ENTTEC CVC4 Constant Voltage Dimmer

4-Channel Constant Voltage LED Dimmer for DMX and PLink Control

The ENTTEC CVC4 Constant Voltage Dimmer is a compact 4-channel LED dimmer designed for professional constant voltage LED strip installations in architectural lighting, entertainment venues, stages, houses of worship, events, and integrated lighting systems. Engineered and manufactured in Australia, it provides precise dimming control for LED tape and other compatible constant voltage lighting projects.

The CVC4 delivers up to 20 amps across four 5 amp channels and supports 12 to 24 VDC input and output. It offers selectable 16-bit or 8-bit resolution, ultra-smooth dimming, DMX/RDM control, and onboard conversion from DMX to ENTTEC PLink, giving lighting professionals a flexible control path for both direct DMX operation and chained PLink-based installations.

For faster setup across larger LED dimming systems, the CVC4 supports auto-addressing through PLink, allowing devices to be chained with Cat6 cable up to 984 feet between units. A status LED and mode selection DIP switch allow users to toggle between bitrate and RGB/RGBW operating modes, while the fanless passive cooling design keeps operation virtually silent.

The CVC4 is built for practical installation with integrated M4 surface mounting holes and TS35 DIN rail mounting support. It also includes short-circuit protection, a user-serviceable safety fuse, and onboard temperature monitoring that reduces output to help prevent overheating.

System Integration

The ENTTEC CVC4 fits into larger lighting systems by converting DMX to ENTTEC PLink while also supporting DMX/RDM control and device monitoring. It can be installed using surface-mount tabs or TS35 DIN rail mounting, connected to compatible 12 to 24 VDC LED tape, and chained between devices using PLink over Cat6 cable for fast expansion across multi-zone constant voltage LED installations.

Broadcast Workflow Benefits

For professional lighting and production environments, the CVC4 helps simplify constant voltage LED control by combining four high-precision dimming channels, DMX/RDM communication, PLink auto-addressing, and silent fanless operation in one compact device. It reduces manual addressing time, supports smoother dimming performance, and helps keep LED tape systems organized in installed or portable workflows.
