Product Description
Specifications
1. Increase Drive System Reliability.2. Reduce Harmonics; Reduce Surge Currents; Reduce Voltage Doubling Effects.
EMHEATER Three Phase AC choke
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.

- JB9644-1999 Reactor for semi-conductor transmission
- Insulation Resistance: 1000VDC, insulation resistance >=100MOhm.
- Reactors are used vacuum dipping process, the high temperature bake curing. Coil has good insulation properties, the overall mechanical strength, moisture resistance;
- Coil is F, H class insulation system, greatly improving the reliability of long-term operation;
- Low temperature, low loss, low cost, utilization rate;
- The input reactor to limit the form of harmonic wave feedback circuit. They can also be reduced because of the converted DC Link Capacitor input rectifier caused by AC current and frequency; baseline reactor pressure drop UD = 2%, with a feeder unit for the drive and automatic operation of the transformer, but also for uk <1% of the system operation.
Functions:
- Reduction of harmonic wave,Improvement of the power factor.
- Over-voltage restriction and clean the power grid.
- Reducing the stress caused by noise to motorextended the life span of motor.
- Improvement of low-frequency conduction emission/sensitivity.
