Characteristic:
This model of pure sine wave inverters is a multifunctional convertible power supply adopting up to date converting technology. It adopts the most advanced control technology of SPWM, and it has a lot of characteristics such as: Precise control, isolation of input and output, security, efficiency, good reliability. They can convert 12V/24V/36V/48V DC power from batteries to 220V pure sine wave AC power, which specially can supply electricity power to families, marketplace and so on. They are also applied for cars, ships, camping, wind power supply, solar power, trains, cars, communication and so on. They have perfect intellectualized protection. They are researched and developed by ourselves with many highly technologies and intellectualized electrical components, which could simplify the fussy control and protection made by apart components and improve the reliability of inverters as well as make the operation more convenient. The degree of wave shape distortion is much better than our imagination.
Advantages:
Low voltage input model adopt original imported IR MOS tube. The current is 5.5 times of rated current.
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 the protection function start.
