Users see that the input voltage range marked on the power supply 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 power supply driver within the voltage range defined in the specification; the voltage range marked on the power supply is to meet safety regulations and ensure the correct use of the power supply.

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

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

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

The LED driver power supply glue can be thermally conductive and waterproof, guide the heat of the components and dissipate it, even out the internal temperature, reduce the penetration of water molecules, and improve outdoor adaptability.
