Description
Actual output current display at normal operation. While
adjusting the output current, the set value will be shown.
The display will automatically return to show the actual
current approx. 3sec from completion of adjustment.
Actual output voltage display at normal operation. The
measurement circuits monitor the voltage at the sensing
points, hence at remote sensing where there is voltage
drop on the load wires, the voltage at the power supply
output terminals will be higher than the displayed value.
Attention should be taken not to exceed the output power
rating. While adjusting the output voltage, the set value will
be shown. The display will automatically return to show the
actual voltage approx. 3sec after completion of adjustment.
CV LED indicates that the power supply is regulating it's
output at a constant voltage.
CC LED indicates that the power supply is regulating it's
output at a constant current.
The ADJUST knob functions to determine the following
output parameters:
1. Output voltage adjust - as determined by V/A pushbutton
2. Output current adjust - as determined by V/A pushbutton
3. Over voltage protection adjust - as determined by
OVP/UVP pushbutton
4. Under voltage soft limit adjust-as determined
by OVP/UVP pushbutton
5. Address selection
ALM indicates alarm caused by activation of one of the
following protections:
* Over voltage protection
* Over temperature protection
* Foldback protection
Main function: Enable or disable the power supply output.
Auxiliary function: Press and hold OUT pushbutton for
approx. 3sec to change function to select between safe
mode restart and automatic restart.
Main function: Select between local or remote operation.
Auxiliary function: Press and hold REM pushbutton for
approx. 3sec to change function to select between RS232
or RS485 communication.
Pressing FOLD pushbutton arms foldback protection
which shuts down output if supply transits from CV to CC.
