Column:Industry News Time:2021-02-22
Power inverter (vehicle power supply) is a convenient power converter that can convert DC12V direct current into AC220V alternating current which is the same as mains power. It is used by general electrical appliances.

1. What is a high frequency inverter?


   Power inverter (vehicle power supply) is a convenient power converter that can convert DC12V direct current into AC220V alternating current which is the same as mains power. It is used by general electrical appliances.


2. What is the situation in the domestic and foreign markets?


   power inverters are generally welcomed in foreign markets. In foreign countries, due to the high popularity of automobiles, inverters can be used to connect car batteries to drive electrical appliances and power tools to work when working in places where there is no electricity or when traveling.


3. Why promote this product in China?


After China entered the WTO, more and more private car purchases in the domestic market. Therefore, the power inverter as a DC-to-AC power converter used in car movement will bring convenience to your life and is also a must for car owners. Supplies.


4. Can the power inverter only be used in vehicle systems?


  Power inverter is not only suitable for vehicle-mounted systems, as long as there is a DC12V power supply, you can use a power inverter to convert DC12V to AC220V alternating current, which brings convenience to your life. 5. How is the high and low voltage alarm and shutdown function reflected?   The red LED lights up when the power inverter high and low voltage alarms and shuts down, and there is an alarm sound.


6. What is the battery protection function of the power inverter?


   When the battery is used by the power inverter, the battery voltage drops to 9.5V and the power inverter will automatically shut down to ensure that the car can start normally and the battery will not be damaged.


7. How does the power inverter realize the battery protection function?


  The power inverter relies on the internal electronic circuit to automatically realize the battery protection function. 8. What is the most common failure? How to exclude?  When using the power inverter, if there is a shutdown or alarm, check the following items:

  1) Whether the power of the driven electrical appliance exceeds the rated power value of the inverter.

   2) Whether the power inverter is well connected to the battery and electrical appliances.

  3) If it is stopped during use, whether it is a temperature alarm, at this time, it can be used continuously after stopping for a period of time.


What should be paid attention to?


   When using a power inverter, pay attention to the voltage value of the battery power supply system, and read the instructions carefully before use.
