THERMAL OPERATION
It is recommended that the base of the PWR-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 out-
put, up to the peak limit, while maintaining the case temperature
limit as per FIGURE 11.
BRUSH MOTOR OPERATION
The PWR-82520/21N can also be used as a brush motor controller
for current or voltage control in an H-Bridge configuration. The
PWR-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
The external sensing points are available for the end users to
install an external resistor (non-inductive). The resistance of the
resistor is scaled to the applicable current range. Please contact
factory for this option.
