Our R & D power sine wave filter has been tested s

Our R & D power sine wave filter has been successfully tested, can completely replace imported similar products abroad, is reduced to half price, has been put into use in the field stage.

Related technical documents. See below:

Sine wave filter is applied to improve the quality of electric energy, through the LC loop filter can effectively filter the harmonic inverter itself, at the same time because of the inductance is relatively large, can effectively extend the inverter and the electrical distance, to prevent accidental damage to equipment caused by the current and voltage.

1: test voltage three-phase 380VAC, 50HZ.

2 installation methods: open mounted on the panel, or installed in the standard distribution cabinet.

3 applications: submersible pump, low driving voltage to the power supply, the medium voltage motor of HVAC equipment, wind power generator, in between the original output voltage waveform and motor and inverter high range up to 15000feet, mixed load etc..

The 4 harmonic test:

(1) 5 harmonic content testing process: Min = 0%, Max = 4.83%;

(2) 7 harmonic content testing process: Min = 0%, Max = 4.03%;

(3) 11 harmonic content testing process: Min = 0%, Max = 3.83%.

A 5 carrier frequency test:

(1) the minimum carrier frequency: 1kHz

(2) the maximum carrier frequency: 12kHz

The 6 overload ability test: 150%RMS1 minutes, 200%RMS10 seconds.

7 noise test: standard configuration can filter noise 2 meters -- 56dB-A.

The 8 voltage and current waveforms: voltage and current waveforms sine wave filter in front of the.
