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: 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 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 Distance Output voltage Charging for 4.2V lipo battery current 1mm 5V 600mA 2mm 5V 450mA 3mm 5V 360mA 4mm 5V 310mA 5mm 5V 240mA 6mm 5V 210mA 7mm 5V 162mA 8mm 5V 150mA 9mm 5V 132mA 10mm 5V 120mA 11mm 5V 110mA 12mm 5V 70mA 13mm 5V 54mA 14mm 5V 41mA 15mm 5V 28mA 16mm 5V 19mA 17mm 5V 17mA 18mm 5V 10mA 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 Transmitting circuit diagram: Low temperature circuit: Receiver board circuit diagram:
