REO is an original manufacturer of high quality power equipment, including electronic controllers, components and electrical regulators.
NIEKE line chokes are used to meet EMC requirements by reducing the voltage rise (dV/dt) and inrush current, thus ensuring a reliable power supply to railway carriages.
For drive applications NIEKE also supplies single and three-phase line chokes for a 1%, 2% or 3% voltage drop and these are used for reducing harmonics.
