LTECH LU-75-500-1750-U1D2 75W DALI-2 Constant Current LED Driver

500–1750mA Programmable Driver with DALI-2 and Push DIM Control

The LTECH LU-75-500-1750-U1D2 is a 75W programmable constant-current LED driver designed for professional indoor lighting applications. With an adjustable output current from 500mA to 1750mA and a 10–54V DC output range, it provides flexible compatibility with a wide variety of constant-current LED modules.

Supporting DALI-2 and Push DIM control, the driver provides smooth dimming from 0–100% down to 0.1%. LTECH T-PWM™ dimming technology delivers flicker-free performance, while soft-on and fade-in functions help provide comfortable and precise brightness adjustment.

The output current can be programmed using the LTECH LT-ISET programmer, allowing the driver to be configured to suit different LED loads without requiring mains power during programming. The adjustable current range helps simplify driver selection and provides additional flexibility for luminaire manufacturers and professional lighting installations.

Operating from a wide 100–240/277V AC input, the LU-75-500-1750-U1D2 offers up to 89% efficiency and includes overheat, over-voltage, overload and short-circuit protection with automatic recovery. Its slim linear construction, 50,000-hour rated lifetime and 5-year manufacturer warranty make it a dependable solution for professional constant-current LED lighting systems.
