D4i Certification

uPowertek D4i LED drivers passed D4i certification, meet DALI 101, 102, 150, 207, 250, 251, 252, 253 standard. Especially for DALI part 150, 24V auxiliary power, which is an optional function, uPowerTek LED drivers have it.

Most of the projects require D4i certified LED drivers, only the certified LED drivers can meet the DALI standard and are compatible with different kinds of D4i controllers. There will be many issues if the driver is not D4i certified, such as reading power issues and dimming issues.

DALI Testing Lab

Upowertek has the professional DALI test equipment Probit to make sure that our DALI drivers comply with the DALI IEC62386 standard.

DALI Testing Sequence

Without the testing lab, it’s hard to make sure that the D4i LED driver meets every DALI command. Even a simple command can cause an incompatible issue with DALI controllers. So it’s better to choose D4i LED drivers from companies that have the DALI testing lab. uPowerTek LED drivers passed the DALI command test and make sure that your LED lamps have reliable power.
