P1910 - Description
The P1910 PFC (Power Factor Correction) power sup-
ply board generates the supply voltages for the unit.
This board works with mains voltages between 100VAC
to 240VAC, 50/60Hz.
The board produces the +380Vdc for the generator
board. The board also has auxiliary fl yback converter
that produces the lower raw voltages for the L1500
power supply board.
The major features of the board:
- the supply voltages do not depend on the line volt-
age (PFC)
- it supplies voltages +380VDC and +17VDC (against
HVGND)
- it supplies voltages +27.5VDC, -15VDC and
-20VDC (against GND)
- it monitors the line voltage (FMON) and PFC middle
circuit voltage (PWR_OK)
