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.
