The device provides operation control and protection of the power amplifier.

Main functions:

  • Displaying the output power value, SWR value and PA current consumption value;
  • Temperature monitoring and smart fan control using PWM;
  • Built-in digital sequencer with bypass modes support;
  • Sound and led alarm;
  • Protection on overheating and SWR value exceeding;
  • Calibration of the built-in SWR meter using only a power meter;
