3Pcs Wireless Power Supply Coil Charger Board Wireless Charging Module
Tax included.
Description:
Wireless power supply technology(wireless charging) allows the receiver only across the air, paper or plastic housing can achieve the transmission of electrical energy, indeed greatly facilitate the application.
Specification:
Input voltage: DC 12V
Input current: 100mA - 500mA
Output voltage: DC 5V
Output current: 500mA - 600mA
Output power: 2.5W - 4W
Center resonant frequency: 125KHz
Feature:
Emission coil and receive coil distance for 1mm ~ 20 mm, if small current work can be appropriately increase receiving coil turns to increase transmission distance
Test data, for reference:
Emission coil: copper wire diameter φ0.6 mm, coil diameter 40 mm, around 20 turns
Receiving coil is same
Emission coil grafted in 12V power supply: standby working current 300mA, load is 4.2V 800mAH polymer lithium battery
