Supply

2.4.1 Low-voltage power supply

The power supply uses a switching regulation system to generate the regulated DC power
(+5V and +24V), which are converted from the AC line.

The regulated output and the production code of each power supply are listed below;

Regulated Output

Production Code

+3.3V / 1.5A
+24V / 2.4A, +8V / 0.8A

100V: SRP1828UC
200V: SRP1829EK

2.4.2 High-voltage power supply

The high-voltage power supply generates and outputs the voltages and currents for the
charging, development and transfer functions.
