Modular voltage indicator - 1 phase LCD WNC-1

Precise voltage measurement in your installation

The WNC-1 voltage indicator is a reliable device designed to measure and display AC voltage values in single-phase circuits. Its compact design, fitting into a single DIN rail module (18 mm wide), allows for easy mounting in electrical panels. This is an ideal solution for both professional installers and end-users who need precise monitoring of electrical parameters.

Functionality and application

The WNC-1 displays the measured voltage value on a clear, 3-digit LED display. The measurement range covers 80-500 V AC, making it a versatile tool for monitoring voltage in various applications – from home installations to industrial facilities. The device does not require an external power supply, as it uses the measured voltage for its own operation. However, it should be noted that if the voltage drops below 80V, the display may turn off.

Construction and mounting

The indicator is designed for mounting on a standard 35 mm DIN rail. Screw terminals with a cross-section of 1.5 mm² provide a secure and safe connection to the electrical installation. A tightening torque of 0.4 Nm guarantees connection stability. Accuracy class 1 ensures reliable measurement results. The device is characterized by a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm – it should be remembered to mount it in a dry and well-ventilated place. The digital measurement system ensures precision and stability of indications.
