Chip mounter equipment's power supply circuit

The utility model discloses a chip mounter equipment's power supply circuit, including first diode, a filter module, power voltage reduction and stabilization module and the 2nd filter module who connects gradually, outside switching power supply's output voltage is handled by a filter module filtering behind first diode rectification to among the input power voltage reduction and stabilization module, power voltage reduction and stabilization module converts outside switching power supply's output voltage step -down into first voltage earlier, , the steady voltage exports stable first voltage after handling, later step down first voltage and export second voltage after the conversion, carry out filtering through the 2nd filter module and handle output second voltage, messenger chip mounter equipment's available voltage includes outside switching power supply's output voltage, first voltage and second voltage are three kinds, and stabilization of output, each circuit module does not receive switching power su
