4CPW1000KB Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – Switch tube (max regulation range 20 kV)

4CPW1000KB/X-2062M
The 4CPW1000KB is a water cooled power tet-
rode intended for use as a pulse modulator or
pulse regulator. The tube is rated for 175 kVdc
holdoff in a protective atmosphere, with a 75 am-
pere pulse cathode current rating during conduc-
tion and 1000 kilowatt anode dissipation rating
(average during the pulse). Peak anode current
capability in excess of 100 amperes for short pulse
operation is practical.
