Leistungsverstärker Phasenanschnitt

Leistungsverstärker für iLux oder CLXI Dimmer. Dimmt Phasenanschnitt bis 3680 Watt. Geeignet zum Dimmen von Glühlampen, Hochvolthalogenlampen und Niedervolthalogenlampen mit magnetischen Trafos. Benötigt min. 25 Watt Grundlast. Die Ansteuerung erfolgt per Phasenanschnitt.

The CLS-EXP-DIM enables the expansion of Crestron iLux® Integrated Lighting System (CLS-C6 series) and other Crestron® lighting dimmers to support 120, 230, or 277 Volt loads up to 16 Amps. It allows any output channel of the iLux system to dim a fully loaded circuit of LED[1], incandescent, magnetic low-voltage, neon/cold cathode, or 2-wire dimmable fluorescent lighting loads. It is also compatible with CLW-Series[2] in-wall dimmers and select CLX-Series lighting control modules[3].

The CLS-EXP-DIM is designed for mounting to a vertical surface[4], and can be installed in an environmental air-handling space above a suspended ceiling. Conduit knockouts are provided on the bottom and lower sides. All connections are made via screw terminals behind the front cover.
