Goldpower GPAD111M3.8-1A Switching Power Supply

Introduction: The GPAD111M3.8-1A is a custom power supply manufactured by our company. This power supply has a wide input voltage range of 90~264Vac, and a single output power supply of 110W. The power supply is designed with output to short-circuit protection, over-current protection, and output over-voltage protection. The entire power supply is designed in strict accordance with the requirements of safety regulations and meets the requirements of safety standards for information technology equipment.

Safety Rules:

1. The power input port has high voltage and cannot be touched by hand.
2. The power supply is a product with a large leakage current, please ground it reliably before powering on.
3. It is strictly forbidden to operate with high voltage and alternating current in thunderstorm weather.
