Feature:1. Varied Frequency Driver: Supports 1PH AC 220V input and 3PH AC 0-220V output, the 2.2KW variable frequency drive adopts IGBT module for good bearing capacity and more stability.2. Over Voltage Protection: When the bus voltage gets up to or exceeds the bus overvoltage suppression point during the operation, the frequency converter will automatically adjust the operating frequency to suppress the bus voltage rise, thereby ensuring that the frequency converter does not activate overvoltage protection due to excessive bus voltage.3. Over Current Protection: During operation, through real time monitoring of the load current, the VFD 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. Broad Range Application: 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.5. Comes with Great Design: Independent air duct design along with industrial flame retardant ABS material enables high impact resistance, high heat resistance, high safety and reliability.Specification:Item Type: Variable Frequency DriveMaterial: Flame retardant ABS.
