How to connect the negative control dimming module

Follow the steps below to install the module: 1 Press the dimming module onto the DIN rail until it clicks into place. 0-10V dimming is an analog low-voltage control method where a 0–10V DC signal adjusts LED driver output from 0% (off or minimum) to 100% (full brightness). It requires two extra low-voltage wires (violet/gray, 18 AWG Class 1) between the dimmer and each LED driver. Wire runs up to 150 ft with. ly require minimal maintenance. A complete 0-10V dimming control system includes a control interface, one or more light fixtures that support 0-10V dimming and a dedicated control wire pair that connects the 0-10V dimmer ntroller to the light fixtures. In asports stadium, a subtle flicker that the human eye misses can ruin a high-definition slow-motion replay during a critical game. At 10 Volts, the light operates at 100% intensity.
