GL-EXP-DIMFDB-CN Crestron Green Light® 3-Wire Fluorescent Dimmer Expansion Module, Cresnet® The Crestron Green Light® GL-EXP Series delivers a family of professional lighting control modules for Cresnet® or DALI® based lighting systems. Designed for easy installation on a wall or above a suspended ceiling, these modules offer a perfect solution for adding extra lighting zones to any system without requiring an additional lighting cabinet. The GL-EXP-DIMFDB-CN is a single-channel dimmer expansion module designed to control 3-wire electronic fluorescent dimming ballasts. Utilizing proprietary zero-cross filter technology, the GL-EXP-DIMFDB-CN compensates for line voltage and frequency fluctuations, providing superior immunity to power line noise and a dramatic reduction in lamp flicker. This module interfaces with a Crestron® control system via Cresnet,[1] a simple 4-wire network bus that acts as the communications backbone for Crestron lighting dimmers, keypads, shades, thermostats, and other devices. In the event that Cresnet communications should be disrupted for any reason, the GL-EXP-DIMFDB-CN includes an override feature, which allows a single dimming preset to be saved at setup and activated at any time via an external contact closure. The GL-EXP-DIMFDB-CN is designed to be mounted to a vertical surface[2] and complies with UL 2043 standards for installation in an environmental air-handling space above a suspended ceiling. Conduit knockouts are provided on the bottom and lower sides of the unit. All connections are made via screw terminals behind the front cover.
