Technical specifications
Description
Three-phase motor choke 50A, 380V, 18.5 kW, 0.14 mH OCL-0050-0M14-0.4SC is installed at the output of a frequency converter to filter current supplied to three-phase electric motors 380 V. The purpose of the output electric choke is as follows:
- Creation of inductive resistance that limits the motor power current, thus preventing overload and damage;
- Prevention of sharp current surges during motor start-up, which can damage equipment;
- Cleaning the current sine wave from undesirable high harmonics (high-frequency noise) that occur in the electric drive.
Use an AC output choke in the circuit between the frequency converter and the asynchronous electric motor to improve the power supply quality of the drive, as well as for the safe and long-term operation of the equipment.
