l-n
,
direct-coupled.
TRANSFORMER
RATIO
The Transformer Ratio Setting of the UPC is always set to 0.0 in these models. (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 these models. (Refer to the

3.2.3 OUTPUT VOLTAGE RANGE CONFIGURATION, MODEL 315-ASX
This paragraph describes the configuration of the Output Voltage Range for the Model 315-ASX
Power Source. This model can be configured for either 0-132 VAC
l-n
, 0-198 VAC
l-n
, 0-264 VAC
l-n
,
or 0-330 VAC
l-n
. The 0-198 VAC range is designated as the VR1.5 output form, the 0-264 VAC
range is defined to be the VR2.0 output form, and the 0-330 VAC range is defined as the VR2.5
output form. An Output Transformer Assembly is required for the 198, 264, and 330 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 3.2.3 for voltage range tap selection information.
TRANSFORMER
RATIO
When the system is supplied with the VR1.5 output form, set the Transformer Ratio Setting of the
UPC-3 to 1.5. (Refer to the UPC-Series Operation Manual for details.) The Transformer Ratio
setting is set to 2.0 for systems configured with the VR2.0 output form and 2.5 for systems
configured for the VR2.5 output form. The Transformer Ratio setting is set to 0.0 on systems not
equipped with output transformers.
AMPS TO VOLTS RATIO
The Amps to Volts Ratio Setting of the UPC-3 is always set to 6 for the Model 315-ASX. (Refer to
the UPC-Series Operation Manual for details.)
