LTECH D3 DMX/RDM High-Power Decoder

OLED-Display 3-Channel DMX/RDM Decoder for High-Power LED Loads

The LTECH D3 is a high-power, 3-channel DMX512/RDM decoder designed for demanding multi-channel lighting applications, delivering up to 10A per channel and a maximum output power of 1440W. Its human-machine interface combines an OLED screen with three onboard buttons, giving installers a clear, menu-driven way to view and adjust settings directly at the unit without needing a separate configuration tool.

Powered from a 12-48Vdc supply, the D3 offers three DMX connection options — 3-pin XLR, RJ45 and green terminal, with the green terminal also providing signal amplification — for flexible, interference-resistant integration into a DMX network. Its DMX channel count can be configured as CH01, CH02 or CH03, allowing independent per-channel addressing or a single address to control multiple channels together, and PWM frequency can be set across ten selectable values from 300Hz up to 18000Hz to suit different LED loads.

Through its OLED menu, the D3 supports 8-bit (256 level) or 16-bit (65536 level) grey scale output, and standard, linear, log or fully custom 0.1-9.9 dimming curves, giving precise control over brightness response. The decoder also includes 10 built-in personalized lighting effects accessible in DMX master mode, short circuit, over-current and over-heat protection with automatic recovery and fault warning, power-on state management with fast self-test, and firmware upgrade support. Parameters, DMX addressing and device recognition can all be configured remotely via an RDM master console or mobile app, removing the need for high-altitude manual adjustment.

Combining high per-channel current capacity, an intuitive OLED interface and comprehensive RDM/app-based configuration, the D3 is well suited to large-scale architectural, stage and commercial lighting installations that demand robust, precisely controllable high-power channels.
