Usage

Electrical Distribution Boards: This device is ideal for installation in electrical distribution boards, where it can automatically disconnect the power if the voltage fluctuates beyond safe limits.
Residential and Commercial Premises: Suitable for use in residential and commercial spaces to protect sensitive devices, such as refrigerators, televisions, computers, and other electronics, which are vulnerable to voltage fluctuations.
Industrial Environment: Can be used in industrial facilities to ensure a stable power supply to equipment sensitive to voltage fluctuations.
Pros

High-Level Protection: This device automatically protects connected equipment from hazardous voltage fluctuations by disconnecting the power in case of overvoltage or undervoltage.
Adjustable Voltage Limits: The device allows for setting custom protection limits, which can be easily adapted to individual needs.
Easy DIN Rail Mounting: DIN rail installation provides quick and convenient setup in electrical distribution boards.
High Rated Current (63A): Suitable for a wide range of systems, including residential, commercial, and some industrial applications.
Safety and Reliability: The digital protection system ensures accurate voltage monitoring and quick response to fluctuations, enhancing the safety of connected equipment.
Cons

Limited Phases: As a single-phase device, it is not designed for three-phase systems, where more comprehensive voltage control is required.
High Voltage Limits May Not Suit All Residential Systems: Although the overvoltage limit is set to 270V, this may be too high for certain sensitive residential systems.
Voltage Protection Only: The device provides protection against overvoltage and undervoltage but lacks protection from other electrical issues, such as frequency instability or power surges.
Dependence on Network Stability: The device’s performance depends on the stability of the electrical network; in suboptimal or poor-quality installations, unexpected activations of the protection function may occur.
This overvoltage and undervoltage protection device is an ideal choice for both residential and commercial environments where sensitive equipment needs protection from dangerous voltage fluctuations. It is easy to install, reliable, and offers adjustable protection limits, though it is not suitable for three-phase systems. This device provides an excellent solution to ensure the safety of electrical equipment from voltage variations.
