Voltage Stabilizer: The inverter has a built in 3 phase high accuracy automatic AC voltage stabilizer, which can automatically keep the output voltage constant when the grid voltage changes within ±10%. High Performance: The inverter adopts PID control unit, which has fast operation speed and short response time, can quickly the equilibrium value, and supports online switching of torsion and speed control. Multiple Control: With VF control, non inductive vector control, switching flux vector control, open loop torsion control, PG vector control, etc. The advanced current sampling mechanism enhances safety. PLC Function: With multiple speed running function, simple PLC function can be realized through custom control terminals, up to 16 speed operation and 4 stage acceleration can be set. Parameter Settings: No complicated and cumbersome parameter setting is required, through type selection, quick G type and P type load adjustment is realized, and appropriate parameters are automatically set. 7 Frequency Sources: There are keyboard setting, analog voltage setting, analog current setting, multi speed running setting, PID control setting, remote communication setting, keyboard encoder and other frequency sources. High Efficiency: Adjust the output voltage by automatically detecting the load current for maximum efficiency control, suitable for fans, pumps and other mechanical equipment. Item Type: Variable Frequency Drive Material: PC Storage Temperature: -25-40? Input Voltage: 3 Phase AC380V Output Voltage: 3 Phase AC380V. 1 x Variable Frequency Drive. Pay attention to the safety of electricity when using, please check the manual, or operate under professional guidance.
