1 General information
1.1 Introduction
This section gives you all the necessary informations to maintaine the DC power sup-
ply module. It also specify how to modify the printer to operate on DC supply instead
of AC supply.
1.2 Principle of operation
The power supply module is constructed to operate from a battery voltage of 10.5V
DC to 32V DC to deliver the necessary voltages for the printer. The voltage conver-
siontakesplaceina“yback”switchconverter,whichiscontrolledbyacurrentmode
controller. The regulation of the output voltage is controlled via a separate winding of
the transformer, which also deliveres the power for the control circuit.
