Q:What is the frequency converter through function?
Inverter through function refers to:The converter can temporary loss of power in the power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in state grid voltage recovery after the inverter can be immediately put into normal electric state.
Q:What is the TTK converter produced?
Mainly engaged in TTK brand inverter products R & D, manufacturing, SMT surface mount OEM processing, and agents of well-known brands at home and abroad, frequency converters and electronic components. The agent of many brands, manufacturers become the primary agent, after ten years of unremitting efforts, has formed the electronic components supply system, to meet the basic needs of all customers required inverter suction electronic components. Due to the rapid delivery, excellent reputation, has a large number of customers in East China. Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.
Q:What is the function of a frequency converter on an electric motor?
Through the frequency converter, the motor can be adjusted speed, so as to obtain the speed required by itself, and also can reduce the motor running current and save energy and reduce consumption.
Q:What are the possible causes of frequency hopping overload?
Because the overload is judged only by the current, it will happen at the start, stop, acceleration and deceleration, and constant speed operation. Moreover, the current and the asynchronous motor difference are inseparable, so the following conditions can be used for analysis and reference:
Q:What does "G" and "P" mean in the converter model?
Frequency converter (frequency transformer) is usually the use of power semiconductor devices through the role of switching the power frequency to another frequency power control device. The main circuit of the inverter can be divided into two categories: voltage is DC voltage source converter for AC inverter, the DC circuit is the filter capacitor current is DC converter; current source for AC inverter, the DC circuit filter inductance.
Q:Can 220V use frequency converter to drive three-phase motor with 380V?
If it is a star connection instead of a three phase 220V AC input, will the efficiency of the motor be reduced? Can you achieve the efficiency of the original motor 380V?
Q:Why does the frequency change when the frequency converter regulates the frequency?
That's for sure. The curve of voltage and frequency should be set according to the load condition, but after the rated frequency of the motor, the voltage is kept at the rated voltage
Q:What does "frequency" in household appliances mean?
The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;
Q:How do two inverters synchronize?
One potentiometer is used to control one of the inverters, and then the analog output of the inverter is used to control another inverter, and a potentiometer is added to the middle of the converter to adjust the proportion.
Q:Which brand of converter is better?
Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,
