1VR1 (Single-phase Voltage Regulators) is a type of power line filter modules used to reduce or control voltage fluctuations in the electrical system. The 1VR1 module provides an economical and effective solution to help maintain voltage levels and reduce harmonics in medium or large-scale industrial applications.

1VR1 modules are designed to help protect electrical equipment from power surges, thermal overload, undervoltage, and other disturbances. They provide cost-effective protection while generating accurate, reliable, and optimized performance. As a result, they are widely used in industrial applications, particularly in the field of automation, such as HVAC systems, process control, and instrumentation.

The 1VR1 module works based on a simple principle, which is voltage regulation. The module regulates the input voltage by using a transformer with a wound second winding. As the voltage increases, the transformer reacts, raising the load current in the secondary winding and thus reducing the output voltage of the module. Conversely, when the input voltage decreases, the transformer reduces the load current in the secondary winding, thus raising the output voltage of the module. By this regulation, the module can efficiently control the output voltage and provide reliable protection from overvoltage and undervoltage conditions.

The major components of 1VR1 power line filter modules include the transformer, the rectifier and the filter. The transformer is the important component of the module, which helps to maintain the voltage levels in the electrical system. The rectifier converts the alternating current (AC) of the input voltage into direct current (DC) and the filter smoothens the DC output. The rectifier is connected between the transformer and the filter, and it converts the AC power into the desired DC power. Finally, the filter regulates and smoothens the output voltage to provide a steady voltage to the connected devices.

In conclusion, 1VR1 power line filter modules are an effective and economical way to reduce voltage fluctuations in the electrical system. By using a transformer, rectifier, and filter, the modules are able to accurately regulate the input current and output voltage, providing optimal protection from power surges, thermal overload, and undervoltage. With their reliable performance and cost-effective protection, 1VR1 power line filter modules are favoured in the automation and instrumentation industries, and can be installed in any electrical system.
