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

Fluorescent electronic ballasts, in the switching circuit between the respective substrate and the emitter of the two transistors are respectively connected with a protection diode; one end of the filament other end, and the rectifier bridge output by a series resonant circuit in the high-frequency inductor coilthe resistance of the partial pressure, the partial pressure of the filter capacitor, the midpoint of the filter circuit in contact electronic ballasts. Supporting the use of fluorescent tubes can increase the life expectancy doubled, fluorescent lamp circuit than using magnetic ballast circuits power saving by 30%, and normal voltage range of 160-250V ballast itself does not exceed 30 ° C temperature rise. Cross-conversion rate of high-frequency strong electric field within the lamp 50K times per second.
