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
misoperation 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.
