How much is the ballast of the fluorescent tube coming out
Because the ballast is in a series in the circuit, the output voltage is constant in normal circumstances, It's just that the electric light starts in an instant and produces a 600v-1500v pulse voltage that lasts about 1ms
The fluorescent lamp ballast is not to be understood by the idea of the current when it is activated in the lamp tube. The lamp tube of different wattage matches the current of the ballast of different current and the current is too bright or hard to start. Inductance ballasts, for example from 8 w15w20w30w40w when it in tubes without ballast between the output voltage and the zero line is power electricity after being connected in good tubes start according to the voltage at the ends of the lamp power different lamp in 80-110 - v, about 40 w at the ends of the tube voltage 110 v. Electronic ballast is the principle of the second inversion of high frequency oscillation. The output power is achieved by the size of the current supplied by the booster coil. The single-strand wire of the 13W booster coil is made, 25W with a two-ply line of 36W with 3 strands of 55W with 7 strands of gauze, the more power the larger the need of the current. Because of using ordinary multimeter is not suitable for testing the high frequency alternating current (ac) in maintenance electronic ballast can be ignored when the output voltage and to detect components mainly including tubes.
IME's "flash" is pretty good. They've been working with them all the time, and the quality of the product is assured. 3W's LED skylights are only 14, 5 yuan, and in baidu's search for flash, fans can find their website. Other lamps and lanterns also sell very cheap, have the day flower lamp, shoot lamp, sunshine tube, ball bubble lamp, soft lamp belt and so on
When the ballast is activated in the fluorescent lamp, the fluorescent powder is activated by high pressure, which makes the tube glow. After the completion of the ballast, the ballast will be reduced to the voltage limit, reducing the voltage to about 150V.
