CCC4

The ENTTEC CCC4 is a 4-channel, installation-grade constant current (CC) LED dimmer with PLink or DMX input, designed for high-precision color rendering and high-power LED installations.

From the Manufacturer

The ENTTEC CCC4 is a 4-channel, auto-addressable constant current LED dimmer built for professional lighting applications. It supports a wide input voltage range of 12–48V DC, with output current preset at the factory to dim compatible constant current fixtures up to 1A per channel. By delivering a regulated current output per channel, the CCC4 ensures consistent brightness and reduces the risk of LED burnout or thermal runaway — especially beneficial for high-power installations. Its compact, solid-state, fanless design makes it virtually silent during operation, and built-in mounting points accommodate an optional TS35 DIN rail clip for installation in control cabinets or on surfaces and walls.

For optimal performance, the CCC4 integrates with ENTTEC's Pixelator series controllers via the long-range PLink protocol. Simply chain devices together using Cat 6 cable — extending up to 300m between each unit — and the CCC4s will auto-address themselves, eliminating the need for manual addressing. Alternatively, the CCC4 can receive data from any DMX controller, with RDM support for start address configuration and temperature monitoring. DIP switches allow users to select between RGB/RGBW mode and 8-bit/16-bit dimming resolution, while overtemperature protection automatically dims output to black if operating temperature becomes too high, restoring output once the device has cooled.
