Usage Areas

Residential Electrical Protection: Protects household devices such as refrigerators, TVs, air conditioners, etc., from potential damage caused by voltage fluctuations. Ideal for both single-family homes and apartment buildings.
Commercial Spaces and Offices: Used in commercial premises to protect office electrical systems, where sensitive electronics may be impacted by voltage fluctuations. Ensures protection for computers, servers, and other sensitive devices against electrical disturbances.
Industrial Equipment: Suitable for small and medium-power industrial equipment where voltage fluctuations may pose risks. This protective relay module helps safeguard motors, compressors, and other equipment.
Pros

Automatic Protection from Voltage Fluctuations: The device automatically cuts off power during dangerous voltage fluctuations, protecting connected devices.
Adjustable Protection Limits: Allows the user to set overvoltage and undervoltage limits according to specific needs, providing optimal protection for different electrical systems.
Digital Display: The LED display shows real-time voltage, enabling users to monitor and control the electrical system and respond quickly to voltage fluctuations.
Compact and Easy to Install: The DIN rail mounting system enables quick and easy installation of the protection module into electrical distribution panels.
Versatile for Various Systems: The 63A single-phase load capacity is suitable for both residential and commercial environments, making it a universal and widely applicable solution.
Cons

Limited Protection Against Other Electrical Disturbances: This module only protects against voltage fluctuations and does not cover other issues such as frequency variations or harmonic distortions, which may be important for some users.
Single-Phase System Support Only: Designed only for single-phase systems, so it may not be suitable for three-phase systems or industrial equipment that requires additional protection.
Temperature Sensitivity in Extreme Environments: While operational between -25°C and +55°C, extreme high or low temperatures may reduce its efficiency or cause malfunctions if additional protective measures are not in place.
No Data Logging: The device lacks data storage or remote monitoring functions, so only the current voltage is visible in real-time, without historical data tracking.
The voltage protection relay module is an effective and reliable solution for protecting single-phase electrical systems from dangerous voltage fluctuations. With adjustable protection limits and a digital display, it allows easy monitoring and control of power supply, protecting sensitive equipment. This module is ideally suited for residential, office, or commercial use, though it may be less suitable for industrial or three-phase systems that require specialized solutions.
