Good safety performance. To meet the needs of most USB charging interface devices, more comprehensive, more applicable. Usage: switching power supply is widely used in industrial automation and control, military equipment, LED lighting, industrial equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heat and other fields. Optional power adapter required notes: German Technology Co., Ltd. Huizhou Main power adapter, switching power supply, multi-switching power supply products, set design, production and sales of high-tech manufacturing companies, products have passed CCC, CE , UL, PSE certification. The company offers a complete after sales service, our customers in this Tips: When you purchase the power adapter, note the following: (1) input voltage and input current; (2) the output voltage and output current; (3) output connector (interface) and output polarity. If the power adapter operating parameters and output connectors and the first wife of the same, it is completely different brands can be generic, and does not require the same parameters for the job, you can have a certain allowable variation range. Details can call us for details! Note also identify product quality is good or bad, the most direct and effective way to identify the power adapter can be checked by appearance. Include: rated voltage or rated voltage range, the power of symbolic nature, rated frequency or rated frequency range, rated current, the manufacturer's name or trademark, type, Ⅱ type "back" symbol, safety instructions, CCC signs and other information should identify the handwriting clear, easy to erase. I hope you can help, thank you!
