The Sunricher SR-2108AC-4CH-DIN is a professional 4-channel DMX512 phase-cut dimmer designed for controlling mains-powered lighting loads in entertainment and architectural environments. Built for DIN rail installation, it provides a reliable solution for integrating phase-dimmable LED, halogen, and incandescent lighting into DMX-based control systems.

With four independently controllable output channels, the unit offers flexible configuration from 1–4 DMX channels. Featuring RDM (Remote Device Management), addressing and configuration can be completed remotely from a compatible console, reducing commissioning time and simplifying system management.

Using trailing-edge (reverse phase) dimming, the SR-2108AC-4CH-DIN delivers smooth, flicker-free dimming performance optimised for modern LED loads. A built-in digital display allows for quick local setup, while adjustable dimming curves provide fine-tuning for demanding applications.
