2.1.2 OUTPUT POWER

OUTPUT VOLTAGE RANGE
DIRECT-COUPLED
The standard output voltage range of the AMX-Series Power Source is 0-135 VAC
Model 125-AMX) when operated in the direct-coupled mode. Additionally, the Models 112-AMX and 312-
AMX can be configured for several direct-coupled output voltage ranges between and including 0-110 VAC
and 0-150 VAC

TRANSFORMER-COUPLED
The output voltage range of the AMX-Series Power Source varies when operated in the transformer-coupled
mode. Maximum output voltage is determined by the transformer turns ratio. See list below for maximum
output voltage vs. turns ratio.

OUTPUT CURRENT
FULL-RATED CURRENT
The full-rated output current the AMX-Series Power Source is listed below by model number. Current stated
for output voltage set to 125 VAC
maximum current at reduced voltage. Output current ratings are scaled appropriately when using transformer-
coupled outputs.

OVERLOAD OPERATION
The AMX-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.
. These voltages are stated for full rated load and nominal input voltage applied.
