3.2.4 OUTPUT VOLTAGE RANGE CONFIGURATION, MODELS 140-ASX, 160-ASX,
345-ASX, AND
360-ASX
This paragraph describes the configuration of the Output Voltage Range for the Models 140-ASX,
345-ASX, and 360-ASX Power Sources. These models can be configured for either 0-135 VAC
l-n
( 0-132 VAC
l-n
for Model 160/360-ASX), 0-203 VAC
l-n
(0-198 VAC
l-n
for Model 160/360-ASX)
defined as the VR1.5 output form, 0-270 VAC
l-n
(0-264 VAC
l-n
for Model 160/360-ASX) defined as
the VR2.0 output form, or 0-338 VAC
l-n
(0-330 VAC
l-n
for Model 160/360-ASX) defined as the
VR2.5 output form. A Magnetics Module (Assembly No. 134310) is required for the VR1.5, VR2.0,
and VR2.5 output forms.
Refer to Figure 3.2.4 for location of components referenced below and range tap selection
information.
Conversion to the VR1.5 output form is as follows:
1)
Remove the top cover of the Magnetics Module.
2)
Wire for 1.5:1 ratio as per wire table of Figure 3.2.4.
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 to 1.5. (Refer to the UPC-Series Operation
Manual for details.) The Transformer Ratio Setting is set to 0.0 on systems not equipped
with output transformers.
6)
Set the Amps to Volts Ratio Setting of the UPC to 12. (Refer to the UPC-Series Operation
Manual for details.)
7)
Calibrate the power source as stated in Section 6 of this manual.
Conversion to the VR2.0 output form proceeds as above, except that the Magnetics Module is
wired for the 2.0:1 ratio and the Transformer Ratio Setting of the UPC is set for 2.0.
Likewise, conversion to the VR2.5 output form proceeds as above, except that the Magnetics
Module is wired for the 2.5:1 ratio and the Transformer Ratio Setting of the UPC is set for 2.5.
The Transformer Ratio Setting of the UPC is set to 0.0 on systems without transformer-coupled
outputs.
While the above procedure can be performed in the field, Pacific Power Source recommends that
the system be returned to the factory when transformer-coupled outputs are to be added to the
system. This insures proper connection and calibration of the entire system.
