Selection of switching power supply, should be a comprehensive consideration of various factors. Shenzhen Mingwei Electronics Co., Ltd. is a collection of development, design, production, sales trade and processing as one of the industrial companies. Mainly engaged in the production of AC-AC power adapter (AC to AC power adapter), AC-DC power adapter (AC to DC power adapter) high and low-frequency power transformers, power adapters, electronic switching power supply, security monitoring power supply, LED drive power supply, medical certification power supply, a small regulator, charging power supply, and other power inductors and coils. Some of our products have passed the safety certification of China, Argentina, USA, Canada, Germany, Australia, UK and Korea. We have a group of diligent and experienced technicians and business backbone, dedicated to the manufacturers, research units to provide excellent products and customer satisfaction after-sales service! Here shenzhen ming for electronic share some purchase skills, hope to help you.

1, choose the appropriate input voltage range. AC input, for example, commonly used input voltage specifications have 110V, 220V, so there are 110V, 220V AC switching, as well as general-purpose input voltage (AC: 85V-264V) three specifications. Input voltage specifications should be selected according to the area of use.

2, choose the right power. Switching power supply will consume part of the power when working and release it in the form of heat. In order to increase the life of the power supply, it is recommended to select a model with 30% more output power rating.

3. Consider the load characteristics. In order to improve the reliability of the system, it is recommended that the switching power supply operates at 50% -80% load is preferred, that is, assuming that the power used is 20W, the output power should be selected as 25W-40W switching power supply.

4, if the load is a motor, light bulb or capacitive load, when the power-on moment when the current is large, should be selected to avoid overloading the power supply. If the load is a motor should be considered when the shutdown voltage back-up.

5, in addition to the need to consider the operating temperature of the power supply, and there is no additional auxiliary heat dissipation equipment, in the ring temperature is too high a power supply needs to reduce the output. Need to refer to the ring temperature on the output power derating curve.

6, according to the application of the required selection of functions: protection functions: over-voltage protection (OVP), over-temperature protection (OTP), over-load protection (OLP) and so on. Application functions: signal function (normal power supply, power supply failure), remote control function, telemetry function, parallel connection function, etc. Special functions: power factor correction (PFC), uninterrupted power supply (UPS)

7, select the required safety regulations and electromagnetic compatibility (EMC) certification. According to the use of the situation, set out the required output voltage, current; power supply size, installation and mounting holes; how many outputs, whether the various outputs need to be electrically isolated; input voltage range; according to the ambient temperature, to determine the degree of derating of the switching power supply, the power supply power; whether the need for certification and safety standards; power supply cooling: natural cooling or forced air-cooled; electromagnetic compatibility standards.

8, try to use the manufacturer's standard power supply, including standard size and output voltage. So that the delivery period is faster; on the contrary, the special size and output voltage, it will extend the delivery period, increase the cost. 9, choose the brand. Switching power supply as the heart of the electronic equipment, the more secure and reliable operation of electronic equipment has a vital role.

So it is also important to choose the brand of switching power supply, want to know more about switching power supply information, you can consult Xiamen Eahunt Electronics.
