Compact and virtually silent thanks to its fanless design, the CCC4 Constant Current Dimmer from ENTTEC is a 4-channel, auto-addressable, reliable constant current LED dimmer for lighting applications. It supports 12-48 VDC, with a preset output current that dims compatible constant current fixtures up to 1A per channel, ensuring consistent brightness. Another benefit is blade fuse and DIP switches for selecting RGB/RGBW mode and 8-bit/16-bit resolution. 16-bit enable finer control over your installations.
