4.2.1
Power supply circuit
It is positioned in the top part of the unit and it is mainly composed by mains switch
(S1), line filter (Z1), a 24Vdc 7.5A switching mode power supply (G1), located under
the MCU board which supplies 24 Vdc to the logic boards, a 30Vdc power supply
(G2) that supplies the lift motor.
•
G2 power supply provides power to the motor control box (G3) which dirves the
up/down motor (M1). located in the lower part of the unit.
•
Safety switch S2 located in the top side of the unit (red button) cuts power to
the up/down motor in case of malfunction
•
Mains voltage is also provided to the Generator Board A2 used to generate
High voltage to the tube head.
Note
The S2 emergency switch
doesn’t cut power to the X-ray generator
or to
other circuits,
therefore mains voltage is still present
in the unit even
when the S2 emergency switch has been pressed.
The unit is delivered in an open range voltage configuration which makes it
compatible with both 115 Vac and 230 Vac mains electricity. (See paragraph 7.2)
