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

The CVC4, designed and made in Australia, is ENTTEC’s state-of-the-art constant voltage LED dimmer. It controls up to 20A across four 5A channels with ultra-smooth dimming at 16- or 8-bit resolution. Featuring auto-addressing, simple mode selection, and a rugged ABS body with surface-mount tabs or a DIN rail adaptor, the CVC4 is easy to install. Its fanless design ensures quiet operation, while a user-serviceable fuse protects against short circuits, and temperature detection limits LED output to prevent overheating. Ideal for fast, flexible LED strip installations.

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

If you’re using a DMX input, simply connect this to the CVC4’s input then link out of it using PLink.

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.

The CVC4 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.

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!

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.

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 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.

Given the CVC4’s range of operating modes and flexibility to accept DMX or PLink data, it is fully backward compatible with systems using ENTTEC’s DINLED-4PX and CVC3 (note: adjustments in dimming curve between different models may be needed).

ENTTEC are proud to back up the confidence in our research, engineering and quality control with a 3-year manufacture defect warranty on this product.

How do I wire my CVC4 up?

The diagrams here provide a general view of several of the CVC4’s core setup concepts. In particular, you’ll see how easily the CVC4 can be integrated directly with a PIXELATOR system without having to convert to DMX first, unlike the case with other off-the-shelf LED dimmers. So many possibilities! For more detailed information regarding project requirements of different scales and types, please consult the Installation Guide in the download section below.

Specifications

12-24V input (20A maximum)

Huge 1KHz PWM signal refresh rate

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.

Passive cooling with internal overheating protection.

Dim constant voltage (CV) LED strip (4 x 5A per channel maximum).

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).

Convert DMX to PLink on each device – changing the address of the first CVC4 in the chain will update the rest of them.

User-serviceable fuse to protect against short circuits.

Compact design with integrated M4 surface mounting holes or TS-35 DIN rail mount.
