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

Random noise, with sawtooth composite FM Metal Halide Ballasts,High-intensity discharge HID metal halide lamp energy saving electric light source technology, specifically a random noise, with sawtooth composite FM metal halide ballast. With electromagnetic interference suppression filter EMI main power rectifier circuits, active power factor pre-adjustment circuit APFC DC power supply and control circuit, self-oscillating pulse generator, the drive of the half-bridge or full-bridge, half-bridge or full-bridge switches inverse modulation of the starting circuit, characterized in also has a random noise generator, a sawtooth generator, the abnormality detection protection circuitry.metal Halide ballast having a sawtooth cycle change between coarse and fine adjustment double random noise disturbance characteristic around the center frequency changes, enhanced inhibition lamp discharge arc so that it can not form the standing wave, to avoid the effect of the acoustic resonance and floating arc significantly improve and has a constant power characteristics. Poor contact in the lamp, lamp aging such as the failure, abnormal protection can be obtained.
