The VPW2827A6 CW EIK power supply provides all required electronic power conditioning to safely operate a CPI CW Extended Interaction Klystron.
A minimum configuration RF sub-system would consist of a CW power supply, an appropriate EIK cooling unit, a CW EIK and associated RF components.
The CW EIK power supply processes AC power input at connector jack (or line cord) J1 and supplies all necessary EIK operating voltages at (high voltage connector) J3. EIK interlock functions are enabled through (low voltage connector) J2. The supplied EIK remote connection and mounting unit connects to J2 and J3. Alternatively, a customer designed and manufactured remote connection can be substituted.
In standby mode, current is provided to the EIK filament to facilitate cathode warm-up to operating temperature.
After the high voltage delay (filament warm-up) period has expired, cathode high voltage ("OPERATE ON") may be applied; regulated DC cathode and collector voltages are then applied to their respective EIK electrodes.
In the OPERATE mode, anode voltage will be present at the ANODE DIVIDER terminal and the EIK will be conducting nominal cathode current (RF capable conditions).
However, if utilizing the regulated anode terminal, cathode current is not supplied to the EIK until "RF ON" applies anode high voltage.
Internal (system) and external (cooling, safety) interlocks must be satisfied for high voltage operation.
All front panel controls (except for "MAIN POWER") and indicators may be implemented through the RS-422/RS-485 serial communication connector.
