The main difference is that 0~10V can use a dimmer to turn off the LED driver output, while 1~10V can only achieve a minimum of 10% dimming.

There will be a short-term high current when the LED driver is powered on, which will return to normal after the LED driver is turned on. This phenomenon is normal and will not damage the LED driver.

The single-stage LED driver integrates the front-stage power factor correction and the rear-stage converter. It has low cost but is easily affected by the input LED driver and is suitable for stable voltage occasions. The two-stage separate design has a complex structure but can adapt to harsh environments.

Users see that the input voltage range marked on the LED driver is 85-265VAC, and the actual input voltage is 100-240VAC. During safety certification, a stricter ±10% test will be performed (IEC60950 stricter +6% -10%), so there will be no problem in using the LED driver within the voltage range defined in the specification; the voltage range marked on the LED driver is to meet safety regulations and ensure the correct use of the LED driver.

PFC (Power Factor Correction) is mainly used to improve the ratio of effective power to apparent power at the input end of the LED driver. Generally, the power factor of the input end of a model without a PFC circuit is only 0.4~0.6, while that of a model with an active PFC circuit can reach more than 0.95.
