About the CTK 5-1
The CTK 5-1 is a power triode manufactured by Thomson / Thales. Thales coaxial metal-ceramic power triode with 10 kW RF output for industrial heating, plastic welding, and RF oscillator applications.
Key ratings of the CTK 5-1 include tube type Triode, output power 10 kW, max frequency 120 MHz, construction Metal-ceramic coaxial, cooling Forced air and cathode Thorium tungsten.
Typical applications are industrial RF heating, plastic welding, wood gluing systems, RF oscillators and induction heating. Notable features: 10 kW output power, coaxial metal-ceramic build, high-µ design and thomson/Thales proven construction.
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.
