Vehicle-mounted inverter is a kind of power product working in high current and high frequency environment, and its potential failure rate is quite high.
Therefore, consumers must be cautious when buying. Firstly, the output waveform of the inverters should not be lower than quasi-sinusoidal waveform; secondly, the inverters should have complete circuit protection function; thirdly, the manufacturers should have good after-sales service commitment; fourthly, the circuits and products have passed the test for a period of time.
1.In addition to the price factor, the main consideration in choosing on-board power supply is the requirement of input voltage and output power of on-board power supply. In addition, because the power of various electrical appliances varies greatly, the principle of choosing on-board power supply according to the use needs is adequate.
2.According to the types of electrical appliances used, it is necessary to choose the appropriate vehicle power supply. For resistive appliances, square wave, correction wave and sine wave can be used together. For inductive appliances, sine wave inverters must be selected.
3.Square-wave/corrected-wave inverters can not carry inductive and capacitive loads, can not drive air conditioning, refrigerators, and can not provide power for high-quality audio and television. Strictly speaking, square-wave/modified-wave inverters will affect the service life of electrical appliances. These problems will not occur when using sine-wave inverters.
4.Generally, the cigarette lighter insurance in a car is 10A or 15A (10A is mostly old or imported), which indicates that the on-board inverter power supply used in a car is 120W or 180W. If high-power inverters (over 180W or 200W) are needed, it is necessary to see if there is a battery clamp in the package. The use of high-power Inverters without battery clamp in cars will be limited.
5.Generally, the on-board power supply will be insured at the end of the cigarette lighter. When purchasing automotive articles, Qiqiwang reminds us that it is necessary to open and check that the insurance does not match the insurance of the automotive cigarette lighter (theoretically less than or equal to the insurance of the cigarette lighter), so that the insurance of the cigarette lighter can play a role. On the contrary, the insurance of the automotive cigarette lighter will burn out and cause unnecessary trouble.
