HEAT SINKING
The NuPower 12D05A is offered as a stand‐alone module or with an accessory kit
(p/n NW‐PA‐ACC‐KT03), which includes a 28 VDC fan‐cooled heatsink and requisite power cable. [The kit
also includes an upgraded module interface cable assembly, labeled and terminated with banana plugs.]
Figure 3: The NuPower PA Kit offers “out‐of‐the‐box” operation for the user. The 28 VDC fan‐cooled
heatsink is shown with the NuPower 12D05A mounted.
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 maximum operating temperature is 85˚ C (baseplate).
