2013 vehicle inverter interpretation of choose and buy of six points for attention
In 2013, into the New Year, the car is not just walking tool, if you have a lot of their car as a mobile home, will be installed in the car DVD audio system, car refrigerator, car air purifier, the most commonly used laptops and tablet is also is done in the car. At that time, the practicability of vehicle-mounted inverter has become one of the owners were essential to the auto equipment. Clearly the function of the vehicle-mounted inverter is to be able to put the car 12 v / 24 v direct current (DC) into 220 v alternating current (AC) for the use of general electric, is a convenient power supply converter. At present, with the growth of the auto market, car inverter type more and more, so as a smart consumers and users, we should how to choose and buy safe and practical vehicle inverter?
A, choose split type vehicle-mounted inverter
Don't know how many cyclists are used one-piece vehicle-mounted inverter, but used the owner can find many of its insufficient place. First of all, because the car cigarette lighter socket is not deep, one-piece head there is a big and very heavy, the car driving in the process of turbulence easy to cause the jitter of inverter or cancel the bad cause. Secondly, one-piece inverter plugged into the cigarette lighter socket, exposing parts is too long, the serious influence to the right shift operation, affect driving, the drivers that is worth to concern. The last point is due to the inverter type plug directly into the cigarette lighter socket, one-piece inverter can't use the back. So using split type vehicle-mounted inverter, on the driving safety and convenience to use are worthy of trust. Safety factor score 3 star
Second, the normal manufacturer production security
We will through a simple observation of a shopping product production date, trademarks and other related information, to discern between true and false. And we also need to understand that real normal car inverter, there must be a Chinese trademark and manufacturers, contact phone number, address, and can pass the qr code or barcode query to the relevant information. If not, generally can distinguish for 3 without the product, there are a lot of businesses, on a pile of leaving the country, is not worth to identify our logo, if quality problems, is also the recourse. 3 star safety coefficient evaluation
Three, use metal shell
We are very clear, vehicle-mounted inverter type converts the voltage to 220 v voltage, switch between power is very big, inevitable fever is also very large. This time, if not timely and good cooling function, also is very dangerous. Light will affect the service life of components, serious word will produce a danger of fire. Therefore, metal shell of choose and buy car inverter is very worthy of juyou thought and consideration. Is made of metal shell has good heat dissipation properties, can be very good to prevent external fire. So choose metal shell of the car inverter, safety coefficient evaluation 4 stars
Four, a full range of intelligent security protection function
This era is intelligent digital age, of course, the choose and buy of vehicle-mounted inverter must have intelligent protection function is also very important, in the use of a variety of harsh conditions, intelligent can protect your car and power. Now use vehicle-mounted inverter is generally has the switch off overvoltage, undervoltage, shut off, short circuit protection, asking protection and barrier protection, undervoltage cut-off restore function, but that is not fully achieve intelligent. Real intelligent protection, with sound and light alarm is also should, when you use on the one hand can remind you of all kinds of situations and make a response, on the other hand also can complete the intelligent protection, artificial intelligent protection function and safety coefficient evaluation 4 stars
Fifth, high power, high conversion rate
High conversion rate is not only a main indicator of on-board inverter, it is also an important index for all electrical appliances. Is one of the important indicators to measure the power efficiency. And the higher the conversion efficiency of the inverter, battery using time is longer, and the smaller inverter fever. But mark inverter conversion rates are on the market at present is empty mark to more than 90%, the index also can't test, the user can only through your calorific value to discern simply, and good inverter, in conventional load work for a long time is not hot. Therefore, high conversion rate of inverter can greatly reduce the degree of heat, protect the cars and their own digital products, safety evaluation of 5 stars
Six, the cigarette lighter plug use bakelite material
Reason is that electricity wood mass energy has high mechanical strength, good insulation, heat resistance, corrosion resistance, able to work under the condition of high temperature deformation, also won't burn. And some illegal vendors to reduce costs, without electricity qualitative lumber, it is quite a big security hidden danger. Bakelite seatand appearance is bright, and use of plastic cigarette lighter plug will look dull, without burnish. Safety coefficient evaluation of 5 stars.
