Features1. Improve the input current wave caused by capacitor harmonics.2. Reduce and prevent rectifier bridge damage and capacitors.3. Overheating due to a surge in current.4. Improve the power factor and reduce the AC pulse of the DC bus.5. Limit transient changes in system voltage.
Dimension (unit: mm)Tips: Starting reactor function
AC asynchronous motors have a large starting current, which is 5-7 times the rated current. Therefore, when a large motor is started, it will cause a large voltage drop on the power grid and have a greater impact on the line's electrical equipment. The voltage reduction method is usually used to limit the starting current of the motor. Reactors can be started in series on the motor's line in the case of reduced voltage starting. Generally, the power of the matched motor is 220KW-4800KW.
