LED fluorescent tube wide voltage (full voltage) 85～265V
The working input voltage range of LED fluorescent tube is relatively wide (full voltage) AC85～265V. When a wide voltage is required, the output voltage should not exceed 72V, and the input voltage range can reach 85～265V. In other words, the number of series can reach 24 series. Reduce the number of parallel connections, reduce the operating current and reduce the number of transmissions. It is recommended to be 6-parallel/8-parallel/12-parallel. The total current can exceed 240 mA. With 2835 lamp beads, the rated working current of the general led fluorescent tube is 60 mA. Some factories use it up at the beginning and design 60 mA. In fact, the working current under this current is very serious. After many comparison tests, the design is 50～55 mA is ideal, and the recommended design is 50 mA.
The global voltage is divided into several grades of 110v, 220v and 277v. At present, the voltage range of LED fluorescent tubes can reach 85-265v, which is called full voltage, which can meet the needs of most parts of the world. It is convenient and universal, and reduces the trouble caused by different voltages. Moreover, it is a constant current source, which greatly protects the lamp beads and prolongs the life of the LED tube.
