Protection Circuits
There are several protection circuits used in the amplifier. They are activated when one or more
parameters exceed defined values or some unwanted condition
occurs.
•
VSWR too high
•
Anode current too high
•
Anode voltage error
•
Screen current too high
•
Screen voltage error
•
Grid current too high
•
Grid voltage error
•
Heating voltage error
•
Mistuning of PA
•
Temperature too high
•
Soft start for fuse protection
•
“switch-on blocking “ at opened amplifier
