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

The intelligent dimming high pressure sodium electronic ballasts, mainly by the housing and electrical components. The electrical component is included in the setting and control circuit of the ballast circuit and dimming. Mainly provided with the dimming setting and control circuit, central controller CPU, Zener diode, protection diodes, voltage dividing resistors, and the output control transistor. The central controller CPU has a pre-set time and output control transistor work in normal working condition, the work can not afford to control dimming set and control circuit of the high pressure sodium, high pressure sodium lamp only controlled by the electronic ballast , rated power, a conventional light emission luminance, when the dimmer settings and the control circuit enters the range of the working time of the set when the central controller CPU issued instruction, changing the state of electronic ballasts, driven reduce the output current, thereby reducing the luminance and power consumption of the high-pressure sodium lamps,
