VDD is automatically controlled depending on temperature control and efficiency.
3.1.5. Temperature
You can read your current operating temperature here.
Fans are controlled automatically by the firmware.
Optimal operation is below 60 °C.
Above 60 °C firmware will begin decreasing power to protect the amplifier from permanent
damage.
If temperature exceeds 85° C the amplifier will go into alarm mode to prevent transmitting
before the temperature drops.
3.1.6. Power
The entire power bar range is from 0 to 2000W.
The red section is above 1500W.
3.1.7. SWR
Maximum allowed working SWR is 1:3.
Firmware will enable the power derating algorithm when SWR is between 1:1.5 and 1:3.
Above 1:3 SWR the amplifier will go to alarm mode, preventing transmitting.
