Frequency converter can transform AC mains through AC→DC→AC conversion and output pure sine wave power. It is mainly used in electronic devices with induction motor speed regulation. It is also an important device producing changeable voltage and frequency. For the adjustable frequency and voltage inverter, we call frequency converter. There is so much about the …
The technical parameters of the frequency converter are divided into the input side and output side. The technical parameters of the input side of the inverter include input voltage, phase number, frequency; the technical parameters of the output side include rated output voltage, rated current, rated capacity, capacity, frequency accuracy, frequency resolution, protection level, and …
Apply frequency converter for motor speed control, it can vary the motor speed based on actual applications, and save energy. It is mainly based on the following factors: Frequency Control System should have low self-loss and high efficiency; The motor is always kept at a low slip running, reduce the rotor losses; It can achieve …
The frequency converter is constituted by the entire circuit AC-DC-AC-filter converting device, it has been widely used. Frequency converter not only can analog output indicators of different countries, but also provide clean and reliable, low harmonic distortion, high voltage and frequency stability in the design, development, production, testing and other applications sine wave power output …
The frequency converter is a general name, more accurately name is AC power frequency converter. The entire development history of the frequency converters is the development of electronic devices. Before and after the 1980s, electronic frequency converters are mainly made in Japan. Such devices use more power crystal enlarged manner making after the 80s Chinese …
Since the world power grid index is not unified, export electronics manufacturers need to supply simulation power grid conditions in different countries, offering clean, reliable low harmonic distortion, high stability sine wave power output for engineers in designing, development, production line testing, quality assurance, life expectancy, high/low pressure simulation tests, etc. User imported original electrical …
The application of frequency converter is becoming more and more widespread, its daily maintenance management, troubleshooting processing will be frequently encountered. This article introduces the troubleshooting of a general-purpose frequency converter for reference, which can help to ensure the smooth operation of the work and save the outgoing maintenance cost. Damages on Module Analyzing The …
Learning how to select a suitable frequency converter for the normal operation of machinery and equipment electrical control systems is essential. When choosing a frequency converter, you should attention to the load torque characteristics, speed range, static speed precision, starting torque requirements, and use of the environment, and then decide which frequency converter to use. …
Long-time use of frequency converter will lead to lower quality and efficiency, resulting in a serious impact on the equipment. So we not only need to regularly replace the spare parts of the frequency converter but also need to know the correct way of replacement, in this way we are able to ensure the quality …
At present, most European & Asian countries’ civilian standard AC voltage is single phase 220V (230v, 240v), 50Hz (single-phase two-wire, power frequency 50 Hz), industry-standard is three-phase 380V (400v, 415v, 420v), 50Hz (three-phase four-wire system, three-phase three-wire system). The United States and Canada AC power supply frequencies are both 60Hz, according to American National Standard …
