The MOVING iMAGE TECHNOLOGIES IS-30 is an AC power spike arrestor and filter-conditioner. It has been designed by MiT’s engineers specifically to protect digital projectors and other cinema electronics in the d-cinema age. It consists of spike and surge protection components combined with a rugged, industrial grade 3-phase EMI/RFI filter, in a unique circuit arrangement that protects and absorbs spikes and surges line-to-ground as well as line-to-line. The unit includes a counter display to indicate how many power spikes and surges have been absorbed. It also includes LEDs that indicate the status of all AC phases.
