FIN900 Three Phase Choke
2Pages

APPLICATION GUIDE The FIN900 and FIN930 common mode choke series are used to reduce high frequency interference caused by pulse wave modulation of power transistors. Chokes round out the fast voltage rise time and reduce high frequency (radio frequency) electromagnetic interference radiated into the environment without appreciable line voltage drops. Chokes are usually connected between the inverter, or the controller, and the motor. It is recommended to run a shielded cable between the choke and the motor with the shield connected to ground at both ends. This configuration combines the effect of the inductance of the coil and the distributed capacity of the cable shield. An advantage to using a choke installed between the controller and the motor is the reduction of conducted interference emitted from the device towards the main and characterized by frequencies between 1 and 3 MHz. Enerdoor common mode choke series is recommended for servo drive applications and variable frequency drives with close loop systems.
