50 HZ LINE CHOKES

Line chokes are usually series connected to an electrical load. Single and three phase versions are available. They are intended to provide the following important protective functions:

• Suppression of harmonic currents resulting from frequency-dependent inductive resistance
• Soft start for electrical loads for reduced component stress, e.g. in rectifier circuits
• Guaranteed short circuit voltage of 4% of the mains voltage (uk = 4%) as generally required from power supplier companies
