The power of etaLINK. Why your customer will love etaLINK and Wiferion.
With their extensive experience in the field of power electronics, Wiferion has supported the development of numerous power converter systems for the e-mobility, energy storage and renewable energy sectors.
CW1000: Wireless charging with 1000 Watt
The new CW1000 system from Wiferion with 1kW is based on our many years of experience and expertise in the field of efficient energy supply. This has enabled them to develop a contactless charging system that combines electronics and coils. As a result, the system offers numerous advantages such as a compact design, intelligent energy supply and a cost-efficient and reliable power supply for small robots. The system can simply be connected directly to the battery, making it a particularly simple and practical solution.
etaLINK 3000: Wireless charging with 3000 Watt
etaLINK 3000 is a patented inductive charging system for industrial electric vehicles and mobile robots. Wiferion’s charging systems are designed for the latest generation of smart and autonomous robotic systems. Easy and independent to install, they provide the vehicles with all relevant data. Since the systems do not require plug-in or sliding contacts, they enable intermediate charging of the batteries. This so-called “in-process charging” not only saves time, but is also safer than charging via potentially dangerous open contacts. etaLINK charging systems are maintenance-free and designed for many years of continuous use, e.g. in logistics or production. Furthermore, the inductive charger works with any type of battery.
