15. Lamp Power Supply R7633705
8 Digital Inputs
FAN_OK From the fan drivers on the R7632113 module. Is high when the fans are switched
on and will become low when either of the internal fans fails.
MAINS_HIGH Is high when the mains input is in the 230V range.
PFC_OK Is high when the PFC is switched on and shows no malfunction.
LPS_OK Is high when the LPS is switched on and shows no malfunction.
SMPS_OK Is high when the internal LV SMPS on the R7632113 shows no malfunction.
8 Digital Outputs
ERROR_OUT Drives the red LED D121 (ERROR) via Q122 (on sheet 1/5).
LPS_ON A high level switches on the LPS via optocoupler I300 on sheet 3/5.
PFC_ON A high level switches on the PFC via optocoupler I300 on sheet 3/5.
TRAFO_RANGE A high level modifies the step down ratio of the LPS trafo on the R7632113 for
the high lamp voltage range.
MAINS_RANGE A high level switches the module to the 220V-only 3kW range a low level switches
the module to the 110/220V 1.5kW range.
PFC_LED Drives the green LED D231 (PFC_OK).
LPS_LED Drives the green LED D230 (LPS_OK).
BOOST_ON
A high level switches the boost voltage generator on the R7632113 module on.
8 Analog Inputs
IS Sense signal from the R7632113 module, sensitivity: 0.04V for 1A lamp current.
VS Sense signal from the R7632113 module, sensitivity: 0.1V for 1V lamp voltage.
TEMP_HTSNK_PFC Analog voltage that represents the temperature on the PFC heatsink. Analog optocoupler I320
on sheet 3/5 couples this analog voltage from the primary to the secondary.
TEMP_TRAFO Analog voltage that represents the temperature on the LPS trafo on the R7632113 module.
TEMP_HTSNK_LPS Analog voltage that represents the temperature on the LPS heatsink. Analog optocoupler I330
on sheet 3/5 couples this analog voltage from the primary to the secondary.
PFC_OUT_S Sense signal from the PFC output, sensitivity 0.01V/V. Analog optocoupler I310 on sheet 3/5
couples this analog voltage from the primary to the secondary.
TEMP_RECT_SEC Analog voltage that represents the temperature on the sec rectifier heatsink on the R7632113
module.
BOOST_OUT_S Sense signal from the R7632113 module, sensitivity: 0.025V for 1V lamp voltage (see voltage
divider on sheet 1/5).
3 PWM (pulse width modulated) outputs
DIM the PWM signal is integrated with R257 and C253 to an analog signal (1 to 5V). This voltage controls
linearly the dimming of the LPS output. With DIM = 0V the output power is at maximum (1.5kW or 3kW,
depending on the level of Mains_Range.
With DIM = 5V the output power is reduced to zero.
