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

Metal halide ballasts, including filtering, rectifying circuit, voltage regulator power supply circuit further includes a boost converter circuit composed by the power factor correction chip, transformers, FET power output tube, and by a programmable high-power fluorescentdedicated circuit, effect power output tube, inductors ballast circuit.
The boost converter circuit to control the AC power supply input current total harmonic the Porch variable rate below 1%, the line power factor of 0.99, the change of 150V-260V when the input voltage of the AC power that can be output by the boost converter circuit for low ripple, stable 400V DC output voltage to ensure that the electronic ballasts circuit are driven at a constant output power, the voltage change adaptability, low failure rate, to extend the service life of the metal halide lamp.
