2.2 Specifications of Secondary Module
2.2.1
Overview of Specifications
This chapter describes the specifications of the primary module (module on the primary side) that belongs to
the noncontact power transmission modules.
The main function of the primary module is to convert power supplied by AC adapter into magnetic energy
and transmit it to the secondary module (module on the secondary side).
The module has the following functions allowing for safety charging process.
♦ Detection of foreign metal objects
♦ Detection of abnormal temperature
