ENTTEC’s CCC4 is the ultimate constant current (CC) dimmer for high power LED fixtures
ENTTEC’s CCC4 is a 4-channel, auto-addressable constant current (CC) LED dimmer designed for professional lighting applications. It supports a wide input voltage range of 12–48V DC, with the 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 lights. Its compact, easy-to-hide, solid-state, fan-less design means it’s virtually silent during operation. Additional safety features include a user-serviceable blade fuse and DIP switches for selecting RGB/RGBW mode and 8-bit/16-bit resolution.

Integrate
For optimal performance, integrate the CCC4 with an ENTTEC PIXELATOR series controller and utilise the long-range, auto-addressing PLink protocol. This time-saving solution allows users to simply chain devices together using Cat 6 cable, extending up to 300m and eliminating the need for manually addressing each CCC4.
Or, receive data from DMX controllers, using RDM to set the start address of each CCC4 (default channel 001). For enhanced configuration flexibility, the CCC4 can convert DMX to the PLlink protocol, streamlining the addressing for consecutive CCC4 units in the daisy chain.
Auto-addressing
This priceless function speeds up installation time as well as working intuitively for installers, even if completely unfamiliar with DMX. Simply connect your CCC4s using the PLink protocol, add power, and the CCC4 LED dimmer will all auto-address themselves. More advanced users can also address and monitor each CCC4 using RDM.
If you’re using a DMX input, simply connect this to the CCC4’s input then link out of it using PLink.
Safety fuse
Installing fuses to ensure that a system is safe takes up a great deal of time on site and can add to the space required per dimmer. To combat this, this clever LED dimmer integrates a user-serviceable 5A ATO blade fuse that can be sourced easily and inexpensively to protect against dead shorts. If your installation draws less than 5A you can downrate the fuse to an appropriate level to suit your installation.

DIN-rail mountable
The CCC4 features built-in mounting points to attach an optional TS35 DIN rail clip (included in the box) to allow you to install it in control cabinets or on surfaces/walls with a DIN rail fitted.
Configurability
16-bit dimming is increasing in popularity and allows for users to have much finer control over their installation. The mode selection DIP switches allow users to choose between either 16 or 8-bit resolution. Simply pick your desired bitrate, select from either RGB or RGBW LED strip, then you’re all set!
Overtemperature protection
If the CCC4 reaches a high operating temperature, output intensity will dim to black over 3 seconds and automatically dim back to the received value once the device has cooled.
Designed for longevity
MOSFETs are used to dim the LEDs wired to the CCC4’s output. During operation, it’s normal for these components to heat up.
So that this device can run safely at a sustained temperature, our engineers have ensured that all MOSFETs are directly bonded to a heat spreader to transfer heat to a larger area to dissipate better regulate its performance. Be wary of many cheap products that do not allow these components to dissipate heat, severely risking lifetime of your project.
3-year warranty
