The Horseman 24V AC Adapter for the Intelligent Shutter System (ISS) G3 gives you the freedom to work either in the studio or on location. The CPU can be powered from a standard rechargeable battery pack such as used in video camcorders or via the supplied AC adapter (100-240VAC) which doubles as a battery charger. A car battery adapter is also supplied and extra battery packs are available from any video supply store.

It should be noted that the control unit and the shutter itself receive their power from the CPU and need no power supply of their own.
