WNC-3 three-phase voltage indicator WNC-3

WNC-3 three-phase voltage indicator from the manufacturer F&F. The product catalog number is WNC-3. It is used to measure and indicate the value of 3-phase alternating voltage in the range of 80÷500 V AC. The WNC-3 indicator consists of three independent measurement paths. The measured voltage values are indicated directly in numerical form on a 3-row, 3-digit LED display. Voltages are displayed with a resolution of 1 V, the measurement is updated five times per second. The measured voltage is also used to power the indicator. If the voltage drops below 80V, the indicator display may turn off.
