The WNC-3 three-phase voltage indicator consists of three independent measurement paths. The measured voltage values are directly displayed in numeric form on a 3-row, 3-digit LED screen. Voltages are displayed with a resolution of 1 V and the measurement is updated five times per second. The measured voltage is simultaneously used to power the indicator. In case of low voltage below 80 V, the indicator's display may turn off.
