• Cleaning Voltage (THV-)
- The (+) Transfer Voltage is not outputted because the THV PWM is controlled with high.
- The (-) Transfer Voltage is outputted because the THV-Enable Signal is controlled with
low
- The output fluctuation range is big because there is no Feedback control.
- Input Voltage : 24 V DC 15%
- Output Voltage : -1KV 15%
- Output Voltage Rising Time : 100 ms Max
- Output Voltage Falling Time : 100 ms Max
• Developing Voltage (DEV)
- Input Voltage : 24 V DC 15%
- Output Voltage: -200V to -600V DC 3%
- Output Voltage Fluctuation range: PWM Control
- Input contrast of the output stability degree : 3 % or less
Loading contrast : 3 % or less
- Output Voltage Rising Time : 50 ms Max
- Output Voltage Falling Time : 50 ms Max
- Output Loading range : 10M - 1000 M
- Output Control Signal (BIAS-PWM) : the CPU output is HV output when PWM is low.
• Supply
- Output Voltage : -400 V to -800V DC 5%(ZENER using, DEV )
- Input contrast of the output stability degree : under 3 %
Loading contrast : 5 % or less
- Output Voltage Rising Time: 50 ms Max
- Output Voltage Falling Time: 50 ms Max
- Output Loading Range: 10 M - 1000 M
- Output Control Signal (BIAS-PWM): the CPU is HV output when PWM is low.
3. SMPS (Switching Mode Power Supply)
• AC Input
- Input Rated Voltage: AC 220V - 240V AC 110V - 127V
- Input Voltage fluctuating Range: AC 198V - 264V AC 99V - 135V
- Rated Frequency: 50/60 Hz
- Frequency Fluctuating Range: 47 - 63 Hz
- Input Current: Under 5.0Arms / 2.5Arms (But, the status when lamp is off or rated voltage
is inputted/outputted )
