5. ring thereof, for all kinds of wire data lines, signal lines, power lines, etc., in the ring after Anga, it can play a good impedance effect, to prevent outside intrusion hash electronic devices, but also ring the useful signal can well electronically. So how to choose the frequency of ring size, ring generally have a wide variety of sizes and models, respectively, RH / T / UF / FS and the like. A variety of standard models due to do so, most of them are used for impedance effect. Based on product performance to select magnetic frequency fence terminal, gifted by the proposed preference outer diameter of the large and small bore, the length of a long ring, because it contains more material 4 barrier type terminal tb, the more material containing impedance the better. Note Depending on the product to match the performance of the magnet relative frequency. 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 3K ring fence terminal block, more sensitive to temperature rises double fence terminals, 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.
