Input and output AC choke reactor 30kw 220V/380V to prevent harmonic interference and short wavelength

Product Specifications

The function of input AC choke(reactor) matched with frequency inverter. Because frequency inverter often suffers from surge current and surge voltage impact, which will be seriously damaged performance and service life of frequency inverter and variable frequency drive.  so there is requirement to add input reactor in front of the frequency inverter to boycott the surge voltage and surge current, protect the converter and debugger and prolong its service life and prevent harmonic interference. And because the frequency inverter is the variable frequency speed regulation way, so when frequency inverter works, it often produce high harmonic wave and produce waveform distortion, it will affect the normal equipment use, therefore, must add AC reactor at input/output side of frequency inverter , to short wavelengths, limits the harmonic voltage and harmonic current, and improve power quality.

The input and output AC choke of China EM technology limited uses the advanced technology by the high quality silicon steel and steel line. It has low temperature, low noise, simple operation and easy management characteristics.

EMHEATER AC choke can matched with all brand frequency inverter, such as Siemens, schneider, ABB, Vacon , Danfoss, Yaskawa, Fuji, Hitachi, mitsubishi and our own EM8, EM9, EM10 series frequency inverter.

AC choke(Reactor)

Advantage Feature

1,Reducing working frequency inverter and DC speed regulator interference to other devices, like harmonic interference, waveform distortion.

2,Enhance the capability of frequency inverter resistance.  voltage unbalance degree. (Unbalance degree > 1.8% of rated voltage).

3,Improve the power factor of power supply,lower harmonic current contents in the inverter power supply.
