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

The fluorescent Ballasts by the current circuit. By two capacitors and three diodes comprise the primary by the current circuit, is connected in the the usually electronic ballast control circuit between the bridge rectifier and the high frequency generating. Matched the auxiliary by the current circuit consists of two capacitors and two inductors double π common mode rejection high frequency filter circuit connected in series between the bridge rectifier and AC power input, another capacitor in parallel with the bridge between the positive and negative terminals of the rectifier DC output. Electronic ballasts circuit by the current, three-phase neutral current, line power factor improve grid harmonic interference reduction resistant power overvoltage ability, greatly improved the reliability of electronic ballasts.
