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

The fluorescent ballasts interrupter protection circuitry, including electronic ballasts, and connected with the electronic ballast fluorescent lamps, a fluorescent interrupter protection circuit is also connected between the electronic ballast and fluorescent. Fluorescent interrupter said protection circuit includes a delay cutoff circuit and filament interrupter circuit, delay closing the output terminal of the circuit with the electronic ballast is connected and connected to the interrupter circuit with the lamp through the filament. The fluorescent lamps lit filament fully preheated, greatly extend the service life of the filament, improve equipment performance and instant impact resistance; automatically illuminating the filament power failure, so that the the Filament "zero current" state, greatly reducing the temperature of the fluorescent work, reduce the loss of the circuit and the fluorescent lamp, and to improve the utilization of energy, effectively avoiding the occurrence of the fluorescent light darkening.
