Power supplyOverviewLow Voltage Power Supply PCB converts DC power supply from AC power supply to supply voltage to PCBs.DescriptionThe following shows a block diagram of the power supply.• Low Voltage Power Supply PCB: Controls the temperature of the Fixing Heater of the Fixing Assembly and generates theDC power supply required by the host machine.• DC Controller: Distributes voltage provided by the Low Voltage Power Supply to respective load.When the Low Voltage Power Supply PCB is connected to the inlet, AC power supply to the Low Voltage Power Supply PCBstarts.AC power supply is used to drive the Fixing Heater. +24 V generation circuit in the power supply generates DC power voltage+24V.+3.3 V is generated from DC voltage +24 V, which is generated in the power supply, then supplied to the DC Controller and theMain Controller.DC Controller generates +5 V from DC voltage +24 V, and then supplies it to the High Voltage PCB.Voltage generated by the Fixing Power Supply PCB and DC Controller is supplied to each load.+24FFETFETFETFET+3.3FLVMFREQSNSDoor SWcircuit+3.3V +3.3U+24U+24V+24V24F ON+24F +5R+24P3.3F ONAC inputLow voltage power supplyFuseFU101+24Vgenerationcircuit+3.3VgenerationcircuitProtectioncircuitMotor PCBDC controllerHigh voltage power supplyFixing unit+5VgenerationcircuitMain controller PCBRectifyingcircuitEngine controller PCBFuseFU202Frequencydetection circuit220-240V only2.
