CVC4

The ENTTEC CVC4 is a 4-channel, installation-grade constant voltage (CV) LED dimmer with PLink or DMX input, delivering ultra-smooth 8- or 16-bit dimming across four 5A channels for professional LED strip installations.

From the Manufacturer

Designed and made in Australia, the ENTTEC CVC4 is a state-of-the-art constant voltage LED dimmer controlling up to 20A across four 5A channels with ultra-smooth dimming at 16- or 8-bit resolution. Featuring PLink auto-addressing, simple DIP switch mode selection, and a rugged ABS body with aluminum heat sink, the CVC4 is built for fast, flexible LED strip installations. Its fanless design ensures quiet operation, while a user-serviceable fuse protects against short circuits and overtemperature protection automatically reduces output to prevent overheating.

For optimal performance, the CVC4 integrates directly with ENTTEC's Pixelator series controllers via PLink — no DMX conversion required. Simply chain CVC4 units together using Cat 6 cable up to 300m between devices and they will auto-address themselves, dramatically speeding up installation time. DMX512A input is also supported, with RDM available for start address configuration and temperature monitoring. The CVC4 is fully backward compatible with systems using ENTTEC's DIN-LED4PX and CVC3 (note: adjustments in dimming curve between models may be needed).

Features

• 4-channel constant voltage (CV) LED dimmer with up to 5A per channel (20A total)
