Product Description

ENTTEC’s CVC4 is a high precision 4 channel, constant voltage (CV) LED dimmer, capable of dimming up to 5A of LED tape per channel at 12-24v.

The CVC4’s key feature is it’s integration of ENTTEC’s Pixelator family controller’s auto-addressing Plink protocol. This is a time saving system designed to allow users to simply chain one device to the next using Cat6 cable up to 300m away, removing the need to manually address each CVC4.

Alternatively use RDM to configure the start address of each CVC4 (default channel 001) and control over DMX. Another feature for the CVC4 is its ability to convert DMX to PLink protocol, connect a Cat6 cable to a CVC4 receiving DMX and the PLink protocol will auto-address all consecutive CVC4 along the daisy chain.

The CVC4 incorporates a user-serviceable blade fuse to protect against short circuits and features the ability to limit the output to reduce overheating.

With two DIP switches located on the CVC4, easily switch between RGB/RGBW and 8-bit/16-bit modes1.

The solid-state, fan-less design means the CVC4 is virtually silent when in operation.
