We specialize in the production, development and research of passive harmonic filters, sine wave filters, du/dt filters, resistors, reactors and transformers.

The factory specializes in the production, development and research of passive harmonic filters, sine wave filters, du/dt filters, resistors, reactors and transformers. It is one of the earliest manufacturers of inverter braking resistors and reactors in China, and our products are well sold in more than 20 provinces and cities in China.

Since its establishment, the factory has been developing step by step to become the most extensive and influential enterprise in the industry with the business promotion concept of “strategy first, business success, management-oriented”.

It is a kind of low-pass filter, which can effectively suppress the switching frequency component of the frequency converter and eliminate the phase-to-phase output voltage of the frequency converter close to sinusoidal waveform. This reduces the insulation pressure and bearing current of the motor.

It is a double-tuned filter absorber circuit combined with reactor L and capacitor C. After special adjustment and design, it can effectively absorb and filter harmonic currents of the 5th and 7th or higher.

It can filter out harmonic frequencies higher than the carrier frequency. After installing DU/DT filter, the output of motor side is still PWM pulse waveform voltage, but the rise time and peak voltage decrease, with smaller inductive and capacitive reactance, almost no additional impedance between inverter and motor, suitable for high dynamic applications.

Our factory is a professional R & D, production of inverter peripheral products, around the harmonics generated by the inverter, inverter energy braking to develop a variety of products, mainly filters, reactors, braking units and braking resistors.

Inverter is gradually used in high power lifting and transportation equipment, so the power of braking resistor also increases, for this reason, we have developed the G Series Resistor Cabinet, the power of a single resistor cabinet can be up to 200KW, at the same time, one resistor cabinet can simultaneously accommodate a number of groups of braking resistors, resistor cabinets, compact structure, easy to lift. We have developed aluminum alloy resistors and stainless steel resistors for high environmental requirements.

Strategy first, management wins, management-oriented

We are committed to excellence in everything we do and look forward to working with you!
