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:

Transmitter module (yellow shell) size: length 18mm * width 8.5mm * height 15mm Coil size: outer diameter 38mm inner diameter 30mm thickness 1.6mm Total length of the transmitting module: 10.2 CM Line length of positive and negative pole: 6 cm Input DC voltage: 12VDC Input current: 100mA - 500mA

Receiver module (small board) size: length 26mm * width 5mm * thickness 3mm Coil size: outer diameter 38mm inner diameter 30mm thickness 1.6mm Total length of receiving module: 17 cm Line length of positive and negative pole: 6 cm Output voltage: 5VDC Output current: 500mA - 600mA Output power: 2.5W - 4W Transceiver distance: 5 ~ 10mm 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 If receiving distance increase it's need to add the coil turns. In practical application, it can change the turns of coil to adjust the power.

Note:

Because the product unceasingly to improve, some module circuit board a few place may and physical map slightly difference, but guarantee function is the same.

Package included:

1 x Wireless charger transmitter module 1 x Wireless charger receiver module

Connection method:

Pin 1 connected to the negative pole of the power supply; Pin 2 connected to the positive pole of the power supply; Pin 3 and 4 connected to the external transmit coil
