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. ENERGY RECOVERY SYSTEM FOR LIFTS ADVANTAGES » 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. » Bidirectional high-efficiency DC/DC converter integrating energy storage module of ultracapacitors. » Very simple connection of ERS 2G to any VVVF drive is enough to transform the elevator to a regenerative one with storage. » 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

One single system achieves energy savings up to 70%. plug & save Measurable and accessible energy savings. Data obtained in a real elevator before and after installing ERS 2G. » Easily transformation of any elevator into a regenerative one. » Up to 70% savings of the energy consumed by the motor. » Suitable for new or existing elevators. Energy Saved » Improves energy classification of the lift. How is energy generated? In electric traction elevators that include VVVF drives, also known as inverters, the generated energy is wasted in the form of heat in a braking resistor. ERS 2G is capable...
