HEAT SINKING
The NuPower 12B01A is offered as a stand‐alone module or with a kit, which also includes a fan‐cooled
heatsink with an AC / DC adapter, and an interface cable.
Figure 3: The NuPower PA Kit offers “out‐of‐the‐box” operation for the user. The fan‐cooled heatsink
with an AC/DC adapter is shown with an example PA (NuPower 12B01A not shown).
Caution: The use of external heat‐sinking is required especially for those applications
requiring high duty cycle operation (e.g. continuous wave) or for extended on‐time testing.
Operation without a proper heat sink under these conditions will cause permanent damage
to the product and will void the product warranty.
The external heatsink thermal resistance requirements are:
<0.25
˚
C/W for operation up to 60
˚
C ambient
<0.7
˚
C/W for operation up to 40
˚
C ambient
