3.2.6 OUTPUT VOLTAGE RANGE CONFIGURATION, MODELS 140-AMXT,
160-AMXT, 320-AMXT, 345-AMXT, 360-AMXT, 390-AMXT and
3120-AMXT (cont.)
TRANSFORMER RATIO
Conversion to the VR1.5 output form, the Magnetics Module is wired for the 1.5:1 ratio and the
Transformer Ratio Setting of the UPC is set for 1.5.
Conversion to the VR2.0 output form, the Magnetics Module is wired for the 2.0:1 ratio and the
Transformer Ratio Setting of the UPC is set for 2.0.
Conversion to the VR2.5 output form, 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.
AMPS TO VOLTS RATIO
The Amps to Volts Ratio Setting of the UPC is always set to 15 for the Models 140-AMX,
160-AMX, 345-AMX, and 360-AMX. (Refer to the UPC-Series Operation Manual for details.)
The Amps to Volts Ratio Setting of the UPC is always set to 30 for the Models 390-AMX and
3120-AMX. (Refer to the UPC-Series Operation Manual for details.)
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.
