3.2.2 OUTPUT VOLTAGE RANGE CONFIGURATION, MODEL 112-AMX
The Output Voltage Range for the Model 112-AMX Power Source can be configured for either
0-110 VAC
l-n
, 0-125 VAC
l-n
, 0-135 VAC
l-n
, or 0-150 VAC
l-n
. All ranges are direct-coupled
outputs and are provided to maximize output current for a given output voltage. The output
form of a system is configured differently, depending on which controller a system is equipped
with, (Refer to the
UPC-Series Operation Manual
for details.)
TRANSFORMER RATIO
The Transformer Ratio Setting of the UPC is always set to 0.0 in this model. (Refer to the
UPC-Series Operation Manual
for details.)
AMPS TO VOLTS RATIO
The Amps to Volts Ratio Setting of the UPC is always set to 6 in the Model 112-AMX. (Refer
to the
UPC-Series Operation Manual
for details.)
3.2.3 OUTPUT VOLTAGE RANGE CONFIGURATION, MODEL 125-AMX
This paragraph describes the configuration of the Output Voltage Range for the Model
125-AMX Power Source. This model is configured with a 0-150 VAC
l-n
range. This range is
a direct-coupled output.
TRANSFORMER RATIO
The Transformer Ratio Setting of the UPC is always set to 0.0 in this model. (Refer to the
UPC-Series Operation Manual
for details.)
AMPS TO VOLTS RATIO
The Amps to Volts Ratio Setting of the UPC is always set to 9 in the Model 125-AMX. (Refer
to the
UPC-Series Operation Manual
for details.)
3.2.4 OUTPUT VOLTAGE RANGE CONFIGURATION, MODELS 305-AMXT and
308-AMXT
The Output Voltage Range for the Models 305-AMXT and 308-AMXT Power Sources can be
configured for either 0-135 VAC
l-n
, 0-204 VAC
l-n
, 0-273 VAC
l-n
, or 0-341 VAC
l-n
. The 0-204
VAC range is designated as the VR1.5 output form and the 0-273 VAC range is defined to be
the VR2.0 output form. An Output Transformer Assembly is required for the 204, 273 and
341 VAC output forms. Installation of the VR1.5, VR2.0 or VR2.5 output forms is performed
by the factory and can be installed on existing units not so equipped. Refer to Figure 3.2.4
for voltage range tap selection information.
TRANSFORMER RATIO (Refer to the
UPC-Series Operation Manual
for details.)
The Transformer Ratio Setting is set to 1.5 for systems configured with the VR1.5 output form.
The Transformer Ratio Setting is set to 2.0 for systems configured with the VR2.0 output form.
The Transformer Ratio Setting is set to 2.5 for systems configured with the VR2.5 output form.
The Transformer Ratio Setting is set to 0.0 for systems configured with the VR0.0 output form.
AMPS TO VOLTS RATIO
The Amps to Volts Ratio Setting of the UPC is always set to 6 in the Models 305-AMX and
308-AMX. (Refer to the
UPC-Series Operation Manual
for details.)
