Knowledge points Where to use MX321 AVR? The MX321 AVR (Automatic Voltage Regulator) is commonly used in applications where precise voltage regulation is required for synchronous alternators or generators. Here's a brief description: The MX321 AVR is utilized in various industrial, commercial, and residential settings that rely on synchronous alternators or generators. This includes applications such as backup power systems, industrial power plants, construction sites, data centers, and telecommunications facilities. The primary function of the MX321 AVR is to regulate and stabilize the output voltage of the alternator or generator, ensuring it remains within a specific range regardless of fluctuations in the load or input conditions. This helps maintain a steady and reliable power supply, preventing voltage surges or drops that could damage connected equipment. The MX321 AVR incorporates advanced control algorithms and sensing mechanisms to monitor voltage variations and adjust the excitation current supplied to the alternator's field windings accordingly. This allows for precise voltage regulation and enhances the overall stability and performance of the electrical system. The MX321 AVR is designed to be compatible with a wide range of generators and can be integrated into different control systems to provide accurate voltage regulation for optimal operation.   MX321 Details Part Number:MX321 Part Type:AVR MOQ:10pcs Voltage sensing:190-264 VAC, 2 or 3 phase Frequency:50 or 60 hz Field Output:120 VDC max, 2.7 A Voltage Regulation: +/- .5 PMG Excited   MX321 Picture show
