The AB series ballast from Lightronics is designed to control high-efficiency lighting sources, such as dimmable compact fluorescent and LED light fixtures. It can be configured to control a three-wire hot-switched ballast or a four-wire 0-10VDC-type ballast. The AB is available in a three- or six-channel version, with a maximum load of 20A per channel. Control is via a DMX console or any of the Lightronics Unity architectural remote stations. Scene recall can also be accomplished using a momentary contact signal from a switch, motion sensor, or similar device.
