Protection Function Activation

Setting limitation functions

You can use the CONFIG settings to apply limits to the voltage and current output settings. You can set limitations so that the programmed values cannot exceed the set overvoltage protection (OVP trip point) and the set overcurrent protection (OCP trip point) and so that the values cannot be lower than the set undervoltage limit (UVL trip point).

By using this feature, you can avoid accidentally turning the output off by mistakenly setting the voltage or current to a value that exceeds the set OVP or OCP or to a value that is lower than the set UVL.

If you have selected to limit the voltage setting (CF15: on), the valid programmable voltage values will be limited to voltages that are less than 95% of the OVP trip point and voltages that are greater than the UVL trip point. In addition, you will no longer be able to set the OVP trip point to a value that is lower than the set output voltage or the UVL trip point to a value that exceeds the set output voltage.

If you have selected to limit the current setting (CF14: on), the valid programmable current values will be limited to currents that are less than 95% of the OCP trip point. In addition, you will no longer be able to set the OCP trip point to a value that is lower than the set output current.
