60 Hz, but also greatly raised 1000 Hz. A new generation of 1000 Hz High Speed Ballasts that accept the challenge of modern digital high-speed photography with ease.

With the new 1000 Hz High Speed Ballasts it is easy to achieve high quality flicker free images even at frame rates of 1000 fps and in many cases beyond even with a single HMI daylight source. This new technology supplies the lamp with a greatly raised 1000 Hz square wave current, allowing worriless shootings for commercials, sports, industrial applications, automotive component testing, ballistics or material testing.

Should be used with lamps of 2500W and 4000W.

Ballast operates in three modes:

• 75 Hz or 1000 Hz (adjustable 900 - 1200 Hz) in «Flicker Free» mode

• 50 Hz in «Low Noise» mode 

Ballast weight – 20.5 kg. Made in a classic for the ARRI color - blue.
