Shenzhen, China – September 2026
ElisaCustom is pleased to announce the release of our new DMX512 Constant Voltage Decoder Series, available in 1‑channel, 3‑channel, 4‑channel, and 5‑channel configurations. Designed for professional lighting control systems, these decoders convert standard DMX512/1990 signals into PWM outputs for constant voltage LED lighting — ideal for architectural, stage, and commercial installations.
The Story Behind This Order: Simon’s Customisation Journey
This product may be a standard offering, but Simon approached it with the thoroughness of a true professional. Before placing his bulk order, he requested samples to verify compatibility with his existing system.
During the sample phase, we provided two connector options for evaluation: RJ45 and terminal block (screw‑type). After testing both, Simon confirmed that the RJ45 connector was the better fit for his installation requirements.
The result? A bulk order of 324 units, all configured with RJ45 connectors — demonstrating how even standard products can benefit from thoughtful, client‑driven customisation.
