4.4.2 SMPS (Switching Mode Power Supply)

This is the power source for the whole system. It is an independent module so that it is possible to use it for

common use. It is mounted at the bottom of the set.

It consists of the SMPS section, which supplies the DC power to drive the system, and the AC heater control part,

which supplies the power to the fuser. The SMPS has four output channels (+5V, +24V and 24VS).

There are three kinds of power, 120V exclusive (America), 220V exclusive (Europe), and 220V for China (nations

with unstable power supply).

1) AC Input

> Input Rated Voltage : AC 220V ~ 240V AC 120V / AC 220V(EXP version)

> 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 5.0Arms / 2.5Arms (When the fuser lamp is off and input / output voltages are in range)
