To protect voltage sensitive loads, the Z+ series of programmable power supplies have user adjustable set points for the over-voltage protection (OVP), the under-voltage level (UVL) and the under-voltage protection (UVP).

This is achieved through the use of the menu button and the voltage and current encoders. This changes the default setting of +10% for the OVP. The under-voltage level can be set to prevent the output voltage going lower than a level that is desired.  If the load increases and the voltage drops, then the Z+ will remain in constant current limiting. If the undervoltage protection (UVP) is activated then the output will be disabled once the limit is reached.
