Energy recovery system ZArec4C 013

Overview
The ZArec4C power feedback unit recovers generator energy produced during elevator travel and feeds it back into the supply network. Its extremely flat design enables wall mounting in the machine room or inside the lift shaft, and it is optimised for the short, highly dynamic regenerative cycles typical of elevator systems.

Key features

• Recovers generated energy and returns it to the supply network to improve system energy efficiency
• Designed specifically for brief, highly dynamic regenerative operation typical of elevator applications
• Sinusoidal regenerative output through integrated EMC components (low distortion)
• Extremely flat / ultra‑slim design suitable for wall mounting in machine room or shaft
• Distortion factor THD < 5 %
• No additional brake resistor required for evacuation runs

Applications

• Cable elevators with asynchronous or synchronous motors
• Wall mounting above landing doors or between guide rails depending on version
• Machine room or elevator shaft installation for space‑constrained sites
• Typical converter compatibility: frequency inverter up to 32 A
