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

Fluorescent lamp electronic ballast, including EMC circuit, the rectifier filter circuit and the inverter circuit, characterized in that the inductance L of the inverter circuit is connected to one end of the other end of the inductance L of the second filament lamp foot and one end of the fourth capacitor C4 , the primary winding of the pulse transformer RT one end B1 of the first filament lamp foot, the other end of the fifth capacitor C5, the other end of the fifth capacitor C5 to the fourth filament lamp foot, the other end of the fourth capacitor C4 light the third tube filament feet and rectifier filter circuit load feedback input. The advantage of the present invention is to improve reliability while for the lamp provides good working conditions, but also to further improve the energy use, while products easily reach 3C standards, showing a filament current is small (right), the oscillation frequency stability, good electrical parameters, stable and reliable performance.
