As we said before a lot about some of the relevant knowledge Shatin magnetic connector where the good, I believe that long-term use or have used the magnet for people who know that there is interference of electronic products, plus ring can solve interference problems . Interference lurking in the air, we can not see, touched Shatin connectors, and electronic products at work, interfering signals, like mosquitoes flying, harassing us, we just lit mosquito coils can be rid of mosquitoes , mosquito coils as magnetic, the same token, electronic products interference occurs, we will add magnetic ring, can be resolved. Jiangmen 2.5K magnetic powder suitable as a direct drive 110V lights; Chi Electronic 3K ring suitable as 220V lamp. Why? The reason is 110V direct drive circuit easily lead to hot start problems; and 220V circuit does not heat startup problems. Jiangmen magnetic powder temperature changes little interference, while energy-saving lamps require 220V at high temperatures appropriate to power down, we need appropriate to reduce the transistor drive current, avoid lights burned at high temperature and pressure. Suppose the temperature rises, the transistor magnification increases, current increases, the lamp power to increase. Then you need to power down properly adjusted, the choice Zhi Tong, Sha Tin 3K ring connector contacts are more sensitive to temperature rise, BS along with elevated temperature rises, the transistor drive current is reduced, the lamp power is reduced to ensure that conflicts temperature and lamp power. Shatin connector, connector Which Shatin cheap, Xu Chong-electronic products factory by the Dongguan Shijie Xu Chong-electronic products factory provided.
