4CPL1000A Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – Pulse modulator or switch tube

4CPL1000A
This tube is designed for immersion in cooling a
liquid dielectric and can dissipate 1,000 watts.
In air with proper cooling, plate dissipation is
300watts. The 4CPL1000A mounting is optional.
This tube is rated to operate at an anode poten-
tial up to 15 kVdc when immersed in the recom-
mended coolant. When immersed, the rating is not
altitude dependant.
