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

Solar street lighting system in high-pressure sodium electronic ballasts, characterized in that, said ballast comprising: a high-frequency ballast inductor, high pressure sodium lamp, the starter circuit. The starter circuit when a high-frequency AC square wave input frequency ballast inductor by controlling the induction loop to control high frequency ballast inductor DC square wave under high pressure sodium lamp starter; high pressure sodium lamp current detection signal forming circuit current detection signal generated by the current sensor in series with the HPS to control the starter circuit to stop it. The starter circuit equipped to prevent the DC square wave transient overvoltage breakdown protection circuit. The small size, light weight, eliminate audible noise, and to improve the overall efficiency of the photovoltaic lighting system advantages.
