China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Electronic ballasts of fluorescent lamps with constant current regulator, an increase in the power input and the rectifier between varistor R7, capacitors C6, C7, C8, and common mode choke ring B2 consisting of anti-interference and harmonic suppression circuit, a total ofmode choke ring B2 two coils, equal to the number of turns, the wound in the opposite direction. BG1, BG2 the base and emitter between the connected across a capacitor C9, C10, equal capacity in the power transistor. The starter capacitor C5 and then the a thermistor R8. The advantages: reducing pollution on the grid, anti-interference, stable performance, long lamp life.
