The sine wave filter NIETZ adopting trait reactor, having professional filter capacitor and power resistor, reasonable structure, waveform distortion is small, small loss and low noise characteristics, can match with all brands frequency inverter and match many sets of machines, such as wind power, oil field, water and electricity, metallurgy, etc.
 
Use our Sine Wave Filters for best motor performance and life expectancy or to improve voltage quality for alternative energy inverter applications. 
 
SINE WAVE FILTERS: 200-690 VOLTS, 50/60HZ

Electrical Feature:
 
1. To converse SPWM voltage current waveform of frequency inverter to approximate sine wave waveform (For the line load feature, the COS is greater than 0. 3 and T H D is less than 5%);
2. Protect motor insulation system, reduce bearing current, prolong service life, reduce motor noise;
3. With general asynchronous motor can replace frequency induction motor use;
4. Effectively restrain the high frequency loss and RF radiation interference, in certain occasions without to use a shielded cable, lowering the field Cable requirements;
5. We have 220 V - 690V three phase variable frequency drive system;
6. Suitable motor and inverter power range: 0. 4KW - 1600 KW;
7. Suitable frequency inverter output carrier frequency range: 1.5-16 KHz;
8. Basic frequency range: 50 / 60 Hz ;
9. Driving load forms: asynchronous motor (After special design can use for EPS \ UPS and the surrounding power supply system);
10. Heat resistant level: F grade (for reactor part);
11. Protection level: IP00 - 20. 
 APPLICATION: Motors that are controlled by variable frequency drives are subjected to higher stresses and losses caused by PWM voltage and become especially vulnerable to premature failure when the cable lengths between VFD and motor are long. Typical applications include submersible pumps, air handling units, irrigation, municipal water, lift stations, water treatment, etc. Inverter output Sine wave filters can also be used to improve voltage quality from alternative energy inverter power sources.
