HVPS SpecificationAs for the developing voltage, the DC voltage and AC voltage are overlapped and output from an output terminal.There is one terminal for transcription output and + and - are switched to be output.6.17.2. CHG-BIAS (Charge BIAS)/GRID/ UNITWhen IC300 turns on the transistor Q506, CHG REM becomes “L”, and Charge BIAS (200μA) is output from CHG OUTPUT.GRID BIAS is generated by the current flowing in the GRID circuit via charge wire and GRID.Charge (CHG) Grid Developing DC Developing AC Transfer (TRA) - Transfer (TRA) +Output Characteristics Constant current Constant voltage Constant voltage Constant voltage Constant current(Variable)Constant voltageNominal Output Voltage 4.35KV 475±10V 230V±15V(50~300V)PWM20%300MΩ/220pF330V±15Vp-p34KHz100MΩ(-1.48KV)785V±100VNominal Output Current 200±15μA(19.4MΩ)200μA 0.73μA------14.8μA±1μA(0μA~25μA)PWM 35%1000MΩ(0.8μA)Load Range 18.1MΩ~20.6MΩ ----- 100MΩ~2000MΩ ----- 33.8MΩ~284MΩ 10MΩ~1000MΩConstant CurrentRange4.1~4.6KV ----- ----- ----- -0.5KV ~ -4.2KV -----
