LTECH SE-12-100-450-W2D 12W DALI-2 Tunable White LED Driver

100–450mA DALI-2 DT6/DT8 Constant Current Driver

The LTECH SE-12-100-450-W2D is a compact 12W constant-current LED driver designed specifically for tunable white lighting applications. With a selectable output current from 100mA to 450mA and an operating voltage range of 9–42V DC, it provides flexible compatibility with a wide range of constant-current LED modules.

Supporting DALI-2 DT6 and DT8 control, the driver provides smooth digital dimming from 0–100% down to 0.01%. Its two-channel warm white and cool white output enables precise colour temperature adjustment, while the constant-power design helps maintain consistent brightness as the colour temperature changes.

Output current can be selected using the integrated DIP switches, with settings of 100mA, 150mA, 200mA, 250mA, 300mA, 350mA, 400mA and 450mA. The two output channels share the available 12W power, providing a practical solution for tunable white luminaires while simplifying driver selection and installation.

Operating from a universal 100–240V AC input, the SE-12-100-450-W2D features flicker-free T-PWM™ dimming together with over-voltage, over-temperature, short-circuit and overload protection. Its compact Class II construction, SELV output and 5-year manufacturer warranty make it a dependable solution for professional tunable white LED lighting systems.
