Description
The RS3040CJ is a RF power triode designed for dielectric heating applications such as textile, food and paper drying. This tube uses a coaxial design and metal-ceramic technology. This triode may be operated in CW or pulse modes. Parameters for operation in pulse mode depend on each equipment characteristics. Contact us for specific information. The RS3040CJ is a water cooled triode.
