Feature:1. Overcurrent Suppression Protection: The variable frequency inverter automatically limits the load current from exceeding the set overcurrent suppression point during operation through real time monitoring of the load current to prevent fault tripping caused by excessive current, this function is especially suitable for some loads with large inertia or drastic changes.2. Excellent Stability: The variable frequency drive uses integrated IGBT modules for greater load carrying capacity and stability.3. Compact Internal Design: The new, upgraded design of the variable frequency drive makes it more compact, allowing for more space saving installation and reducing costs by increasing the number of inverter installations in the cabinet.4. One Key Macro Function: The frequency inverter can be used for machine tool macros, engraving machine macros and constant pressure water supply macros, making them easier to operate and more efficient and stable.5. Overvoltage Suppression Protection: When the voltage of the bus bar of the inverter reaches or exceeds the bus bar overvoltage suppression point during operation, the inverter will automatically adjust the operating frequency to suppress the bus bar voltage increase, thus ensuring that the inverter will not be protected from overvoltage caused by the high bus bar voltage.6. Reliable Material: The variable frequency inverter is made of industrial flame retardant ABS plastic that is excellent impact resistant, heat resistant, flame retardant, secure and reliable.7. Wide Application: The variable frequency drive is widely used for speed regulation of all kinds of 3 phase asynchronous motors to achieve motor speed regulation, energy saving and environmental protection, improve production processes, increase production efficiency and other functions.8. Double Row Digital Tube: The variable frequency drive has a separate air duct design for reliable stability, a double row digital display and high torsion at low frequencies.Specification:Item Type: Variable Frequency DriveMaterial: Flame Retardant ABSModel: SKI90 011G, 015P 4Input: 3PH AC380V15% 26A 50 to 60HzOutput: 3PH AC0 380V 25A 0 to 400HzPower Supply Capacity: 17KVAApplicable Motor: 11KW 15HPCategoryTerminal symbolsSegment NameFunction descriptionPower Supplies10V GNDExternal and 10V Power supplyProvides and 10V external power supply, maximum output current: 150mA (with short circuit protection)Generally used as an external potentiometer working power supply.Potentiometer resistance range: 1k to 5k24V COMExternal and 24V power supplyExternal and 24V power supply, generally used for digital input and output terminalsPower supply and external sensor power supplyMaximum output current: 200mAAnalogue terminalsAl1 GNDAnalog input terminal 11.
