Typical Operation

ModePlate VGm (µmhos)Rp (Ω)µPlate mA
Bi-phase half-wave (2 valves)16000 V———11000 mA
Single-phase full-wave (4 valves)32000 V———11000 mA

Application Notes

The cooling supply must be started before the application of any voltages. Water flow to the anode must not be less than 5 gallons per minute. Output should not be controlled by varying filament voltage. Rigid connection must be made to the anode only.
