Product Description

Robust and reliable, ENTTEC’s CVC4 is the ultimate high fidelity, constant voltage (CV) LED dimmer.

The CVC4 is the next evolution of the ENTTEC LED dimmer, building upon the the CVC3 and DIN-LED4PX. Think of the CVC4 as a higher power version of these popular models, with the added option for 16-bit dimming, plus the ability to configure it to take up the same channel footprint as a CVC3 in an existing application if you wish.

Capable of controlling up to 5A on each of its four channels at either a 16- or 8-bit resolution, the CVC4’s ultra smooth-dimming, auto-addressing functionality and simple mode selection make it one of the most comprehensive yet versatile devices imaginable.

With rugged, in-built surface mount tabs, it’s easy to install, whilst its solid-state, fanless design means that the CVC4 is virtually silent when in operation. Incorporating a user-serviceable fuse to reduce the amount of external components and wiring required for a safe installation, the CVC4 has been engineered to bring the ultimate in installer-friendly flexibility and fast deployment when constructing a constant voltage LED strip project.

  • 12-24V input (20A maximum).
  • Output to LED strip (5A per channel maximum).
  • Huge 1KHz PWM signal refresh rate.
  • PLink in and out connector for auto-addressing (each unit can be spaced up to 300m away from the next when using PLink over Cat6 cable).
  • Single DMX connector for DMX/RDM input, or chaining between devices.
  • Status LED and mode selection DIP switch to toggle between bitrate and RGB/RGBW operating modes.
  • User-serviceable fuse to protect against short circuits.
  • Passive cooling with internal overheating protection.
  • Compact design with integrated 4mm surface mounting holes.



The ENTTEC CVC4 LED dimmer: Let's get stuck in!

It's time to join everyone's fave Aussie electrical engineer, Jordan, as he gets well and truly stuck into the all new ENTTEC CVC4 LED dimmer.




This priceless function speeds up installation time and works intuitively for installers, even if completely unfamiliar with DMX. Simply connect your CVC4s using PLink protocol, add power, and the CVC4s will all auto-address themselves. More advanced users can also address and monitor each CVC4 using RDM.


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!

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, the CVC4 integrates a user-serviceable 20A ATO blade fuse that can be sourced easily and inexpensively to protect against dead shorts. If your installation draws less than 20A you can downrate the fuse to an appropriate level to suit your installation. To learn how to replace the CVC4’s fuse, check out our short instructional video in the download section below.

Overheating protection

Overheating protection

If the CVC4 ever reaches a high operating temperature, it will automatically reduce its output by 50% to prevent overheating and blink the LED Indicator red to notify the user until the device has sufficiently cooled.

Backward compatible with the CVC3 + DIN-LED4PX

Given the CVC4’s range of operating modes and flexibility to accept DMX or PLink data, it is fully backward compatible with the DINLED-4PX and CVC3.

Designed for longevity

MOSFETs are used to dim the LEDs wired to the CVC4’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 the metal casing in order to transfer heat outside the unit to better regulate its performance. Be wary of many cheap OEM products that do not allow these components to dissipate heat correctly, severely risking the safety and reliability of your project.
