Thermal Interlocks
The AOM and Driver are fitted with thermostatic switches which will switch open circuit if a
predetermined temperature is exceeded. These thermal interlocks will reset once the AO device and /
or RF driver are cooled below this temperature.
- The driver thermal switch over-temperature threshold is 50deg C
- The AOM740-H series thermal switch over-temperature threshold is 32deg C
The hysterisis of the thermal switches is 7-10deg C.
Once in a fault state the coolant temperature may need to be reduced to reset the thermal switches.
Precautions
TTL digital input levels must not exceed 7 volts
PLC logic input levels must not exceed 24 volts
Water cooling is mandatory.
The heatsink temperature must not exceed 70
°
C.
Corrosion inhibitor should be added to the cooling water
SERIOUS DAMAGE TO THE AMPLIFIER MAY RESULT IF THE TEMPERATURE EXCEEDS 70
°
C.
SERIOUS DAMAGE TO THE AMPLIFIER MAY ALSO RESULT IF THE RF OUTPUT CONNECTOR
IS OPERATED OPEN-CIRCUITED OR SHORT-CIRCUITED.
