About the 3CX15000A7
The 3CX15000A7 is a power triode manufactured by Eimac / CPI. Large ceramic triode with 15 kW plate dissipation for high-power shortwave and medium-wave broadcast transmitters operating at HF frequencies.
Key ratings of the 3CX15000A7 include tube type Triode, plate dissipation 15000 W, max plate voltage 14 kV, max plate current 4.5 A, mu 160 and max frequency 150 MHz.
Typical applications are international shortwave broadcast, medium-wave AM broadcast, strategic HF communications and industrial RF heating at HF. Notable features: 15 kW plate dissipation, water-cooled operation, HF shortwave optimized and strategic broadcast applications.
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.
