8-channel 277V Universal Dimmer Module with Terminal Block, 2 Feeds

Provides eight channels of technologically advanced universal dimming for commercial lighting applications. Supports LED, incandescent, magnetic low-voltage, electronic low-voltage, and 2-wire dimmable fluorescent lighting loads. Installs in a CAEN wall mount automation enclosure as part of a complete Crestron® centralized lighting control system.

The Crestron® GL-CAEN-2DIMU8-277 is an eight-channel, two-feed universal dimmer module designed for 277V commercial lighting system applications. It installs in a CAEN enclosure and provides control of a wide range of dimmable lighting load types including electronic and magnetic low-voltage, LED, incandescent, and 2-wire fluorescent. It may also be used to switch non-dimmable lighting loads. Dual feed capability provides two independent four-channel dimmers in one module space. Each output channel is rated for 692 Watts (2.5 Amps), with a total module rating of 5540 Watts (20 Amps) when fed from two separate 15 or 20 Amp feeds.

Auto-Detecting Universal Dimming

Under normal operation, the GL-CAEN-2DIMU8-277 detects the connected load type on each channel and selects the appropriate operating mode for each channel automatically. 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. The operating mode may also be selected manually via software or programmatically via the control system.

Ultra-Reliable Performance

The GL-CAEN-2DIMU8-277 is a technologically advanced universal dimmer that delivers unparalleled reliability and optimal dimming performance, even in noisy electrical environments. Patented “Constant Power” technology dramatically reduces lamp flicker and maximizes stability under noisy power conditions. This cutting-edge technology quickly adjusts the dimmer’s on-time response to changes in input voltage so that power is constantly and consistently delivered to the load. Voltage sag and peak overshoot no longer cause changes in load output, ensuring reliable lighting performance and a comfortable working environment.
