300W~8000W Pure Sine Wave Inverter Charger for Car and Home

300W~8000W Pure Sine Wave Inverter Charger


Features:

1. High Efficiency

2. Low Interference

3. Turbo Cooling Fan

4. Soft Operation

5. LED Indicators

6. Precision Output Voltage Regulation & Filtering

7. Optional Remote Control Switch



Advantages:

1. Low voltage input model adopt original imported IR MOS tube. The current is 5.5 times of rated current.

2. Its low voltage input connection adopt high frequency low resistivity electrolytic
Capacitor. However ordinary capacitor will explode if the temperature become very high.

3. Every transformer has independent fuse protection. If there is a MOS tube break down, then the fuse will break fast. So that will not effect other MOS tube to break.

4. All the protection signal adopt monolithic processing. Circuit is simple and stable.

5. Input and output are isolated to ensure the operation stability

6. Output circuit adopt convertible circuit. `The SPWM signal produced by Single Chip Microcomputer drive the A3120 optical coupler. Then the optical coupler isolated drive the output through IGBT tube. Adopt negative pressure to cut off IGBT to eliminate Miller effect, so the output is more steady.

7. The whole design adopt patch technology. The circuit is simple and steady.

8. Allow ON/OFF button controlled by remote control switch,

9. LED indicate and alarm notice before the protection function start.
