Description

Crestron GL-EXP-DIMU-CN Green Light Universal Dimmer Expansion Module for Cresnet Communications

The GL-EXP-DIMU-CN is a single-channel universal dimmer expansion module that allows for added lighting zones without an additional cabinet install. The expansion module controls electronic and magnetic low-voltage, LED, incandescent, and 2- wire fluorescent loads. Utilizing proprietary zero-cross filter technology, the GL-EXP-DIMU-CN compensates for line voltage and frequency fluctuations to provide immunity to power line noise and a dramatic reduction in lamp flicker.

Auto-Detecting Universal Dimming: Under normal operation, the GL-EXP-DIMU-CN detects the connected load type and selects the appropriate operating mode automatically. Reverse phase (trailing edge) mode supports incandescent and electronic low-voltage load types, while forward phase (leading edge) mode handles magnetic low-voltage and other inductive load types. Center phase mode is also available, combining reverse and forward phase load control to address special cases. The operative mode is indicated by two LEDs located on the front panel.

Cresnet® Communications: The GL-EXP-DIMU-CN interfaces with a Crestron control system via Cresnet. Cresnet is a simple 4-wire network bus that provides the communications backbone for a system of Crestron lighting dimmers, switches, keypads, shades, thermostats, and other devices.

Emergency Lighting Control: The GL-EXP-DIMU-CN is UL® 924 listed for use in controlling an emergency lighting load. In the event of a power failure, a contact closure from a power loss sensor (GLS-PLS-120/277, sold separately) activates the override mode in the GL-EXPDIMU-CN to turn on the lighting load if it is off (assuming line power is supplied by a backup power source). The override dimming level can be preset to any value when commissioning the lighting system, so even if the load is already on prior to a power failure, it will change to the preset level when override mode is activated.

Plenum Rated NEMA Enclosure: The GL-EXP-DIMU-CN is designed to be mounted to a vertical surface and is UL 2043 compliant to allow 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.
