... In the interest of product improvement, specifications are subject to change without notice. Q Overvoltage Detection When Only One Phase Exceeds the Overvoltage Threshold The K8AB-PM@ monitors each of the three-phase voltages. This means an overvoltage is detected if even only one phase exceeds the threshold value. The same applies to undervoltages. ...
