About the ITL 12-1
The ITL 12-1 is a power triode manufactured by Thomson / Thales. Thales ITL 12-1 forced-air-cooled metal-ceramic triode with 33 kW output at up to 120 MHz for industrial RF heating, pulse oscillators, wood gluing, and plastic welding.
Key ratings of the ITL 12-1 include tube type Triode, max output power 33 kW, max anode dissipation 12 kW, max frequency 120 MHz, construction Metal-ceramic coaxial and cooling Forced air.
Typical applications are industrial RF induction heating, pulse oscillator applications, wood gluing systems, plastic welding and high-frequency dielectric heating. Notable features: 33 kW RF output power, forced-air cooled, 120 MHz maximum frequency and 12 kW anode dissipation.
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.
