Epson Air Trans - Wireless Power Transfer

AirTrans technology can be used to transfer power over a short distance through the air.

Through its high energy efficiency and small size compared to traditional solutions it will allow the creation of new applications.

One AirTrans set consists of a primary module which is connected to the main power supply and a secondary module which receives the energy and outputs a stable 5V voltage to the target circuit.

Features

  • 5.0V input, 5.0V output / 100mA max.
  • ID authentication
  • Period authentication
  • Foreign object (metal) detection
  • On/off by switch
  • Full-charge detection
  • Removal detection
  • Safety features:
  • low input voltage, timer stop, driver failure, built-in fuse
  • Operation state output by LED

Applications

  • Fast charging waterproof equipment
  • Completely sealed equipment
  • tamper proof, explosion safe, rough environment
  • Several devices sharing the same charger
