1. The product selects industrial-grade chip, built-in multiple intelligent protection functions. 2. Power life and use temperature, the lower the temperature, the longer the life; module using aluminium base plate, heat dissipation performance is far ordinary composite board, the corresponding life is also greatly increased 3. Product performance and stability of the price is high, in the same power to use, higher efficiency, lower heat generation 4. appearance, high sensitivity and long service life. 5. The product can be widely used in industrial power supply, control system, solar power supply equipment, electric car converter, lighting circuit and other security applications. Input voltage: 110V (buck type) Output voltage: 5V Output current: less than equal 5A Maximum output power: less than equal 60W (current less than equal 5A) Conversion efficiency: less than equal 95% the smaller the differential pressure, the higher the efficiency Input and output pressure difference: equal 25V (need to pay attention) Operating Temperature: -40-+85 No-load current: 5-10mA Over-current protection: YES Over-voltage protection: YES Short circuit protection: YES Undervoltage protection: YES Heat dissipation mode: aluminium plate natural heat dissipation Attention: Power supply rated power and heat is closely related to the power to do the more power, that the design of heat dissipation and component efficiency, the better the choice, that is to say, if you use the current to 2A, you choose 3A power supply and choose 5A power supply can be used, but 3A power supply temperature to be higher than the power supply of the 5A, the life expectancy also be greatly reduced. Considering the service life is recommended to choose a higher current.
