FAQ: How are the over-current and over-voltage protection functions implemented in the N6700 series?

Overvoltage is a hardware feature and monitors the output terminals (+/-, not at the sense terminals). This will trip within about 100 microseconds of detecting an overvoltage condition.

Overcurrent protection works by detecting when the unit goes into CC mode, not by actually measuring the output current. This means that the shutdown time varies, depending on how large the over-current is.
