Feature: 1. Overvoltage Suppression: When the bus voltage reaches or exceeds the overvoltage suppression point during the operation of the frequency inverter, the inverter will automatically adjust the operating frequency to suppress the bus voltage increase. To ensure that the frequency converter does not cause overvoltage protection due to high voltage of the bus. 2. IGBT Module: The frequency inverter adopts integrated IGBT module, with great load carrying capacity and better stability, independent air duct design, superior stability performance. 3. Overcurrent Suppression: Variable frequency drive automatically limit the load current from exceeding the set overcurrent suppression point through realtime monitoring of the load current during operation to prevent fault tripping caused by excessive current. Suitable for loads that vary dramatically. 4. Double Rows Digital Tube Display: The inverter is a double rows digital tube display, is widely used for speed regulation of various 3 phase asynchronous motors to realize the functions of motor speed regulation, energy saving and environmental protection, and improving production efficiency. 5. ABS Housing: Variable frequency drive is with low frequency and large torsion, high impact and high heat resistance in ABS housing, and strong flame retardancy.
