What are the advantages of a wide input voltage range (full voltage) of AC85~265V for LED tube tubes?
The global voltage is divided into 110v 220v 277v grades. At present, the voltage range of LED tube tubes can be 85-265v, which is called full voltage, which is suitable for use in most parts of the world. It is convenient, universal, and reduces the trouble caused by different voltages. And it is a constant current source, which greatly protects the light beads and prolongs the life of the LED tube tube. The most important thing is that the low voltage 85v can also be used normally, which satisfies the use in areas with insufficient power, and the effect is quite good.
Wide voltage means that the input voltage can meet the grid voltage requirements of any country in the world, the range is: 85-265v, 277-305Vac.
Narrow voltage means that the input voltage can only be applied to the grid voltage requirements of certain countries. For example, the grid voltage range applicable to mainland China and Europe is: 176-305Vac (some only label: 176-264Vac is not wide enough); for example The grid voltage range for Japan and most states in the United States is: 80-144Vac.
The working input voltage range of LED tube tube is relatively wide (full voltage) AC85~265V. When a wide voltage is required, the output voltage should not exceed 80V, and the input voltage range can reach 85~265V. That is to say, the number of concatenations can reach 24 strings. Reduce the number of parallel connections, the working current is also reduced, and the heat generation is reduced. It is recommended to be 6 parallels/8 parallels/12 parallels. The total current can exceed 240mA. With 2835 light beads, the rated working current of the general led tube tube is 60 mA. Some factories use it up at the beginning, and the design is 60 mA. In fact, the working heat is very serious under this current. After many comparison tests, the design is 50 to 55 mA is ideal, and the recommended design is 50 mA.
Wide voltage (full voltage) AC85~265V is used for LED tube tubes, which can be applied to most parts of the world. For example, in some underdeveloped areas, the voltage is not enough. During the peak period of electricity consumption, the grid voltage is actually only a few tens of volts. It is not lit, but the LED tube tube can work normally at this time, which is very popular. On the contrary, in some areas the voltage is very high. For example, at night, the grid voltage will rise, far greater than 220v, and ordinary tube light are at high voltage for a long time, and the life of their related accessories will be shortened, so the wide voltage LED tube tube can withstand 265v voltage, which is very safe.
Therefore, the advantages of wide voltage LED tube tubes are reflected, which is much better than ordinary tube tubes. Select the voltage according to the actual local situation.
