FAQ: What are the OVP characteristics of the N6900 and N7900 series?

The N6900 and N7900A APS series support OVP protection based on sense lead voltage, with an additional backup OVP protection at the output terminals.

The backup local OVP function tracks the programmed OVP setting and trips if the voltage at the + and – output terminals rises more than 1V + 10% of the unit's voltage rating above the programmed OVP setting.

The response time of the OVP is typically <30 us from the occurrence of the over-voltage to the start of the shutdown.
