Isolated Constant Power DALI-2 / D4i LED Driver U7+

DALI2 and D4i Isolated Constant Power LED Driver U7+ delivers precise, reliable power for modern LED luminaires. Applied to road lighting and urban illumination projects, its core functions are isolated constant-power output, NFC-programmable current setting, full DALI-2 and D4i protocol support (including Parts 150, 250–253) plus time-control dimming, and built-in 16 V bus plus 24 V auxiliary supply.  

Operating from 176–305 Vac with standby power under 0.5 W, the driver solves frequent outdoor lighting problems such as surge damage, thermal runaway, voltage fluctuations and complicated commissioning. Available through flexible OEM/ODM services, the U7+ series lets manufacturers customize branding, current ranges and interface details while retaining certified performance and rapid market readiness.
