HEAT SINKING
The NuPower 11B02A-TAC2 features an integrated heatsink. The chassis/integrated heatsink was
designed for short-duration transmit periods. If chassis temperature is allowed to exceed 85°C (default),
the Temp Fault line will go low (0VDC) and bias to internal amplifiers will be removed until cooled to
approximately 70°C.
Note: If desired, factory can reduce thermal shutdown point to protect users if worn on body. Contact
[email protected] to request changes.
