Elevator energy feedback

Elevator energy feedback feeds back the regenerative energy generated during the process of motor speed regulation to the power grid, avoiding the energy loss caused by conventional energy consuming braking units due to resistance heating, thus achieving considerable energy-saving effects.

Input Reactor

AC L series reactors, also known as power coordination reactors, are used to connect in series with the input terminals of fully digital DC speed governors and frequency converters. They are connected between the power supply and frequency converters, and can limit the impact waves caused by grid voltage sudden changes and operating overvoltage, effectively protecting the frequency converter, improving the power factor of the frequency converter, and suppressing the harmonic current input by the frequency converter into the grid.
