Suitable for use in underground coal mines with AC 50Hz and rated voltage of 660/1140V, specifically designed for driving permanent magnet synchronous electric drums. Power range: 55-250KW for 660V frequency converters, and 55-630KW (two-quadrant and four-quadrant) for 1140V frequency converters.
Utilizing internationally advanced vector control technology, this inverter boasts high speed regulation accuracy, fast dynamic response, and can output at least 2.2 times the rated torque, making it suitable for heavy-load starting applications.
The main and control circuits of the inverter employ imported components from renowned brands such as ABB, Siemens, and Infineon.
It features non-inductive laminated busbars, long-life film capacitors, and excellent electromagnetic design, effectively reducing input and output harmonics to meet EMC standards. Output cable lengths range from 0-1500 meters.
A 10.4-inch display provides user-friendly operation and displays a wealth of information.
A 16-key matrix keypad on the front door facilitates equipment debugging. The rational structural layout and modular design make it easy to maintain.
The inverter features overload, overvoltage, undervoltage, phase loss, overheating, power imbalance, short circuit, leakage current lockout, and over-temperature protection.
