LTECH D12 DMX/RDM High-Power Decoder

OLED-Display 12-Channel DMX512 Decoder for High-Power LED Loads

The LTECH D12 is a high-power, 12-channel DMX512/RDM decoder designed for demanding multi-channel lighting applications, delivering up to 5A per channel and a maximum output power of 1440W. Its human-machine interface combines an OLED screen with touch buttons, giving installers a simple, direct way to view status and adjust settings at the unit itself.

Powered from a 12-24Vdc supply, the D12 offers three DMX connection options — 3-pin XLR, RJ45 and green terminal, each with photoelectric isolation to improve signal transmission and interference resistance, with the green terminal also providing signal amplification. It supports three selectable control modes — DIM, CT and RGB — and its maximum load current and total power can be tuned across ten selectable PWM frequencies from 300Hz up to 18kHz, giving installers flexibility to balance output and flicker performance for different LED loads.

The decoder 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. It also includes short circuit, over-current and over-heat protection with 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, removing the need for high-altitude manual adjustment.

Combining high channel density, flexible PWM and dimming curve configuration, and comprehensive RDM-based management, the D12 is well suited to large-scale architectural, stage and commercial lighting installations that require a compact, high-capacity decoder for DIM, CT and RGB LED loads.
