Proxi-Ring 240W

Features

  • Proxi powered wireless slip ring
  • Transfer power through any non metallic material including liquids, solids and gases
  • Unlimited continuous rotation
  • Corrosion and water proof – immersion rating of IP67
  • Max continuous power is 150 W, max combined peak power is 240 W (combination of min output and GPIO outputs)
  • Independent over current protection for each output
  • Corrects low voltage input to provide ±5 % output regulation
  • Plug and play system compatible with existing power supplies and communication protocols
  • 100 Rpm maximum angular velocity

Description

The Proxi-Ring™ is a standalone electrical device that enables transfer of power across an electrical rotary joint referred to as a slip ring, electric swivel, rotary electrical interface, commutator or a collector.

The Proxi-Ring™ is a next generation solution to replace existing mechanical slip rings. It provides a reliable and maintenance free alternative and does not require friction based metal and/or carbon brush contacts to enable power and data transfer*.

Input power is transferred inductively. A standard 24 VDC power supply can be used to power the PR240W power transmitter. Up to 10 A peak can be drawn from the PR240W power receiver. The output voltage is held within a tight ±5% tolerance.

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

Benefits

  • Full contactless design – elimination of friction or heating between rotating and stationary circuit contacts
  • Cost-effective maintenance-free alternative to traditional slip rings
  • Solve continuity of power delivery and maintenance problems
  • Simplify implementation/installation processes
  • Create unique competitive advantages in the design, operation and convenience of your products
