Product Description
Enttec 73926 CVC4 4-Channel Installation-Grade Constant Voltage LED Dimmer
Designed and made in Australia, the CVC4 is the next evolution of the ENTTEC constant voltage LED dimmer, building upon the CVC3 and DIN-LED4PX.
Capable of controlling up to 20A across its four 5A 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 LED dimmers imaginable.
With its rugged, black ABS body featuring in-built surface-mount tabs, or an attachable TS35 DIN rail adaptor, it’s fast, easy and versatile to install. The CVC4’s solid-state, fanless design also means it’s virtually silent when in operation.
A user-serviceable blade fuse to protects against short circuits., whilst it also has the ability to detect temperature and limit the LED output to reduce overheating.
The CVC4 has been engineered to bring the ultimate in installer-friendly flexibility and fast deployment when constructing a constant voltage LED strip project.
NOTE: YOU MUST PURCHASE AN EXTERNAL POWER SUPPLY, SEPARATELY, TO POWER THE ENTECC 73926: The CVC4 is powered by an external power supply that would be purchased separately. Typically speaking we recommend Meanwell power supplies LPVL-150-12 and Meanwell power supplies LPV-100-12.
Features
- 12-24V input (20A maximum).
- Dim constant voltage (CV) LED strip (4 x 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.
- Convert DMX to PLink on each device – changing the address of the first CVC4 in the chain will update the rest of them.
- 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 M4 surface mounting holes or TS-35 DIN rail mount.
Special Features
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 CVC4s using the PLink protocol, add power, and the CVC4s 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.
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!
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.
Overtemperature 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.
DIN rail mounting solution
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.
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 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.
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 systems using ENTTEC’s DINLED-4PX and CVC3 (note: adjustments in dimming curve between different models may be needed).
3-year warranty
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 much CV strip can the CVC4 control?
There are many variables to take into consideration when calculating such a figure, not least the precise specifications of LED strip you are connecting to it. ENTTEC offers a comprehensive range of RGB, RGBW, white, and color temperature adjustable (CTA) constant voltage (CV) strips to cover a large variety of potential requirements.
Our engineers have tested all currently available ENTTEC models and established that a single CVC4 unit will comfortably control anywhere from 17m of high output RGBW Strip (ENTTEC 9VLW) up to 29.5m of White LED Strip (ENTTEC 9CH) – calculated to allow for a 10% voltage drop & cabling overhead.
