Stores the energy that the elevator wastes when the motor brakes to return it during the next consumption run. Energy savings of up to 70% without harmonic distortion and without additional stand-by consumption with a simple two-wire connection to each drive.

ERS 2G is a bidirectional high-efficiency DC/DC converter that integrates an energy storage module of ultracapacitors. A very simple connection of ERS 2G to any VVVF drive is enough to convert the elevator into a regenerative elevator with storage.

In detail:

- Simply connecting it to the drive's DC link is enough for the system to automatically store the energy in the supercapacitors when it is generated and return it when it is consumed.

- Supercapacitor modules offer better power density and cycle stability than batteries. They are therefore the best possible solution for fast charging and discharging applications such as elevators.

- Ultracapacitors are maintenance-free.

- Easy integration into both new and existing elevators without the need for replacement.

Advantages of using ERS 2G:

- Recovers and stores the energy generated by the elevator to return it during the next consumption run or to support the drive's standby mode.

- No feedback to the grid. No harmonic problems.

- Providing an improvement in the efficiency classification of the elevator.

- The elevator actually consumes less energy from the grid.

- Very simple two-wire connection to any drive, new or existing.
