2.1 Power Supply Circuit
2. CIRCUITRY
2.1 Power Supply Circuit
+24V
+24V is generated using the 24V AC input across pins 1 and 3 of CN401. This AC voltage is rectified
by D401, a 1SR154-400 diode and filtered by EC403 a 4700uF capacitor. The resulting DC voltage is
about +30V. This voltage is used by the buzzer and drawer solenoid.
VCC, VBB
VCC is generated using the 12.8V AC input across pins 1 and 2 of CN401. This AC voltage is rectified
by the DSA26C bridge rectifier and filtered by EC405 a 15000uF capacitor.
The resulting DC voltage is about +15.5V. It applies to the input of U401, a TA7805S Regulator IC
output voltage is 5V.
VPRN
VPRN the printer motor voltage is generated using the 12.8V AC input across pins 1 and 2 of CN401.
This AC voltage is rectified by the DSA26C bridge rectifier and filtered by EC405 a 15000uF capacitor.
The resulting DC voltage is about +15.5V. It applies to the corrector of Q403, a 2SD1415 transistor.
This base voltage controlled by ZD401. This emitter voltage is 7.6V.
VCUT
VCUT is generated using the 12.8V AC input across pins 1 and 2 of CN401. This AC voltage is
rectified by the DSA26C bridge rectifier and filtered by EC405 a 15000uF capacitor.
The resulting DC voltage is about +15.5V. It applies to the corrector of Q405, a 2SD1415 transistor.
This base voltage controlled by ZD404. This emitter voltage is 6.0V.
-Vpw (-28V)
The -Vpw circuit uses 26.5V AC across pins 4 and 5 of CN401. This AC voltage is rectified by D404, a
1SR154-400 diode and filtered by EC404. The circuit is generating the -Vpw (-28V) uses the -30V.
It applies to the emitter of Q404, a 2SA1284D transistor, and base voltage controlled by ZD402.
-Vpw is approximately -28V DC. This voltage is used by the display.
Filament Voltage (VF1,VF2)
The filament voltage, VF1, VF2 is used by the display tube.
Its AC input is 4.3V, and uses a ground reference -23V from the -28V circuit dropped across ZD403
and R409, R410, a 470 ohm resister.
