Power supply
1. SMPS & HVPS
The SMPS and HVPS are combined together as a single board.
The SMPS supplies DC Power to the entire system. It takes 110V/220V and outputs the +5V,
+24V to supply the power to the Main PBA.
The HVPS board creates the high voltage of THV/MHV/Supply/Dev and supplies it to the devel-
oper part for making best condition to display the image. The HVPS part takes the 24V and out-
puts the high voltage for THV/MHV/BIAS, and the outputted high voltage is supplied to the toner,
OPC cartridge, and transfer roller.
2. HVPS (High Voltage Power Supply)
• Transfer High Voltage (THV+)
- Input Voltage : 24 V DC 15%
- Output Voltage : MAX +5.0KV 5 %,(Duty Variable, no loading )
- Input contrast of the Voltage stability degree : under 3 % (fluctuating input 21.6V-26.4V)
Loading contrast : 3 % or less
- Output Voltage Rising Time : 100 ms Max
- Output Voltage Falling Time : 100 ms Max
- Fluctuating transfer voltage with environmental various : +650 V- 5 KV
- Environment Recognition Control Method : The THV-PWM ACTIVE is transfer active sig-
nal. It detects the resistance by recognizing the voltage value, F/B, while permits the envi-
ronmental recognition voltage.
- Output Voltage Control Method : Transfer Output Voltage is outputted and controlled by
changing Duty of THVPWM Signal.
• Charge Voltage (MHV)
- Input Voltage : 24 V DC 15%
- Output Voltage : -1.3KV to -1.8KV DC 3%
- Output Voltage Rising Time : 50 ms Max
- Output Voltage Falling Time : 50 ms Max
- Output Loading range : 30 M - 1000 M
- Output Control Signal(MHV-PWM) : CPU is HV output when PWM is Low
