RGBW DMX512 RDM Dimmer Decoder

This 4-channel constant voltage DMX512/RDM decoder delivers precise control for single-colour, dual-colour, RGB, and RGBW LED strip installations. Rated for DC12V–48V input and up to 20.5A total output current, it fits seamlessly into professional architectural, stage, and commercial lighting setups. Its black plastic enclosure provides mechanical protection while allowing efficient heat dissipation during sustained operation. The decoder implements full DMX512-A compliance and RDM functionality, supporting remote device identification, parameter readback, and address reconfiguration from any RDM-enabled console. Configuration is performed locally using the built-in digital display and intuitive button interface — no PC, app, or additional hardware needed. Three operational modes are supported: DMX-controlled (with RDM feedback), standalone RGB/RGBW program mode, and standalone 4-channel dimmer mode. Safety features include real-time temperature monitoring, overcurrent detection, and short-circuit auto-recovery — ensuring long-term reliability even under variable load conditions. Supplied as a single decoder unit; no batteries included or required.
