Three-phase output reactors for frequency converters are designed for 3 x 400 V / 230 V, 50 Hz networks. It´s produced in accordance with ČSN EN 61 558-2-20 with insulation class F and maximum ambient temprerature of 40 °C. The reactor series are designed with rated current and inductance values shown in the table below. Where higher inductance is required, the reactors can be connected in series. Motor (output) reactors are connected between frequency converters and are powered motors. They reduce the capacitor current produced when using long motor cables and prevent converter overloading. At the same time, reactors reduce noise voltage emissions from the converter and line output. This is why reactor should be placed as close to the converter as possible.
If you require a reactor designed to match specific requirements, please specify: current In (A), thermal current Ith (A) or content of upper harmonics (effective value or %), frequency f (Hz), inductance L (mH) or voltage loss on the reactor Ux (V) and effective or peak linearity (saturation current) Isat (A), unless it is equal to the rated thermal current. Additional parameters such as maximumloss can also be specified.
