High-performance backup power supply for mains failure. Energizes the elevator for a large number of trips and extended time enabling complete building evacuation.
System that supplies energy to the elevator in case of mains failure. More than a UPS because it keeps the elevator energized for a large number of trips to any floor making safe and complete evacuation of buildings possible. This high-performance auxiliary supply system keeps the elevator running for hundreds of trips without mains. The system keeps the control informed in every moment about the state-of-charge of the batteries.
The installation is very simple, even for existing elevators with no additional cabling to floors.
Advantages of using E3
- Simple connection and easy adaptation to any lift, even for modernization.
- The elevator controller keeps full control of the system and the elevator (no additional control)
- 48 V battery pack for all models with a constrained size and easy and low-cost maintenance.
- Regenerative. Recovers the energy generated by the elevator and stores it in the batteries thus expanding the duration of the evacuation time.
- Alternative to traditional backup auxiliary systems. Suitable for new or existing elevators due its simple installation and adaptation.
The system comprises
- Auxiliary supply for mains failure, providing:
- 600 Vdc for the drive
- 230 Vac for control, brakes, door operators, etc.
- Low power input to maintain the accumulator fully charged
- 48 V batteries, similar for all models. Low cost and low maintenance. The system provides information to the controller about state-of-charge during the complete evacuation process.
Product range and technical features
Case studies
The use of less power from the grid or the reduction of the overall energy consumption can be achieved with battery and/or supercapacitor powered DC/DC converter-based solutions.
AGVs & shuttles (supercapacitor powered)
Bidirectional DC/DC converters applied to shuttles allow energy consumption from supercapacitors and charge from the grid with only one component. Electrified monorails become unnecessary in warehouses.
Logistics – AGVs (battery powered)
Reduction in size, cost and weight in battery powered industrial vehicles through DC/DC converters. DC motors are removed in favour of AC more standard and smaller solutions.
A hybrid powered solution for cranes achieve reductions in fuel consumption, size of generator and braking resistor bank. Energy stored is used by a DC/DC converter to counterweight the power requirements and save the braking energy.
Electronic counterweight and peak shaving can be provided by a bidirectional DC/DC converter-based solution working with batteries and/or supercapacitors.
Combine a traditional fuel generator with a battery- powered system based on DC/DC to make a hybrid boat. Charge your batteries from the wind and move the boat freely without the need for it in the harbour.
Off-grid solar panel powered solution to feed hydrogen fuel cells through isolated DC/DC converters. Each converter provides MPPT per solar string to achieve highest efficiency.
Flexible solution for grid-connected hydrogen fuel cells through isolated DC/DC converters. High efficiency, robustness and easy parallelization for infinite combinations of power requirements.
