The Easeic LND127AL is a constant current LED DALI dimmable driver built for luminaires that need smooth dimming and a compact fit. It delivers up to 27W and offers an adjustable output current from 200mA to 1050mA, selected on site through the built-in DIP switch.

Key features of this DALI dimmable LED driver

• Output power, up to 27W
• Adjustable current, 200mA to 1050mA via DIP switch
• Output voltage, 3V to 66V DC, max open circuit voltage under 75V
• Dimming protocols, DALI 2 with DALI feedback, 1-10V, PWM and PUSH-Dim
• Dimming range, 0% to 100%, with LED start possible from 0.1% brightness
• Input, 100 to 277V AC, 50/60Hz

Dimming and control

Alongside DALI 2 support, the driver responds to 1-10V, PWM and PUSH-Dim signals, so it fits into most existing control set-ups without a protocol change. The analogue flicker-free dimming keeps the light stable right down to 0.1% output, which suits offices, retail units, hospitality fit-outs and architectural lighting where a visible flicker or step in the dimming curve would stand out.

Efficiency and protection

Efficiency reaches up to 88%, power factor stays above 0.95 and total harmonic distortion is kept below 10%. Built-in protection covers short circuit, over current, over voltage and open circuit conditions, giving the driver a level of resilience suited to long-term installation inside a luminaire rather than an exposed enclosure.

Compact, slim housing

At 280 x 30 x 26mm the LND127AL is slim enough for compact and architectural fittings. Push-in terminals cut down wiring time on installation, and the universal 100-277V AC input means the same driver can go into international projects as well as UK retrofits.
