Engine Hardware Specifications
G186 6-12 SM
permitting environmental recognition voltage.
- Output Voltage Control Method: Transfer Output Voltage is outputted and controlled
by changing Duty of THVPWM
Signal. 10% Duty: +650V, 90%
Duty: +5KV 5%
ƒ Fuser Voltage
- Input Voltage: 24 V DC 15%
- Output Voltage: 30V to 1000V DC 30V
- Output Voltage Rising Time: 50 ms Max
- Output Voltage Falling Time: 50 ms Max
- Output Loading range: 30 M to 1000 M
- Output Control Signal (MHV-PWM) : CPU is HV output when PWM is Low.
ƒ 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 large because there is no Feedback control.
ƒ Developing Voltage (DEV)
- Input Voltage: 24 V DC 15%
- Output Voltage: -200V to -600V DC 20V
- Output Voltage Fluctuation range: PWM Control
- Input contrast of the output stability degree: 5 % or less, Loading contrast : 5 % or
less
- Output Voltage Rising Time: 50 ms Max
- Output Voltage Falling Time: 50 ms Max
- Output Loading range: 10M to 1000 M
- Output Control Signal (BIAS-PWM) : the CPU output is HV output when PWM is low.
ƒ Supply
- Output Voltage: -400V to -800V DC 50V(ZENER using, DEV )
- Input contrast of the output stability degree: under 5 %, Loading contrast : 5 % or less
- Output Voltage Rising Time: 50 ms Max
- Output Voltage Falling Time: 50 ms Max
- Output Loading range: 10 M to 1000 M
- Output Control Signal (BIAS-PWM): the CPU is HV output when PWM is low.
