Three-phase voltage indicator WN-723, range: 3x200÷250V, 2 modules

Three-phase voltage indicator – precise measurement and control

WN-723 is a three-phase voltage indicator designed for continuous monitoring of voltage values in three-phase networks. The device finds application both in industrial installations and in public and residential buildings where constant control of power supply parameters is required. Mounting on a TH-35 rail facilitates integration with existing switchboards.

Key features and application

The WN-723 indicator offers a clear LED bar display that indicates the current voltage value in each phase. This makes it possible to quickly identify any power supply problems, such as voltage drops or increases. The device is particularly useful in situations where voltage stability is critical for the correct operation of connected devices and machines. Precise measurement (reading accuracy of 2.5V) allows for effective diagnostics and minimization of failure risk.

Construction and mounting

WN-723 has been designed with easy installation and intuitive operation in mind. The housing with dimensions of 2 modules (35mm) provides compact size, and mounting on a standard TH-35 rail is quick and easy. Screw terminals with a cross-section of 2.5mm² guarantee a secure connection of power supply cables. The device operates at a frequency of 50Hz and has a voltage measurement range of 200V to 250V per phase. Power supply control is performed using 11 LEDs. This means the user can quickly verify that the device is powered correctly.

Additional information for professionals

The WN-723 indicator does not have built-in configuration functions or analog or binary outputs. Its main task is to visualize the voltage value in a direct and understandable way. The device is characterized by high reliability and durability, making it an ideal choice for demanding industrial applications and building installations. It should be remembered about the operating temperature range of the device – optimal conditions ensure its long-term efficiency.
