THERMAL OPERATION
It is necessary that the base (heat sink surface - FIGURE 13) of
the PW-82520/21N be mounted to a heat sink. This heat sink
shall have the capacity to dissipate heat generated by the hybrid
at all levels of current output, up to the peak limit, while main-
taining the case temperature limit as per FIGURE 11.
BRUSH MOTOR OPERATION
The PW-82520/21N can also be used as a brush motor controller
for current or voltage control in an H-Bridge configuration.The PW-
82520/21N would be connected as shown in FIGURE 10.
All other connections are as shown in either FIGURES 6 or 7
depending on voltage or current mode operation.The Hall inputs
are wired per TABLE 4. A positive input command will result in
positive current to the motor out of Phase A.
OPTIONAL FEATURES
EXTERNAL SENSING RESISTOR
An external sense resistor can be connected to replace the inter-
nal resistor if this option is required. Please contact factory for
this option.
