  • Page 26: Theory Of Operation

    THEORY OF OPERATION Overall The power supply provides three power sources to the CV-6S System. High Voltage Power - 10kV DC - 600mA Filament Power - 10V AC - 75 Amperes Position Power 15V DC - 3 Amperes (Optional) Each power supply operates independently with the addition of emission current control by the filament supply.
  • Page 27 The switching between the operational modes is performed automatically on the Gun Supply Circuit Card. The high voltage power supply initiates the switching when the high voltage is turned on and operating in its regulation window. Position Power (Optional) The position supply uses the rail voltage provided on the input to the Gun Supply Card. The position supply is low power, 15 volts at 45 watts.

  • Page 29: Control "High Voltage

    Control "High Voltage" (Optional) HV-S4 Meter Select Switch: The switch selects between power supply output voltage and power supply total current. The voltage readout maximum is 10.0kV and the current maximum is 600mA. HV-S3 Remote-Local Switch: The switch transfers the following functions to the remote interface: High Voltage ON H.V.

  • Page 31: Control "Gun

    Control "Gun" (Optional) G1-S4 Selector Switch: Provides a readout of the three gun related circuits. The emission current 0-600mA is high voltage current and requires that both the gun and high voltage power supplies be ON. The filament current 0-75.0 amperes provides a readout with Gun ON.

    Filament Transformer Module The filament power supply provides an A.C. voltage for filament operation. The frequency of operation is 34 kHz. The filament transformer provides 10 volts at 75 amperes maximum to the filament for operation. The filament transformer has a single turn secondary providing the power. The 40 mills thickness of copper connects to the two brass studs located in the G-10 output plate.

    Interconnect Cables: There are five interconnect cables in the power supply chassis that make connection between the circuit boards and the circuit boards and the jacks on the rear panel. Make sure they are in place and making connection. There are two shield ribbon cables connecting between the power supply chassis and the control. Make sure the connections are in place and bolted in position.
