Energy recovery system ERS 2G

Stores the energy wasted by the elevator when motor brakes to return it in the next consumption trip. Energy savings up to 70% with no harmonic distortion and no added stand-by consumption with a simple two-wire connection to any drive. ERS 2G is a bidirectional high-efficiency DC/DC converter integrating energy storage module of ultracapacitors. A very simple connection of ERS 2G to any VVVF drive is enough to transform the elevator to a regenerative one with storage. What is it Only the connection to DC link of the drive is enough for the system to automatically store the energy in the supercapacitors when generated and return it when there is a consumption. Supercapacitor modules offer better power density and cycling features than batteries. Therefore, they are the best possible solution for fast charging and discharging applications such as in elevators. Ultracapacitors require no maintenance. Simple integration both in new or existing elevators with no need for replacements. Advantages of using ERS 2G Recovers and stores the energy generated by the elevator to return it in the next consumption trip or to support the drive’s standby. No regeneration to the grid. No harmonic problems. Granting improvement of the efficiency classification of the lift. Elevator actually consumes less energy from mains. Very simple two-wire connection to any drive, new or existing.
