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

Intelligent dimmable electronic ballasts includes a control circuit, the control circuit input terminal and connected to an external circuit, the output terminal of the control circuit via the RC oscillator circuit with the half-bridge inverter drive control circuit is connected to the input terminal of the AC power supply through the power supply circuit andthe half-bridge inverter drive control circuit is connected to the input terminal of the half-bridge inverter output terminal of the drive control circuit and the high-pressure gas discharge lamp HID-linked, high-pressure gas discharge lamp HID connected to the amplifying circuit and control circuit through the acquisition. The electronic ballasts determine the reference voltage of the lamp so that the lamp of the reference voltage from its power is proportional to the lamp power with a reference voltage and change, both to facilitate precise control of the lamp power to achieve dimming, and suitable for various lamps use, in addition, the utility model also has a suppression circuit, in order to avoid flicker occurs in the dimming process.
