15. Lamp Power Supply R7633705
General composition
The R7633705 is the part number of the complete unit. This unit contains all necessary electronic circuits to work as an independent
power supply unit for the Xenon lamp. This includes its own low voltage SMPS for the internal circuits. On exception: the built in
microprocessor gets its supply via connector J619 from the external projector SMPS module.
It is composed of two boards:
R7632105 LPS-X Processor
Functionality on board
•
Power Factor Correction (PFC)
•
Primary circuits of the LPS
•
Feedback circuits
•
I²C Interface circuits.
•
µ-processor control of the PFC and LPS and its protections.
R7632113 LPS-X In/Out
Functionality on board
•
EMC filter with inrush limiter and bridge rectifier.
•
Internal Stand-By power supply
•
Secondary circuits of the LPS.
•
Lamp_voltage_sense.
•
Lamp_current_sense.
•
Boost voltage generator.
•
Fan Control
Visual indications LEDs
LAMP_ON
(Green LED)
comes ON when the LPS provides power to the lamp.
On
Mains volage above 85 Vac and internal low power supply is OK. The module is ready for
lamp start up.
LVPS_OK
(Yellow LED)
Off
•
Mains voltage not present or,
•
Fuse F100 in LPS module has blown up or,
•
internal low power supply is NOK
PFC_OK
(Green LED)
is ON when the PFC is switches On and functions correctly.
LPS_OK
(Green LED)
is on when the LPS is switched On and functions correctly.
ERROR
(Red
LED)
in case of an error detection, this LED comes On.
Note: if the Red LED is ON, then the PFC nor the LPS can be started up.
