Frequency Converter

Zhejiang L&L Technology Co.,Ltd. is a professional China frequency converter Manufacturers and China frequency converter suppliers with high quality. The company is mainly engaged in the research and development, production and sales of frequency converter, environmental protection equipment, and new energy. The main products cover the fields of industrial control, environmental protection, new energy, etc. The main products cover industrial automation products serving various fields, such as frequency converter ,which price is lowly.

What is the frequency converter? Frequency converter outputs the AC power to pure sine wave after the transformation of AC→DC→AC, the output frequency and voltage can be adjusted within a certain range. Frequency converter is quite close to the ideal AC power supply, so more and more countries use it as standard power supply to provide the best power supply environment for electrical appliances, so as to assess the technical performance of electrical appliances.

The frequency converter of L&L is a high-performance frequency converter. It adopts the international leading vector control algorithm, including three control modes: V/F, PG-free vector, and closed-loop vector to achieve high-performance and high-precision motor drive. The frequency converter further strengthens the reliability of the product and the adaptability of the environment, as well as the customized and industrialized design, which can better meet the needs of various transmission applications. 

The frequency converter has three control modes: vector control without PG (SVC), V/F control, closed-loop vector control, and supports a variety of frequency setting methods: digital setting, analog setting, PID setting, communication setting, etc. ; The input and output terminals of the frequency converter are freely programmable, and users can combine a variety of working modes according to their needs;The frequency converter has the function of skip frequency control to avoid mechanical resonance and make the system more stable and reliable; the frequency converter has a variety of fault protection functions: Current, overvoltage, undervoltage, overtemperature, phase loss, overload and other protection functions.
