About the CTK 15-2
The CTK 15-2 is a power triode manufactured by Thomson / Thales. Thales high amplification factor coaxial metal-ceramic power triode with 45 kW output at up to 120 MHz. Water-cooled anode and forced-air stem for continuous duty in CO₂ laser cutting and industrial RF heating.
Key ratings of the CTK 15-2 include tube type Triode, max output power 45 kW, max anode dissipation 20 kW, max anode voltage 13 kV, max frequency 120 MHz and construction Metal-ceramic coaxial.
Typical applications are CO₂ laser cutting machine oscillators, RF oscillators and amplifiers, industrial induction heating, plastic welding systems and wood gluing equipment. Notable features: 45 kW continuous RF output, high amplification factor triode, water-cooled anode and 120 MHz maximum frequency.
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.
