Local Operation

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 9-position mode control to the PRT position. PRo OUP is displayed.

4.Turn the rotary Adjust/Enter control until PRo UUP is displayed.

5.Press the rotary Adjust/Enter control to select the UVP for setting up.

6.Set up the lower limit protection using the rotary Adjust/Enter control.

See “Coarse and Fine Adjustment Modes” on page 3–3.

The SCPI command (s) for these instructions are:

Over Current Protection (OCP)

The OCP alarm is a firmware alarm that is only configurable using the SCPI interface. The OCP triggers if the output current exceeds the OCP set point. Because the OCP alarm is a firmware based alarm it has a latency before detection of the condition can occur. The user should be aware of this latency and take this into consideration when relying on OCP to protect a sensitive load. The maximum period for detecting an OCP condition is 300 ms.

OCP is fixed at 110% of rated current.
