1、SPECIFICATIONS: The input voltage is 1PH AC220V, the output voltage is 3PH AC0-220V, used for 1.5KW 2HP motors to achieve motor speed regulation function. 2、HEAT DISSIPATION: The frequency converter adopts independent air duct design to quickly export heat to achieve cooling effect and prevent the machine from overheating. 3、ABS HOUSING: The inverter housing is made of ABS plastic, which is heat resistant, impact resistant, and flame retardant, ensuring safe and reliable operation. 4、GOOD PERFORMANCE: Integrated IGBT module is adopted, with strong load carrying capacity and good stability, dual row digital tube display, has large low frequency torsion. 5、MACRO FEATURE: Can realize the one button constant pressure water supply macro, engraving machine macro, and machine tool macro function, which is efficient and stable. Item Type: Frequency Inverter Material: Flame Retardant ABS Input: 1PH AC220V±15% 14.0A 50-60Hz Output: 3PH AC0-220V 7.0A 0-400Hz Power Capacity: 3.0KVA Suitable Motor: 1.5KW 2HPOvervoltage 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.
