Description
Three-phase Motor Output Choke 330A, 380V, 160 kW, 0.021 mH OCL-0330-021U-0.4SA is installed at the output of the frequency converter to filter the current supplied to the three-phase electric motors 380V. The purpose of the output electrical choke is as follows:
- Creating inductive resistance that limits the motor's power current and thereby prevents overload and damage;
- Preventing abrupt current surges during the motor start-up, which can lead to equipment failure;
- Cleaning the current sinusoid from unwanted high harmonics (high-frequency noise) occurring in the drive.
Use the AC output choke in the circuit between the frequency converter and the asynchronous motor to improve the power quality of the drive, as well as secure and long-lasting equipment operation.
