Wireless Power Supply Coil Module Wireless Charger Module

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 0.6 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
