Specifications

4：If the module detects an exception on the tablet PC receiver, The module will stop

working, at this point, you need to move the tablet PC away from the launch, put the

tablet PC on the launch module again to enter the charging state.

SEVEN．The usage environment of wireless charger

A. LAUNCHING BASE

1、The principle of wireless charging is to convert direct current into

electromagnetic field, and then send the electromagnetic field up. The general

launch distance is 2-7MM. Left and right deviation center point can’t exceed 7MM,

the received current will be small or can’t establish a direct connection if more than

7MM.

2、The conversion efficiency is low when the distance is offset, under normal

circumstances, the current received by the vertical offset of 1MM is reduced by

100MA, the current received by a lateral offset of 1MM is reduced by 150MA,

efficiency will also drop below 70%.

3、Strong magnetic interference, please make sure there is no magnet within

20mm of the surrounding environment. The transmitting power will be reduced if

there exist a magnet, this will directly affect the use effect。

4、Metal interference, please don’t allow metallics on the surface of the launch

base, the metal on the base must dig a hole that is 15mm greater than the radius of

magnetic separator of the transmitting coil if it can’t be avoided according to the

structural requirements. This is to prevent electromagnetic fields from cutting meta,

it causes abnormal operation of the transmitting base and power loss.
