TOSHIBA Industrial Magnetron E3327
TOSHIBA E3327 is a fixed frequency continuous wave
magnetron intended for use in the industrial microwave
heating applications.
The average output power is 5 to 6 kW in the frequency
range from 2450 to 2470 MHz.
And this output power can be obtained by adjusting the load
VSWR and its phase.
The tube is a packaged magnet type, and sub-electromagnet
for stabilizing and controlling the output power is also
installed in the tube. Water cooling for anode, forced air
cooling for output antenna and filter box are required.
Low pass filter for suppressing spurious leakage from the
cathode stem is set in the filter box. The output is fed into
a rectangular waveguide or into an oven directly.
FEATURES
(1) High efficiency
(2) Compact size and light weight
(3) Quick start
(4) Easy power controlling
note) Information in this document is subject to change without notice.
Total weight including magnets is 4.3 kg.
Operation can be started after 10 s preheating.
Power level can be easily varied by changing
the electromagnet current.

  • Page 4 NEGATIVE FACTORS AFFECTING THE LIFE OF MAGNETRON Life of the magnetron is strongly affected by the operating conditions. E3327 should be operated under the typical operating conditions. We also recommend strongly that E3327 is operated substantially continuously. Tube users should give next operating conditions that affect the life negatively their careful considerations.
