Output Power - Pacific Power Source AMX Series Operation Manual

2.1.2 OUTPUT POWER

OUTPUT VOLTAGE RANGE
DIRECT-COUPLED
The standard output voltage range for most of the AMX-Series Power Source is 0-135 VAC
when operated in the direct-coupled mode. Additionally, the Models 112-AMX, 125-AMX and
312-AMX can operate from 0 to 150 VAC
nominal input voltage applied.
TRANSFORMER-COUPLED
The output voltage range of the AMXT-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.
TURNS RATIO
1.5:1
2.0:1
2.5:1
NOTE: Models 112-AMX, 125-AMX and 312-AMX require special consideration for

FULL-RATED CURRENT
The full-rated output current of the AMX-Series Power Source is listed below by model
number. Current is stated for output voltage set to 125 VAC
Rating chart, Figure 2.1.2(A-N), for 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.
