Approx.–70%Reusing EnergyRegenerative Converter (PCNV) (Optional) Elevators usually travel using power from a power supply (powered operation); however, when they travel down with a heavy car load or up with a light car load (regenerative operation), the traction machine functions as a power generator. Although the power generated during traction machine operation is usually dissipated as heat, the regenerative converter transmits the power back to the distribution transformer and feeds it into the electrical network in the building along with electricity from the power supply. Compared to the same type of elevator without a regenerative converter, this system provides an energy- saving effect of approximately 35%.*Energy-saving effects: Approximately 35%.*MotorControl panel & regenerative converterIn addition, the regenerative converter has the effect of decreasing harmonic currents.Distribution transformerPower supply
