Input voltage: 12V. ^^
Receive output voltage and current: receive output 12V/1A when 5mm.
^^ Transmitting coil size: outer diameter 43mm, thickness 2.3 mm;
Transmitter module size: 16mm*24mm.
^^ Receiving coil size: outer diameter 43mm, thickness 2mm;
Receiver module size: 10mm*25mm*3mm. ^^ Note that the transceiver modules must not be used when the distance is below 4mm! Otherwise the receiving module will be damaged by the overvoltage!
