Overload Operation
The LMX-Series Power Source will deliver up to 150% of rated rms output current into unity
power factor loads at full-rated output voltage. Low output power factor, reduced output
voltage, and elevated ambient temperatures will increase the internal dissipation of the
power source and can cause overload shutdown due to over-temperature conditions.
Length of time to reach over-temperature varies with the models and the above parameters
