A ELECTRONIC BALLAST HAVE THE PROGRAMMING INTERFACE GENERAL-USE

摘要

An electronic ballast have the programming interface general-use can be applied to various kinds of high voltage discharge lamps by using the lamp selecting display unit and the selecting unit for the kind of lamp connected to the microprocessor. The current detecting part(28) blocks the current applied in the high voltage discharge lamp. The current detector receives the current signal generated in the current sensor. All kinds of the noise and the noise signal are removed by using the phase difference amplifier. The current detector detects only the pure current value and applies the signal to the AD converter port of microprocessor. The voltage detecting portion(27) is connected in parallel with the current detector. The voltage detecting portion detects the pure voltage value and applies it to the AD converter port of microprocessor.
