PowerbyProxi Wind Solutions

PowerbyProxi offers the first contactless slip ring that provides power and data wirelessly to pitch control systems in wind turbines. A reliable and maintenance-free alternative to mechanical slip rings, the Proxi-Ring does not require friction-based metal or carbon brush contacts to enable power and data transfer.

Proxi Ring Features

Proxi-Ring powered wireless slip ring solutions provide:

  • Friction-free circuits
  • Fast accurate responses to load variations
  • Power channels: Maximum output current 10A (total across all channels) at 24VDC
  • Communication channels: Fully integrated data communication using all major protocols
  • Energy efficiency of 90% – Comparable with hard wired solutions

Ideal for Wind Turbine Vendors, Operators and Maintenance Providers

The Proxi-Ring is available as a plug-and-play modular system, which can be used to upgrade existing slip rings in new or existing equipment.

  • Eliminate friction or heating between rotating and stationary circuit contacts
  • Cost-effective, maintenance free alternatives to traditional mechanical slip rings
  • Include no moving parts that can fail or cause false resets
  • Provide unlimited and continuous rotation speeds
  • Highly corrosion resistant and waterproof
  • Compatible with existing power supplies and communications protocols
