3Operating the Power Supply Locally

Press the OUT ON button to turn the output on.

Turn the AC power off, wait a few seconds, and turn it on.

Turn the output off, then on again using the Shut Off pin on the J1 connector. This only applies in Auto-Restart mode.

If the OVP continues to trip, try lowering the output voltage below the OVP setting, or raising the OVP setting.

Under-Voltage Limit

Under-voltage limit is a protection function that prevents adjustment of the output voltage below a set limit either from the front panel or remote interface. It does NOT include protection trip circuitry like the over-voltage protection. The combination of UVL and OVP lets you create a protection window for sensitive load circuitry.

Setting the UVL can be made when the output is enabled (On) or disabled (Off). To set the UVL level, press the OVP/UVL button twice, so that the display shows UUL. The display will show the UVL setting. Rotate the voltage knob to adjust the UVL level. The display will show UUL and the setting value for another five seconds and then return to its previous state.

The UVL settings are limited at the maximum level to approximately 5% below the output voltage setting. Attempting to adjust the UVL above this limit will result in no response to the adjustment attempt. The minimum UVL setting is zero.

Over-Current Protection

Over-current protection will shut down the power supply output if the load current exceeds the current limit setting. This protection is useful when the load is sensitive to an over-current condition.

To arm the over-current protection, press the OCP/488 button so that the OCP indicator illuminates. When armed, a transition from constant voltage to constant current mode will activate the over- current protection. When an over-current protection event occurs, the output is disabled, the display shows OCP, the PROT indicator blinks, and OC is set in the Questionable Condition status register.

Use one of the following methods to reset over-current protection after it activates. If the load current is still higher than the current limit setting, the over-current protection will be activated again.

Press the OUT ON button to turn the output on.

Turn the AC power off, wait a few seconds, and turn it on.

Turn the output off, then on again using the Shut Off pin on the J1 connector. This only applies in Auto-Restart mode.

Press the OCP/488 button to cancel over-current protection. The display will show OFF because OCP protection is latched. Press the OUT ON button to reset OCP. With this method, the over- current protection is disabled. If the load current is still higher than the current limit setting, the power supply will only attempt to limit the current at the current limit setting.
