About the RS 2048CJ
The RS 2048CJ is a power triode manufactured by Thomson / Thales. Thales RS 2048CJ water-cooled metal-ceramic triode widely used as an RF end stage tube in industrial CO₂ laser cutting machines, RF generators, and induction heating equipment.
Key ratings of the RS 2048CJ include tube type Triode, construction Metal-ceramic, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are CO₂ laser cutting machine RF end stage, industrial RF generators, induction heating systems, RF power amplifiers and industrial heating applications. Notable features: water-cooled RS end stage triode, metal-ceramic construction, CO₂ laser machine compatible 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.
