About the RS 3040CL
The RS 3040CL is a power triode manufactured by Thomson / Thales. Thales RS 3040CL air-cooled metal-ceramic triode, the forced-air variant of the RS 3040CJ, for RF end stage in high-power industrial generators.
Key ratings of the RS 3040CL include tube type Triode, cooling Forced air, construction Metal-ceramic, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are air-cooled RF end stage, industrial RF generators, high-power RF heating and broadcast applications. Notable features: RS 3040 air-cooled variant, forced-air cooling, metal-ceramic construction and thomson/Thales quality.
Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
