Product Introduction

220V 60Hz 3 Phase AC Voltage Stabilizer (automatic voltage regulators) Solving voltage fluctuations Compatible with 200V 208V 240V.The product are generally used in Brazil,  Venezuela and  Philippine, where the local power supply follows the unique specifications of three-phase 200V/208V/220V/240V, 60Hz, which are significantly different from the common international standards. In these areas, electrical equipment is highly prone to operating failures or even damage due to unstable voltage. In order to effectively solve the problem of voltage fluctuations and based on the consideration of the demand for reliable power voltage stabilization in these areas, we have carefully developed and produced advanced industrial voltage regulation, also known as automatic voltage regulators. Therefore, the AVR for 60Hz grids is tailored for the local power grid and has a fast – response voltage stabilization mechanism that can instantly stabilize the fluctuating voltage within the standard range, providing stable and reliable power protection for various electrical equipment, greatly reducing equipment losses and extending equipment life.

Voltage stabilization characteristics

• High-precision voltage regulation: The output voltage of 3-phase 220V 60Hz voltage stabilizers can be stabilized at three-phase 220V, and the voltage regulation accuracy can usually reach ±1% to ±3%.
• Fast response: 3-phase 220V 60Hz voltage stabilizers can respond to voltage fluctuations in a very short time, and the general response time is 0.08s to 1s.
• Wide input voltage range: It can adapt to a wider input voltage range, generally in the range of 150V-290V or wider.
• High efficiency: The conversion efficiency is usually above 95% to 98%.
• Low waveform distortion: 3-phase 220V 60Hz voltage stabilizers will not cause obvious distortion to the input AC voltage waveform, and the waveform distortion rate is generally less than 0.01%.
• High reliability: AVR uses high-silicon silicon steel sheets, high-temperature resistant enameled wires, and high-temperature insulating paper. High-quality materials ensure safe and reliable operation in different environments.
• Automatic adjustment: It uses an intelligent control system to automatically adjust the output voltage according to changes in input voltage and load without manual intervention.
• Remote monitoring function: Some high-end three-phase 220V 60Hz voltage stabilizers support remote monitoring and management functions. Users can monitor the operating status of the voltage stabilizer anytime and anywhere through mobile phones, computers and other devices.
• Easy maintenance: The structural design is reasonable and the internal layout is compact, which is easy to install and maintain.

The figure above explains in detail the workflow and functional modules of the 3-phase 220V 60Hz voltage stabilizers (automatic voltage regulator) from grid input to stable output.
The high-speed microcontroller based on the ARM Cortex M4 core collects the input and output voltages, and compares and calculates with the set output voltage. The servo motor adjusts the turns ratio of the autocoupler voltage regulator to accurately control the output voltage. It has LCD display, 485 communication and various protection functions.

Advanced protection features

• Overvoltage Protection (OV): When the output voltage of 3-phase 220V/60Hz voltage stabilizers  exceeds the set overvoltage threshold, the power supply will be quickly cut off or voltage reduction measures will be taken, such as when it exceeds the rated voltage by 10%.

• Undervoltage Protection (UV): When the output voltage is lower than the set undervoltage threshold, such as lower than the rated voltage by 15%, the voltage regulator will take protective action.

• Overload Protection (OC): When the load current exceeds the rated capacity of the voltage regulator, the overload protection mechanism will be activated (it can be bypassed or set to cut off the output).

• Short – circuit protection: When a short – circuit fault occurs at the output end, the circuit can be instantly cut off to prevent the short – circuit current from damaging the equipment and lines.

• Lightning protection: Some 3-phase 220V/60Hz voltage stabilizers are equipped with lightning protection modules, which can effectively suppress the damage to the equipment caused by lightning overvoltage.

• Phase – loss and reverse phase detection protection: 3-phase 220V/60Hz voltage stabilizers can monitor the three – phase input and output voltages in real – time. Once the fault is detected, rapidly take protection action to prevent the motor and other equipment from being damaged due to phase – loss operation.
