V1.0 Page 1 of 11 Report No.: CTL2203256011-MPE ___________________________________________________________________________ Page 1 of 11 RF Exposure Evaluation Report 1. Product Information FCC ID: 2A5Z9-DN49 Product Name Portable Solar Charger Model Number DN49 Power Supply Input: 5V3A, 5V2A Output: 5V3A, 5V2A Solar Panel: 5V/300mA Wireless Charging: 5W Modulation Type CW (Continuous Wave) Frequency Range 115 –205 KHz WPT Operation Frequency 124.5KHz Antenna Type Coil Antenna Maximum Rated Power of WPT 5W Exposure category General population/uncontrolled environment EUT Type Production Unit Device Type Mixed Mobile and Portable Device 2. Evaluation Method Per KDB 680106 D01 Section 3. RF Exposure Requirements; 1) Consumer wireless power transfer devices approved under Part 18 in some cases have to demonstrate compliance with RF exposure requirements. The potential for exposure must be assessed according to the operating configurations of the wireless system and the exposure conditions of users and bystanders. RF exposure must be evaluated with the client device(s) being charged by the primary at maximum output power. The RF exposure requirements must be determined in conjunction with the device operating characteristics, according to the mobile and portable exposure requirements in Section 2.1091 and Section 2.1093 of the rules. SAR and MPE limits do not cover the frequency range for wireless power transfer applications which operate below 100 kHz and 300 kHz respectively; therefore, RF exposure compliance needs to be determined with respect to 1.1307 (c) and (d) of the FCC rules. 2) Based on the design and implementation of the power transfer application, it must be clearly identified if mobile or portable RF exposure conditions apply. Devices that are installed to provide separation of at least 20 cm from users and bystanders may qualify for mobile exposure conditions. For some conditions where users and bystanders may be exposed at closer than 20 cm, section 2.1091(d) (4) of the rules may apply. 3) For devices designed for typical desktop applications, such a wireless charging pads, RF exposureevaluation should be conducted assuming a user separation distance of 15 cm. E and H field strengthmeasurements or numerical modeling may be used to demonstrate compliance. Measurements shouldbe made from all sides and the top of the primary/client pair, with the 15 cm measured from thecenter of the probe(s) to the edge of the device. Emissions between 100 kHz to 300 kHz should beassessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63 A/m. A KDBinquiry is required to determine the applicable exposure limits below 100 kHz 4) Portable exposure conditions from 100 kHz to 6 GHz are determined with respect to SAR requirements. Existing SAR systems and test procedures are generally intended for measurements above 100 MHz. While numerical modeling can be an alternative, the constraints of substantial computational resources at low frequencies could introduce further limitations. Under these circumstances, including operations below 100 kHz, the Commission may consider a combination of analytical analysis, field V1.0 Page 2 of 11 Report No.: CTL2203256011-MPE ___________________________________________________________________________ Page 2 of 11 strength, radiated and conducted power measurements, in conjunction with some limited numerical modeling to assess compliance. 5) Depending on the operating frequency, existing SAR and MPE measurement procedures may be adapted to evaluate wireless power transfer devices for compliance with respect to mobile or portable exposure conditions. If the grantee or its test lab have any questions regarding RF exposure evaluation they should contact the FCC Laboratory with sufficient system operating configuration details to determine if RF exposure evaluation is necessary and, if required, how to apply specific test procedures. Below 100 MHz, when SAR testing is required and the device is operating at close proximity to persons, information on device design, implementation, operating configurations, exposure conditions of users and bystanders are needed to determine the evaluation and testing requirements. In addition, the influence of nearby objects may also need consideration according to the wireless power transfer system implementation; for example, the effects of placing the device, its coils or radiating elements on or near metallic surfaces 6) According to April 2018 TCB Workshop, No need to report E-field measurements. Only H-field required. 3.
