SMPS AND HVPS
6.4.2 SMPS(SWITCHING MODE POWER SUPPLY)
SMPS is the power source for the entire system. It is mounted at the bottom of the
machine and consists of the SMPS area, which supplies DC power to drive the
system. SMPS also supplies power to the AC heater control area, which supplies
the power to the fusing unit. The SMPS has four output channels (+5V, +24V, and
24VS).
The SMPS supplies the following power types:
• North America: 120V
• Europe: 220V
• China (and nations with unpredictable power sources): 220V
1. AC Input
• Input rated voltage : AC 220V ~ 240V, AC 120V / AC 220V
• Input voltage fluctuating range : AC 198V ~ 264V, AC 90V ~ 135V, AC 198V ~
264V
• Rated frequency : 50/60 Hz
• Frequency fluctuating range : 47 ~ 63 Hz
• Input current : Under 5.0A/2.5A (when the fusing lamp is off and input/output
voltages are in range)
