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.

1.Disconnect the power supply.
2.Install the indicator on the rail in the distribution board.
3.Connect the indicator to the source of measured voltage ac-
cording to the diagram.
It is recommended to protect each phase of the indica-
tor with a slow-blow fuses with a rating current of 0.25
or a 3-phase circuit breaker with B characteristics and
rating current of 1 A.
4.Switch on the power supply and verify that the device is wor-
king correctly.
