The inverter is a converter that converts DC power (battery, storage battery) into fixed-frequency, fixed-voltage or frequency-regulated and voltage-regulated alternating current (generally 220V, 50Hz sine wave). It is used in air conditioners, home theaters, Electric grinding wheels, power tools, sewing machines, DVDs, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
In foreign countries, due to the high popularity of cars, when you go out to work or travel, you can use an inverter to connect the battery to drive electrical appliances and various tools. The vehicle-mounted inverter output through the cigarette lighter has power specifications of 20W, 40W, 80W, 120W to 150W, and the inverter power supply with higher power needs to be connected to the battery through a connecting wire.
By connecting household appliances to the output of the power converter, you can use various appliances in the car. Applicable electrical appliances include mobile phones, laptop computers, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, power tools, car refrigerators and various travel, camping, and medical emergency appliances. Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current into 220 volts alternating current.
Usage Precautions
Each inverter has a DC voltage value, such as 12V, 24V, etc. It is required that the selected battery voltage must be consistent with the DC input voltage of the inverter. For example, a 12V inverter must choose a 12V battery. The output power of the inverter must be greater than the power used by the appliance. Especially for appliances with high power at startup, such as refrigerators and air conditioners, a larger margin must be left.
The DC voltage connected to the inverter is marked with positive and negative poles, red is the positive pole (+), black is the negative pole (-), the battery is also marked with positive and negative poles, red is the positive pole (+) ), black is the negative pole (-). When connecting, the positive pole must be connected to positive (red to red), and the negative to negative (black to black). The diameter of the connecting wire must be thick enough, and the length of the connecting wire must be reduced as much as possible.
