Lighting control dimmer module provides 2 independent channels of dimming for 230V incandescent, magnetic low-voltage, neon/cold cathode and dimmable 2-wire fluorescent loads. Each channel is rated for 2300W, with total module rating of 4600W when fed from two separate 16A feeds. Air-gap relays are provided on each channel output allowing an individual circuit to be serviced without disabling entire module. CLXI-series dimmers are rigorously built using 40A triacs and oversized heat sinks for ultimate reliability. Split-bobbin transformers and ground referenced electronics deliver superior performance. Lamp flicker is minimized through Crestron's innovative zero-crossing detection technique backed by proprietary firmware. Low-maintenance convection cooling assures quiet and trouble-free operation.
