WNC-3
Voltage indicator
with display, 3-phase
WNC-3 voltage indicator is designed to measure and indicate the
value of 3-phase AC voltage in the range of 80÷500 V AC.
The WNC-3 indicator contains three independent measurement
chains. The measured voltage values are indicated directly in
numerical form on the 3-row, 3-digit LED display. Voltages are
displayed with a resolution of 1 V, measurement is updated five
times per second.
The measured voltage is also used to power the indica-
tor. If the voltage drops below 80 V, the indicator display
may turn off.
