Setting Foldback Mode
Foldback mode is used to disable the output when a transition is made between the operating modes. The power supply will turn off/disable the output and lock in foldback mode after a specified delay if the power supply transitions into CV mode or into CC mode, depending on the foldback mode settings. This feature is particularly useful for protecting current or voltage sensitive loads. Foldback can be set to trigger a switch when transitioning from CV to CC mode or from CC to CV mode.
To set the foldback protection and foldback delay time:
1. Turn the

3.Press the rotary Adjust/Enter control when the desired mode has been selected.
The FLD LED will illuminate and DELA will be displayed in the output voltage display.
4.Adjust the desired delay time using the rotary Adjust/Enter control.
The range can be set from 0.50 seconds to a maximum of 50 seconds. The step size is in increments of 0.05 seconds when setting from 0.50 to 5 seconds and then in 1 second increments from 5 seconds to 50 seconds.
5.Once the desired foldback delay time has been selected, press the rotary Adjust/Enter control to commit the foldback delay setting.
To disable foldback protection:
