    Circuit description Power circuit (1) The power block is compatible with 100 to 120VAC/220 to 240VAC. (Automatically tracked) (2) The power supply section is a PRC (ON width control with constant OFF time) during P-SAVE, and operates as a pseudo-resonance circuit in the steady state. By feeding back via the photocoupler IC903 from the output voltage with the HIC (STR-G6452) flyback converter type switching IC (IC901) with built-in POWER-MOS FET and separate-exciting control IC, the voltage is constantly controlled to prevent output voltage fluctuations caused by AC...
