What Is a Power Inverter?

Power inverter (vehicle power supply) is a kind of convenient power converter that can convert DC12V DC power into AC220V AC power which is the same as the city power. It is used by general electric appliances.

Power inverters are generally welcomed in foreign markets. Because of the high penetration rate of cars abroad, you can use it when you go out to work in places without utility power or to travel.

The power inverter is not only suitable for vehicle-mounted systems. As long as there is a DC12V power supply, you can use the power inverter to convert DC12V to AC220V AC, bringing convenience to your life. 5. How does the high and low pressure alarm and shutdown function manifest? When the power inverter's high and low voltage alarms and shuts down, the red LED lights up and there is an alarm sound.

When the power inverter uses a battery, the battery voltage drops to 9.5V, and the power inverter will

1. In the manufacture of power inverters

1. What types of power inverters?

The power inverters on the market are 140W, 450W, 800W, 1200W, 2000W, 3000W, 225W portable, 400W portable.

2. How to choose the right model?

The power inverter can be selected according to your life and work. For example: a 140W power inverter can use a 29-inch color TV and a VCD player.

450W power inverter can use general power tools.

800W power inverter can be used to drive a small microwave oven.

3 Can the power inverter use input power only from the stationary or running state of the car?

The use of input power can come from the running state of the car, or it can be stationary.

4 Can I use a power inverter to work if the car is stationary? Where does the input power come from?

When the car is at a standstill, you can use a power inverter to work. When the driven appliance is lower than 150W, it can directly obtain the output power from the cigarette lighter socket. When it is higher than 150W, use a special clip cable to connect the car battery to obtain power.

5. How to determine the available time for the power inverter to obtain power?

The battery used with the power inverter is generally measured in ampere-hours (AH). For example, the battery of 80AH divided by the power of the appliance multiplied by 10 is the usable time of the electrical equipment in the power inverter.

For example, a TV with 100 watts

80 ampere ÷ 100 watts × 10 = 8 hours

6. What is the surface temperature when the power inverter works? Are there certain security risks?

At the maximum power output of the power inverter, it is not higher than 70 ° C, and there is no hidden danger.

7. What are the protective devices for power inverters?

1) Temperature protection. If the surface temperature is higher than 70 , it will automatically shut off.

2) High voltage protection. Input voltage is 16V ± 0.5V

3) Low voltage alarm. Input voltage is 10.5V ± 0.5V

4) Low voltage protection. Input voltage is 10V ± 0.5V ^[1]
