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) Supports 12–24V DC input voltage for compatibility with common LED strip installations PLink auto-addressing — chain CVC4 units via Cat 6 cable up to 300m between devices with no manual addressing required DMX512A input with RDM support for start address configuration, temperature monitoring, and firmware updates Integrates directly with ENTTEC Pixelator series controllers via PLink without DMX conversion DIP switch selection for RGB or RGBW mode and 8-bit or 16-bit dimming resolution Overtemperature protection — output automatically reduces by 50% and LED indicator blinks red until the device has cooled User-serviceable ATO 20A blade fuse for protection against dead shorts; downrateable to suit installation draw MOSFET outputs bonded directly to an aluminum heat spreader for sustained safe operating temperature Compact, fanless design for silent operation DIN-rail mountable via optional TS35 DIN rail clip (included in box) Surface mountable via built-in mounting tabs Reverse polarity protection on power input connector Fully backward compatible with ENTTEC DIN-LED4PX and CVC3 1 kHz fixed PWM frequency 3-year manufacturer warranty Recommended use: Architectural LED strip installations, permanent installs, theatrical and studio LED dimming, high-power constant voltage LED fixtures Specifications Electrical Input Voltage: 12–24V DC Max.
