Feature: 1. SPACE SAVING DESIGN: Inverter adopts independent air duct design, stable performance is superior. Interior upgrade design, more compact, saving more installation space 2. WIDE APPLICATION：Inverter is widely used in all kinds of three phase asynchronous motor speed regulation, to achieve motor speed regulation, energy saving and environmental protection, improve the production process, improve production efficiency and other functions 3. OVERVOLTAGE SUPPRESSION PROTECTION: When the busbar voltage reaches or exceeds the busbar overvoltage suppression point during the operation of the converter, the converter will automatically adjust the running frequency suppression busbar voltage rise, so as to ensure that the converter will not cause overvoltage protection due to high busbar voltage 4. OVERCURRENT SUPPRESSION PROTECTION: During operation, through real time monitoring of the load current, automatically limit does not exceed the set overcurrent suppression point, in order to prevent the fault trip caused by too much current. For some large inertia or drastic changes in the load, this function is especially suitable 5. SAFE AND FLAME RETARDANT: Vector converter is made of industrial flame retardant ABS plastic, which features high impact and heat resistance, high flame retardant, and high safety and reliability 6. STRONG AND STABLE: Vector converter has double row digital display, high low frequency torsion. Integrated IGBT module is adopted, which has stronger carrying capacity and better stability 7. MULTIPLE FUNCTIONS: Universal VFD can achieve one key constant pressure water supply macro, engraving machine macro, machine tool macro function, easy to operate, efficient and stable Specification: Item Type: Vector Frequency Converter Material: Flame retardant ABS Input: 3PH AC380V±15% 3.4A 50-60Hz Output: 3PH AC0-380V 2.1A 0-400Hz Power Supply Capacity: 1.5KVA Adaptive Motor: 0.75KW 1HP Category Terminal symbol Terminal name Function description Power supply 10V-GND External +10V power supply "External supply +10V power supply, maximum output current: 150mA (with short circuit protection) Generally used as an external potentiometer working power supply, Potentiometer resistance range: 1kΩ~5kΩ" 24V-COM External +24V power supply "To provide external +24V power supply, generally used as a digital input/output terminal work Power supply and external sensor power supply Maximum output current: 200mA" Analog terminal Al1-GND Analog input terminal 1 "1.
