Specification Item Type: Variable Frequency Drive Material: Flame Retardant ABS Model: SKI90-7D5G/011P-4 Input: 3PH AC380V±15% 20.5A 50-60Hz Output: 3PH AC0-380V 17.0A 0-400Hz Power Capacity: 11KVA Suitable Motor: 7.5KW 10HP 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. Overcurrent Suppression Protection: During operation, through real time monitoring of the load current, it 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.
