Our common working voltage range, what are the main nominal?
Answer:Because the safety testing agency will tighten ±10% to test according to the given working voltage range. So actually the four ranges are 90-305Vac, 108-305Vac, 90-264Vac, 180-305Vac, 249-528Vac, Our company will conduct verification tests on the led driver reliability test according to the above range to ensure normal operation in this working voltage range.
