Acceptable Size and Duration of Power Line Voltage Fluctuations
The Motor Control Module is designed to withstand volt
age fluctuations from the incoming power supply. If the
incoming power supply goes outside of the tolerable
range, an over-voltage condition is flagged and the sys
tem shuts down in an alarm state. Excessive or
repeated over-voltage may permanently damage hard
ware. The chart below shows the permissible magnitude
and duration of temporary over-voltage events. Consult
a qualified electrician if there are any concerns about
the available power supply.
