CEHCO has built 7 DC lighting power supplies for movie studios since 1945. These units range from 200 KW to 625 KW. We have accumulated a wealth of expertise in developing these units for our customers. The systems are used to provide 60 Hz flicker free 120 VDC lighting for stages during movie production. Mobile units are installed with four wheels.
Power input to the units range from 480 VAC 3 PH to 4160 VAC 3 PH. Some of these units were located in close proximity to computers and other sensitive equipment. Thus the lighting systems were built with suppressors to inhibit EMI noise.
