The HDL MDL64-KT53 is a sophisticated DALI-2 dimming controller designed to integrate seamlessly into a KNX ecosystem. This DIN-rail mounted gateway serves as the master interface, allowing a KNX system to command, manage, and monitor up to 64 DALI drivers (ballasts) with precision and reliability. By bridging these two powerful protocols, the KT53 enables advanced lighting strategies—from simple switching and dimming to complex Human Centric Lighting (HCL) and colour management—all within a single unified control environment.
