Feature of OTTIMA DALI led driver


1) The dimming curve is perfect and smooth, without pause, OTTIMA DALI dimming range is 0.1% -100%; (However MW and Inventronics brand minimum 10%)


2) The DALI standard is exactly the same as that of the DALI Alliance. This requires testing with equipment that complies with the DALI Alliance. There are only a few of this equipment in China, and OTTIMA have such test equipment.

The standard of the DALI Alliance One point is to have output short-circuit feedback, but many manufacturers do not do this in order to save costs, however OTTIMA test equipment have such function.

3) The output of our DALI power supply is PWM output, which means that it can be load-free, and the general output PWM is only a few hundred HZ, but OTTIMA DALI led driver output PWM can reach 4000HZ or even 20000HZ (low output frequency, mobile phone Photo will flash, there are horizontal bars, after reaching 4000HZ, in accordance with international electrical standards, flicker can be waived)
