Page 100: Protection Functions
Protection Functions Protection Functions Overvoltage protection (OVP) In constant current mode, the U3606A regulates the output current at the selected value, while the voltage varies as required by the load. The overvoltage protection protects against overvoltage conditions on the output. If the load attempts to draw more voltage than required, such that it exceeds the programmed protection value, the overvoltage protection circuit will protect the load by disabling the output.
Page 101 Then very gradually increase the output current using the directional keys until the OVP circuit trips. This will disable the U3606A output, cause the CC annunciator to flash, and the OV and Error annunciator to illuminate.
