The difference between a wide input 100-277vac led power supply and an 180-265vac led power supply is: the voltage output range is different, the adaptability to the power source is different, and the lack of power is different.

The voltage output range is different
1. Wide power supply: The wide power supply voltage output range is generally in the standard of 85～265VAC.

2. Ordinary power supply: The voltage output range of ordinary power supply is generally in the standard of 12vdc 24vdc led driver 180V-240V.

Different adaptability to power supply

1.100-277vac power supply: The wide-width power supply has relatively strong adaptability to the power supply UL listed and is suitable for places where the power supply voltage is unstable.

2.Ordinary power supply: Ordinary power supply has relatively weak adaptability to the power supply and is suitable for places where the power supply voltage is stable.

Three, the shortcomings are different

1. Wide power supply: When the electrical appliance is running, the wide power supply of the electrical appliance will produce electromagnetic interference, and if it is serious, it will also produce noise.

3.Ordinary power supply: Once the ordinary power supply of the electrical appliance cannot adapt to the wide voltage range, it will cause the electrical appliance to automatically power off and shut down. In serious cases, it will even directly burn the electrical hardware.
