Novus e 3. Circuit Boards - L1500, CCD Power Supply
Service manual 33
L1500 - Description
L1500 supplies different voltages to most of the circuit
boards in the unit. L1500 receives +27V5 and -20V from
P1910 PFC and regulates these voltages to produce
the other voltages that the unit requires.
The CCD sensor require +3.3V, +3.3V, +3V, +15V,
-9.4V, +5V.
L900 and the 3-phase stepper motor require 24V.
L1200 and peripheral electronics require a regulated
5VDC power supply.
P1910 measures mains voltage. This value is converted
to frequency signal and is then transferred to L1500
board. On L1500 board the signal is converted to DC
voltage. This DC voltage is measured by AD-converters
on L1200 CPU board.
