Product Description:

1. Structure of Portable Pure Sine Wave Inverter Model IMP400P

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/24 DC current from batteries to 220V pure sine wave AC current, which specially can supply electricity power to families, marketplace and so on. They are also applied for cars, ships and camping widely. They have the function of 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. This mode of inverters is fairly applicable in family, wind power supply, solar power, trains, cars, communication and so on. The degree of wave shape distortion is much better than our imagination.


2. Main Features of Portable Pure Sine Wave Inverter Model IMP400P

·  Protection Function
The protection of overload: When many loads are connected to the inverter and the total power exceed 125% than the permitted loading power, the inverter will stop working automatically within 20 seconds. At the same time the red LED will get light, the inverter is in the state of protection. Until you reduce the load and restart the inverter, it will work normally.

·  The protection of short circuit: Same as the protection of overload.

·  The protection of thermal: Due to many loads, long working time or bad ventilation the temperature inside the inverter will be increased. When it is over 80℃, the red LED will get light and the inverter will stop working in the state of protection. Suggest you to reduce the loads, and improve the ventilation environment, then restart the inverter after the temperature fall to below 80℃.

·  The protection of low voltage: when the voltage of the battery de-escalates till the point of closing, the red LED light goes on and the inverter will stop working. Inverter will come to work till charging voltage of battery goes up to restore point.

·  The protection of over voltage: When the input voltage over the safety voltage battery voltage, output will be cut off and the inverter stops working. As the input voltage turn to normal, the inverter will start to work automatically.

·  The protection of conversed connection: If the connection were conversed, the fuse will be burned. The inverter will work normally until you replace the burned fuse with new fuse. Although our inverter has the protection of conversed connection, users can not make the connection conversed on purpose because it is possible to cause bad effects on person or the equipment.
