Output Voltage Ranges - Ametek 2003RP User And Programming Manual

3.7 Output Voltage Ranges

The standard 2003RP AC power source has two output voltage ranges 0-135 V
V . The operator may switch from one range to the other with no special precautions
AC
except to remember that the output voltage will go to zero whenever a range change takes
place.
Certain options available on the 2003RP series may result in different voltage range values
or a single voltage range only. Certain models like the 2003RP-AV may be ordered with a
single voltage range only. On single voltage range units, the range change button has no
function and the High Range LED indicator is never illuminated. The following 2003RP
versions are available:

2003RP AC power source models with dual voltage ranges offer an auto voltage range
change mode. In this mode, the voltage range is automatically changed when the user sets
a voltage above 135 V
below 150 V
RMS
The AUTO mode can be selected by pressing the range change button until the AUTO mode
LED illuminates. To take the AC power source out of the AUTO voltage range mode, press
the Voltage range button briefly. This will put the unit in the present range but takes it out of
auto mode.
Note: Even in AUTO mode, the three outputs temporarily go to zero volts when
a voltage range change occurs. If this is not acceptable, the AC source
should be operated in the high voltage range only and not in AUTO mode.

2003RP-AV units can be factory configured for single voltage range. In this case, the high voltage range is
not present.
