Using Under Voltage Protection (UVP)
The UVP prevents voltage settings below a set value. The UVP lets you
create a voltage window of operation when used in conjunction with the
OVP setting. The UVP range is variable from 0 V to V
SET
–5%.
This feature is only available in APG mode. Furthermore, its not much of
a protection and does not have a latch and does not affect the output. Its
only a warning.
Defining the UVP Set Point
To define the UVP set point:
1. Turn the power supply On.
2. Set the output to the desired voltage.
3. Turn the mode control knob to the PRT position.
PRo OUP is displayed.
4. Turn the Rotary knob/Enter button until PRo UUP is displayed.
5. Press the Rotary knob/Enter button to select the UVP for setting up.
6. Set up the lower limit protection using the Rotary knob/Enter button.
7. Once the desired value has been set, press the Rotary knob/Enter
button to commit the setting.
See “Coarse and Fine Adjustment Modes” on page 3–2.

Over Current Protection (OCP)
The OCP alarm is a non-configurable alarm. The OCP triggers if the
output current exceeds 110% of the maximum model current. The
purpose of this alarm is to protect the power supply from damage should
an over-current situation occur.
