Ltech LT-401-15A DALI2 CV Controller, 12-48V, 15A, with NFC Setting

The LT-401-15A is a high-performance single-channel constant voltage DALI LED driver, engineered for professional indoor lighting applications. Supporting the DALI bus standard (IEC62386-101, 102, 207), it delivers up to 15A output current with a maximum load of 720W. The driver offers 0–100% dimming down to 0.1% via PWM digital dimming without affecting LED colour rendering. Through the NFC Lighting App or NFC programmer, users can easily configure DALI address, dimming curve, PWM frequency, and other advanced parameters. Housed in a fully protected, durable plastic enclosure, it ensures safe and reliable operation with multiple protection features.
