2. DC Output Circuit

This circuit converts the AC voltage input from the inlet to each DC voltage (+24V, +12V, -12V, +5V, +3.3V) and delivers it to each part of the machine. Turning on the main switch causes the supply of all DC voltages to begin.

Each DC voltage is supplied or cut off when the Power Save mode is activated or the following covers are opened or closed as shown in the table below.

DC Voltage	Voltage	In Power Save mode	Front Cover Side Cover

Output Protection

An overcurrent and an overvoltage protective circuit are configured for each DC voltage output. If the output is shorted for some reason or an abnormal condition occurs in a circuit, these circuits prevent overcurrent and overvoltage from flowing through the entire circuitry of this machine.
