A DC Reactor is used to improve the input power factor of the inverter power supply and reduce harmonics.
We suggest installing this option when the variable frequency inverter is rated more than 90KW. The power supply capacity is 10 times or more than that of the inverter’s capacity. Alternatively when a distortion generating source such as a thyristor or a large-capacity inverter is connected to the same wiring leads.
The DC reactor is more effective than the input reactor in improving the power factor.
We recommend joint use of the input reactor, that is effective in suppressing external surges, when facilities where the inverter is to be applied require high reliability.
Gator Products supplies standalone DC reactors from 0.75kW right up to 450kW.
