DC Choke

This is used to improve the input power factor of the inverter power supply, reduce harmonicsor suppress external surges.Install this option when the power supply capacity is 500 kVA or more and the power supply capacity is 10 times or more than that of the inverter’s capacity, or when a distortion generating source such as a thyristor or a large-capacity inverter is connected to the same wiring leads.
