Leistungsverstärker Phasenan- & abschnitt

Wie CLS-EXP-DIM, nur ausgelegt für Phasenanschnitt und Phasenabschnitt.

The CLS-EXP-DIMU enables the expansion of Crestron iLux™ Integrated Lighting System (CLS-C6 series) and other Crestron lighting dimmers to allow dimming of both forward and reverse phase type loads. Supported loads include LED¥, electronic low-voltage, magnetic low-voltage, incandescent, neon/cold cathode, or 2-wire dimmable fluorescent. A single model supports 120, 230, or 277 Volt loads up to 16 Amps.

The CLS-EXP-DIMU simplifies installation by auto-detecting the dimmable load type connected to it and selecting the appropriate operating mode to control that load. Reverse phase (trailing edge) mode supports incandescent and electronic low-voltage load types, while forward phase (leading edge) mode handles magnetic low-voltage, neon, and other inductive load types.

Any output channel of the iLux system can be used to control the CLS-EXP-DIMU to dim a fully loaded circuit. It is also compatible with CLW-Series* in-wall dimmers and select CLX-Series lighting control modules†. The metal enclosure is designed for mounting to a vertical surface‡, 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.

* CLW-Series device must have a dedicated neutral.

Compatible only with forward-phase dimming modules.

Must be oriented upright, mounted to a vertical surface, with 6 inches (15 cm) minimum spacing above and below for proper ventilation and heat dissipation.

§ Captive screw terminals accept up to two 22 to 12 AWG (0.34 to 4.0 mm2) wires per terminal.
