3.2.5 OUTPUT VOLTAGE RANGE CONFIGURATION, MODEL 312-AMX
The Output Voltage Range for the Model 312-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 312-AMX. (Refer
to the
UPC-Series Operation Manual
for details.)
3.2.6 OUTPUT VOLTAGE RANGE CONFIGURATION, MODELS 140-AMXT,
160-AMXT, 320-AMXT, 345-AMXT, 360-AMXT, 390-AMXT and 3120-AMXT
The Output Voltage Range for the Models 140, 160, 320, 345, 360, 390, and 3120-AMXT
Power Sources can be configured for either 0-135 VAC
l-n
, 0-204 VAC
l-n
defined as the VR1.5
output form, 0-273 VAC
l-n
defined as the VR2.0 output form or 0-341 VAC
l-n
defined as the
VR2.5 output form. A Magnetics Module (Assembly No. 134350) is required for the VR1.5,
VR2.0, and VR2.5 output forms.
Refer to Figure 3.2.7 for location of components referenced below and range tap selection
information.
Conversion to the VR (X.X) output form is as follows:
1)
Remove the top cover of the Magnetics Module.
2) Wire for (X.X):1 ratio as per wire table of Figure 3.2.7.
3) Replace top cover of Magnetics Module.
4) Connect Magnetics Module to the power source. The Magnetics Module is
connected to the power source by attaching P20 of the Magnetics Module to J20 of
the power source. Also be sure to connect the Chassis GND wire of the Magnetics
Module to the CHS GND stud on the rear panel of the power source.
5) Set the Transformer Ratio Setting of the UPC. (Refer to the
UPC-Series Operation
Manual
for details.)
6) Set the Amps to Volts Ratio Setting of the UPC (Refer to the
UPC-Series Operation
Manual
for details.)
7) Calibrate the power source as stated in Section 6 of this manual.
