. Power supply circuits
.. External power supply
The switched impulse power supply circuit ANITA – V; – Hz/ V; . A. Its basic function is to generate unidirec-
tional voltage for the correct ECR function from the mains AC voltage.
.. Power supply + V
This power supply circuit powers all the logical circuits (VCC voltage), generates VRAM voltage and is also used to generate
the +. V voltage. At the core of this circuit lies the universal unidirectional voltage changer MC, containing current-
limiting fuse and thermal fuse. The changer represents the switched power supply circuit with kHz frequency that secures
high resistance to mains interference. Its efficiency allows highly effective voltage conversion and low heat loss.
.. Power supply for printer performance circuits + V
This + V power supply powers not only the printer performance circuits, but also powers the drawer opening circuits and
the power generating circuit for the journal winding motor. Factually, it is an electronic switch that switches directly the
output voltage from the external power supply.
.. Power supply for journal winding motor +. V
The +. V voltage for the journal winding motor is generated from the + V voltage. The schema contains switched power
supply KA.
