HEAT SINKING
The NuPower NW-PA-S-10-C01-S01 is offered as a stand-alone module or with an optional heat sink
(P/N: HTSK-08), which includes a 28 VDC fan-cooled heatsink and requisite power 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 NW-PA-S-10-C01-S01 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
˚
