Output Voltage Range Configuration - Pacific AMX series Operation Manual

3.2

OUTPUT VOLTAGE RANGE CONFIGURATION

This paragraph describes the configuration of the Output Voltage Range for the AMX-Series Power Source.
The AMX-Series Power Source can be configured for several different Output Voltage Ranges. The standard
output configurations are:
1)
2)
3)
4)
The 0-110 through 0-150VAC output ranges are direct-coupled outputs and are always available. The
remaining output forms are transformer-coupled. Only one is available when output transformers are installed.
However, systems can be reconfigured for a different range, if required.
Configuration of the output voltage range is set at the time of order. Systems are configured at the factory as
ordered. The System ID label or Magnetics Module ID label will state the factory configured Voltage Range if
transformer-coupled outputs are present. If the output voltage range specified on the System ID label or
Magnetics Module ID label is that which is desired, no further action is required. Otherwise, reconfiguration is
required.
Also described in the following paragraphs are model specific controller details (Transformer Ratio and Amps
to Volts Ratio settings) that, although factory preset, must be set as described if inadvertantly changed or
otherwise modified.
Configuration of the Output voltage consists of
1) Verifying that the appropriate output transformer taps have been selected.
2) Verifying the proper setting of the Transformer Ratio Switch within the UPC.
3) Verifying the proper setting of the Amps to Volts Ratio Switch within the UPC
4) Calibration of the system.
Configuration varies from model to model. The following paragraphs describe the configuration settings of the
available standard output ranges. Refer to the appropriate paragraph for details. When custom output
transformers have been installed, refer to Section 9, Modifications. The instructions stated in Section 9 take
precedence over those listed in the following paragraphs.
