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

Frequency constant power metal halide ballasts, the active power factor correction circuit, current-fed push-pull type oscillator circuit, output circuit isolation, constant power control circuit and a DC high voltage trigger circuit constituted. Active power factor correction circuit input via the rectifier is connected with the low-pass filter, the output current is fed via a push-pull type oscillator circuit with isolated output circuits and DC high voltage trigger circuit phase, current-fed push-pull oscillator circuit by type constant power control circuit with active power factor correction circuit is connected. The use of high-frequency electronic ballasts circuit means to achieve constant power metal halide lamp starting and normal operation, the main feature is an effective solution to the "Acoustic Resonance" issue, the grid voltage instability in the insurance to obtain a constant power metal halide lamps, when the metal halide lamp lamp ballast output voltage is not the same as the same time, with the energy-saving effect.
