Dim 12 mains-powered lamps from one DMX line. This 12-channel DMX512 digital dimmer uses triac/SCR phase-cut technology to smoothly control incandescent, halogen, and properly labeled dimmable LED lamps. Small boards often run AC110-220V at 5A/ch; pro silicon boxes run AC220V single-phase or AC380V three-phase at 3kW/4kW per channel. DMX value maps to 0–100% brightness with linear/S-curve/square dimming curves, lamp preheat, soft-start, and signal-loss hold. CE-certified versions add opto-isolated DMX, MCB/fuse protection, RFI choke, and LCD addressing. Perfect for theaters, churches, KTV, bars, wedding halls, and façade warm-light dimming. Do NOT connect RGB/COB/pixel LED strips—those need PWM or SPI controllers, not a SCR dimmer.
12 Independent Triac Channels – Occupy 12 DMX addresses; console faders become lamp brightness.
Mains Dimming, Not Switching – 0–100% phase-cut dimming; smoother than relay ON/OFF.
Incandescent / Halogen / Dimmable LED – Resistive loads safest; dimmable-LED only if driver supports phase-cut.
Protections Built-In – Preheat, soft start, over-current MCB/fuse, over-temp, zero-cross detection, RFI choke; CE versions add opto-isolation.
Venue Grade – DMX IN/THRU, LCD/DIP address, linear/S/square curves, scene hold; single-phase 220V or 3-phase 380V models.
