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, +3.3V, +3.3VS 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

-Inputting rated voltage : AC 220V ~ 240V AC 100~127V

-Inputting voltage fluctuating range : AC 198V ~ 264V AC 90V ~ 135V

-Rated frequency : 50/60 Hz

-Frequency fluctuating range : 47 ~ 63 Hz

-Inputting Current : Under 4.0Arms/2.0Arms (when heat lamp is off)
