3.7 Output Voltage Ranges
The standard 2001RP AC power source has two output voltage ranges 0-150 V
AC
and 0-300
V
AC
. The operator may switch from one range to the other at will with no special precautions
except to remember that the output voltage will go to zero voltage whenever a range change
takes place.
Certain options available on the 2001RP series may result in different voltage range values
or a single voltage range only. Certain models like the 2001RP-AV may be ordered with a
single voltage range only. On single voltage range units, the Range change button has no
function and the LED indicator is not used. The following 2001RP versions are available:

2001RP 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 150 or below 146 V
RMS
. (For standard 2001RP, changeover points differ for
different voltage range pairs.)
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 output temporarily goes 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.

2001RP-AV units can be factory configured for single voltage range. In this case, the high voltage range is
not present.
