|Input||12V /9V /5V|
|Port||1 x USB|
|Certificate||CE FCC ROHS|
This approval sheet describes the detail of the 5W digital demodulation wireless electrical,
Function and physical characteristics of charge transmitter, compatible with WPC - Qi V1.2.3
Standards, support for transmitting andreceiving bi-directional.
1.1The application block diagram
2. Input Characteristics
2.1 Input Voltage
Input Voltage range: 12Vdc ± 5%.
2.2 Input Current
In the case of full load, Input 5Vdc the highest input current 1A.
2.3 Stand-by Power Consumption
In the case of the standby, Input 5Vdc, the loss is lower than 0.2W.
2.4 Dynamic Power Lock
Input power belong to the weak power souce , ( Input power is not enough), the transmitter must offer the power output.
3. Output Characteristics
The output voltage, output current meets the following criteria:
|Output Voltage:Normal/Fast Charge||+5V or 9VDC|
In the case of receiver output short circuit, the transmitter stops working, when the receiver is removed, the transmitter will return to normal work.
2.Over Current Protection
When the receiver output current is higher than 1.1A, the transmitter stops working and the transmitter will return to normal operation when the receiver is removed.
3.Parasitic Metal Object Detect
When the transmitter coil is detected the metal larger than the coin size , the
transmitter stops working.and the transmitter returns to normal working after the metal i
4.Foreign Object Detect
In the case of the normal work of the transmitters and receivers, the coin size metal is
inserted between the transmitting coil and the receiving coil. The transmitter must be
stopped within 2 minutes (the receiver protocol version requires WPC1.1 or above).
In the case of the normal work of the transmitters and receivers, receiver coil position
relative to the transmitter coil displacement , causes transmitter coil over voltage,and
transmitter must enter the current limit mode, in order to protect the transmitter.
