RF Exposure Info

FCC RF Exposure Evaluation Per Section 5 of FCC KDB Publication 680106D03 Inductive wireless power transfer applications that meet all of the following requirements are not required to submit a PAG for equipment approved using certification to address RF exposure compliance: 1) Power transfer frequency is less that 1 MHz Device operates nominally at 127.9 kHz (123.7 – 131.7 kHz range). 2) Output power from each primary coil is less than 15 watts The EUT is a WPC Power Class 0 device following the Wireless Power Consortium design specifications for a device operating at 15 watts. 3) The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that are able to detect and allow coupling only between individual pairs of coils This device is designed to comply with this requirement. 4) Client device is inserted in or placed directly in contact with the transmitter This device is designed for direct contact charging only. 5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). The EUT is Mobile (not portable). f) Aggregate leakage fields at 15 cm surrounding the device and 20 cm from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit. Aggregate leakage fields at 15 cm distance surrounding the EUT and at 20cm above the EUT pad antenna were measured with each integral coil loaded by a Samsung Galaxy 6 Edge cellular phone and, over three charging levels (1%, 50%, 99%). Results noted in the following pages demonstrate that these fields remains well below 50% of the MPE limit.
