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

The Capacitive high pressure sodium ballasts,means a power conservation. Main hps ballast capacitor, pulse transformer, trigger circuit constituted. Ballast capacitor, pulse transformer coil connected to a 220V AC power supply, sodium lamp series, trigger circuit to pulse to pulse transformer coil current, coil induction high voltage set to sodium lamp starter after starter ballast capacitor stable sodium lamp operating current. The high pressure sodium ballast device is a capacitive load, to improve power factor compensation, and their power consumption is very small, with power-saving features.
