AC REACTOR (OUTPUT REACTOR & INPUT REACTOR)
It is installed at the output end of the inverter to limit the capacitive charging current of the cable connecting the inverter and the motor, and to passivate the voltage rise rate of the PWM wave output by the inverter. When the motor cable length exceeds a certain value, it is recommended to insert a motor reactor between the inverter and the motor. It is used to compensate the capacitor recharging current when the wire is long. This larger length depends on the rating of the inverter and the type of motor cable.
application:
1. Limit dv/dt to 500V/us
2. Limit the overvoltage on the motor terminals to: 1000V to 400V~ (rms value)
1150V to 460V~ (rms value)
3. Filter interference caused by opening the contactor between the filter and the motor
4. Reduce motor ground leakage current
Technical specifications:
1. Working voltage: Ф3/380VAC-1140VAC
