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

Fluorescent lamp electronic ballasts, including a full-bridge rectifier, and full-bridge rectifier connected PFC module, connected to the half-bridge inverter module with PFC module also includes control with MCU connected with the PFC module, theof said microcontroller generates a PWM waveform control transistor in the power the half-bridge inverter modules opened and closed, the DC power into high frequency alternating current to maintain lamp work; the soft-start fluorescent lamp using a thermistor can be preheated, can effectively prevent the lamptube ends black, using the microcontroller to generate the PWM waveforms to control the power transistor is opened and closed, the DC power into high frequency electronic ballasts alternating current. Better able to sustain the work of the lamp.
