Feature: 1. WIDE APPLICATION: This frequency inverter is widely used in the speed regulation of various three phase asynchronous motors, achieving functions such as motor speed regulation, energy conservation and environmental protection, improving production processes, and improving production efficiency. 2. OVERVOLTAGE SUPPRESSION PROTECTION: When the bus voltage reaches or exceeds the bus overvoltage suppression point during the operation of the frequency converter, the frequency converter will automatically adjust the operating frequency to suppress the rise of the bus voltage, thereby ensuring that the frequency converter does not cause overvoltage protection due to excessive bus voltage. 3. OVERCURRENT SUPPRESSION PROTECTION: During operation, through real time monitoring of the load current, the frequency inverter automatically limits it to not exceed the set overcurrent suppression point to prevent fault tripping caused by excessive current. This function is particularly suitable for loads with large inertia or severe changes. 4. ALUMINUM ALLOY MATERIAL: Made of premium aluminum alloy, this frequency converter has a good heat dissipation, impact resistant and heat resistant, flame retardant, safe and reliable for long term use. IGBT module is adopted for stronger carrying capacity and better stability. 5. EASY OPERATION: Frequency inverter can realize the functions of one button constant pressure water supply macro, engraving machine macro, and machine macro, which is convenient to operate, efficient, and stable.
