SECTION 4 OPERATION
4.6.3.5 RANGE CONTROL
Some power source models support Range Control to achieve maximum efficiency by matching the
internal power supply to the output voltage requirement. The UPC allows selection of Range Control
parameters even when it is not supported by the attached power source. In this case the following
screens have no effect. The RANGE CONTROL SETUP menu is accessed from the General Setup
menu (fn,3,5).
RANGE CONTROL MODE: MANUAL
SELECT OUTPUT RANGE: 1
RANGE CONTROL MODE:
SELECT OUTPUT RANGE:
NOTE: The above Output voltages are for Single phase operation. If split (2) phase operation is used,
the listed Output voltage ranges are doubled.
Press EXECUTE to save the parameter entries.
4.6.3.6 SLEW RATE SETUP
Selecting SLEW RATE SETUP from the General Setup menu (fn,3,6) allows the slewing functions to
transition at a predetermined rate
SLEW RATE SETUP:
VOLTS / SEC. = 1
HERTZ / SEC. = 1
Default values are 1 volt/second and 1 Hz/second.
Press EXECUTE to save the parameter entries.
NOTE: Slew rates are approximate.
AUTO, MANUAL. There are 2 modes of operation for Range Control:
AUTO and MANUAL. AUTO is the default mode. Pressing the +/- key
when the cursor is in the MODE field toggles between AUTO and
MANUAL MODE. When MANUAL MODE is selected, an OUTPUT
RANGE may be set.
