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

Fluorescent electronic ballasts, the electronic circuit of 50Hz or 60Hz power the rectified DC power, and then driven to self-oscillation transistor to turn on - turn off the exchange to generate high-frequency power supply, and the inductorseries resonant capacitor, resulting in a high voltage to excite the fluorescent lamp starter, and has automatic protection circuit when replacing the lamp or lamps damaged, it will automatically stop the electronic ballasts action, rather than produce a high voltage, so as to avoid the danger.
