What is the frequency conversion power supply: frequency conversion power supply is the AC power in the city after the AC - DC - AC transform, the output of a pure sine wave, the output frequency and voltage range adjustable. It is different from the use of motor speed control of the variable frequency speed controller, but also different from the ordinary AC regulated power supply. The characteristics of the ideal AC power frequency stability, voltage stability, resistance equal to zero, the voltage waveform is a pure sine wave (distortion free). Variable frequency power supply is very close to the ideal AC power supply. Therefore, more and more advanced and developed countries will frequency power as a standard power supply, to appliances provide most excellent power supply environment, to facilitate an objective assessment by the technical performance of electrical appliances. There are two main types of frequency conversion power: linear amplifier and SPWM switch type.
Application of frequency conversion power supply in which industries: frequency conversion power supply is mainly used for the manufacture or export of electrical products for the export of electrical products, testing, debugging and power supply for precision instruments. Widely used in home appliance manufacturing, electrical, electronic manufacturing, IT industry, computer equipment, laboratories, etc..
How to choose frequency conversion power supply: the user can choose according to their own actual load frequency power supply. The correct selection of the frequency conversion power supply is very important for the normal operation of the electric control system of mechanical equipment. Selection of inverter power supply, first of all to according to the type of machinery and equipment, load torque characteristics, speed range, the accuracy of the static speed, starting torque and the use of environmental requirements, and decide how to choose control ways and protective structure of variable frequency power supply the most appropriate. The so-called combination is to meet the requirements of the actual process of mechanical equipment and the use of the occasion, to achieve the best price performance of the application of frequency conversion power supply. The type and capacity of the load can be used to select the best understanding of the nature of the load you will want to use, and now there are five kinds of load to see the form:
1, resistive load,
2, inductive load
3, capacitive load:
4, rectifier load;
5, mixed type load;
6, electric energy feedback load. Customers in the choice of power supply to the load in accordance with the nature of the different choice of different power supply capacity.
