ZArec - Power feedback unit
In a typical elevator system, the unused energy generated during travel is converted by a brake resistor into waste heat. From an environmental perspective, this approach is put into question by increasing resource scarcity, rising energy costs and the resulting increasing demands for energy efficiency and sustainability, which require ways of using the unexploited energy potential. The use of the ZArec4C regeneration unit takes these demands into account. The generated energy is stored and fed back into the supply network. The ZArec’s extremely flat design makes it ideal for wall mounting in the machine room or lift shaft.
Properties and special features:
With the ZArec power recuperation unit the demands for energy efficiency and sustainability of elevator systems are met. The generated energy is stored and fed back into the supply network.
ZArec has been developed especially for brief, highly dynamic regenerative operation, such as that which occurs in elevator systems.
Applications and areas of use:
- Cable elevators with asynchronous or synchronous motors
- Ultra-slim design
- For wall mounting in machine room or the elevator shaft
- Sinusoidal regenerative power from integrated EMC components
- Distortion factor THD: < 5 %
- No additional brake resistance for evacuation runs
