About the RS 3040CJ
The RS 3040CJ is a power triode manufactured by Thomson / Thales. Thales RS 3040CJ water-cooled metal-ceramic triode for high-power RF end stage in industrial laser cutting and RF induction heating equipment.
Key ratings of the RS 3040CJ include tube type Triode, construction Metal-ceramic, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are CO₂ laser cutting RF end stage, industrial induction heating, high-power RF generators and industrial RF applications. Notable features: RS 3040 water-cooled variant, metal-ceramic construction, water-cooled anode and thomson/Thales manufacture.
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.
