1. Low-voltage power supply circuit
The DC power supply of the main unit is generated by the DC power supply PCB.
The DC power supply PCB converts the input AC power supply into DC+24V,
DC+12V, DC-12V, and DC+5V, and supplies each of the internal electrical loads.
An overview of the DC power supply is shown in the table below.
