The energy feedback reactor generally used often in the electrode of 2 phase and 4 phase power limit limit state of the work, such as to achieve better, this part of the energy grid or directly through the inverter DC bus is the inverter load absorption and utilization, in the process of reactor mainly to filter, pressure, shock and prevent inrush current maximum limit. Sine wave output voltage and current, in the elevator, port crane, derrick etc. generally, our company produces energy feedback reactor of silicon steel sheet and high temperature wire made by high quality cold-rolled, high dynamic thermal stability capability, stable / low noise characteristics of inductance, current level 5A-1500A optional.
