Voltage indicator WN-711 single-phase, range: 200÷250V, 1 module

Professional voltage control solution for single-phase installations

The WN-711 voltage indicator is a professional solution for continuous monitoring of electrical parameters in single-phase installations. The device provides immediate visual control of the network status via a line of 10 LEDs, eliminating the need for external measuring instruments.

Precise LED indication system with color coding

The measurement system is based on 10 LEDs arranged along a scale, where each LED represents a specific voltage value with a reading accuracy of 2.5V. The measurement range is 205÷245V, and the scale division is 5V.

Color LED coding enables quick interpretation of the network status: green LEDs signal correct voltage within the tolerance range (215V to 245V), while red LEDs warn of deviations from the norm. The illumination of two adjacent LEDs means that the current voltage value is the arithmetic mean of their marked values.

Compact modular design and economical power supply

The device occupies one 18mm wide module, allowing for mounting on a standard 35mm DIN rail without taking up excessive space in the distribution board. The modular design allows for easy installation and subsequent expansion of the installation.

Power is drawn directly from the measured circuit (230V AC/DC), eliminating the need for additional power sources or batteries. Power consumption is a maximum of 0.8W, making the device economically viable even during long-term continuous operation.

Operating parameters and operating conditions

The device maintains full functionality across a wide range of operating temperatures (-25°C to +50°C), enabling installation both inside and outside buildings, provided an appropriate distribution board enclosure is used.

Connection is made via 2.5mm² screw terminals with a tightening torque of 0.4Nm, ensuring a secure connection for wires of various cross-sections. The IP20 protection rating guarantees safe mounting inside electrical distribution boards.

The system can operate in two modes: single LED or LED bar ("bar"), switched by shorting or leaving terminals 10-12 open, providing flexibility to adapt the presentation of results to user preference or application specifics.
