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

Metal halide electronic ballasts,the power supply filter circuit, the second power supply circuit, coupled to the power input filter circuit, DC step-up and constant voltage circuit, the half-bridge high frequency invertercircuit, the current PWM control circuit, and the resonant ignition circuit. The lighting metal halide lamp electronic ballast, using a digital circuit to control the lamp operating state of the electronic ballast output power does not vary with the variation of the characteristics of the lamp, to ensure that the light output of the lamp effective to solve the acoustic resonator, power and color temperature drift drift; using the battery, such as the DC power supply provided by solar cells, can replace part of the existing lighting equipment, save a lot of electricity consumption and transportation and other expenses to save energy .Metal halogen lamp electronic ballast comprises a filter, a rectifying circuit, the power supply circuit, further comprising a the upconverting circuit composed by the power factor correction chip, transformers, FET power output tube, and by a programmable high-power fluorescent dedicated chip, field-effect power output tube, the inductor is composed of a electronic ballast circuit.
