| Remarks | (1) Measurement of ripple and noise: Using a 12″twisted-pair line with a capacitor of 0.1uF and 47uF in parallel at the terminal,the measurement is carried out at 20MHz bandwidth.(2)Efficiency is tested at the input voltage of 230VAC, rated load and 25oC ambient temperature.Accuracy:including setting error,linear adjustment rate and load adjustmient rate.Test method of linear adjustment rate: testing from low voltage to high voltage at rated loadLoad adjustment rate test method: from 0%-100% rated load.The start-up time is measured in the cold start state, and the fast frequent switch machine may increase the startup time.When the altitude is above 2000 meters, the operating temperature should be lowered by 5 /1000. | |||||||||
A switching power supply is a power supply device that converts alternating current into direct current. Its advantages are high efficiency and energy saving, stable output voltage and so on. Switching power supply is suitable for a wide range of fields, let’s take a look at it in detail.
1.Computer field
In different computer equipment, switching power supply is widely used. For example, in a desktop computer, a switching power supply of 300W to 500W is generally used for power supply. On the server, a switching power supply of more than 750 watts is often used. Switching power supplies provide high-efficiency outputs to meet the high power demands of computer equipment.
2.Industrial equipment field
In the field of industrial equipment, switching power supply is an essential power supply device. It helps management control the normal operation of equipment and also provides backup power for equipment in the event of failure. Switching power supply can be used in robot control, vision power supply of intelligent electronic equipment and other fields.
3.Communication equipment field
In the field of communication equipment, switching power supply also has a wide range of applications. Broadcasting, television, communications, and computers all require switching power supplies to ensure continuous power supply and maintain state stability. The power supply of the equipment can determine the stability of communication and information transmission.
4.Household appliances
Switching power supplies are also applicable to the field of household appliances. For example, digital equipment, smart home, network set-top boxes, etc. all need to use switching power supply equipment. In these application fields, the switching power supply not only needs to meet the high-efficiency and stable output requirements, but also needs to have the advantages of miniaturization and light weight. In short, switching power supply, as an efficient and stable power supply device, has been widely used in various fields. In the future, with the continuous advancement of technology, switching power supplies will be more widely used and promoted.
