External Power Supply Requirements
The external power supply used to power the loads must provide sufficient field
power for the module during short circuit events. When a load is shorted, an
inadequate external power supply may allow field power to drop below the
specified operating range, causing mis-operation of the module. The external
power supply must be capable of providing short circuit energy without
degradation of output voltage levels. The amount of energy required depends on
the number of simultaneously-shorted points that might occur. Refer to power
supply short circuit operation specifications when selecting the power supply to be
used with the loads.
Local energy storage (either batteries or capacitors) can be used to compensate
for insufficient power supply characteristics. Additional best practices including
minimizing wiring resistance from the external power supply to the module must
be observed.
