Jakarta (Jten) – Wireless Power Transmission (WPT) technology is increasingly developing and is used in various electronic devices such as wireless chargers, electric vehicles, and medical devices. However, to ensure safety and efficiency of use, the Indonesian government has updated related regulations by issuing KEPMEN 46 of 2025 as a replacement for KEPMEN 260 of 2024.
Changes to WPT Regulations in KEPMEN 46/2025
This new regulation regulates several important aspects, including:
✔ New Frequency Bands – Safer and more efficient spectrum adjustment.
✔ Strong Limits of Electromagnetic Fields – Reduces the potential for interference to other devices.
✔ Spurious Emission – Limiting unwanted emissions so as not to interfere with radio communications.
✔ Testing Standards – Using international methods to guarantee the quality of the device.
New Frequency Bands for WPT
The latest regulations set the frequency spectrum for WPT to be more structured and less interference:
- 100 – 148,5 kHz
- 315 – 405 kHz
- 1700 – 1800 kHz
- 6765 – 6795 kHz
- 13,553 – 13,567 MHz
Strong Limits of Electromagnetic Fields
In order for the WPT device not to interfere with other devices, the strong limit of the electromagnetic field is set as follows:
- 100 – 148.5 kHz: ≤ 66 dBμ/m at 10 meters
- 315 – 405 kHz: ≤ -5 dBμ/m at 10 meters
- 1700 – 1800 kHz: ≤ -5 dBμ/m at 10 meters
- 6765 – 6795 kHz: ≤ 42 dBμ/m at 10 meters
- 13,553 – 13,567 MHz: ≤ 60 dBμ/m at 10 meters
WPT Testing Method Based on KEPMEN 46/2025
To obtain official certification, WPT devices must go through rigorous testing based on international standards EN 300 330 and EN 303 417. These tests include:
✔ Frequency Measurement – Ensures the device operates in the permitted spectrum.
✔ Field Strength Measurement – Performed at a distance of 10 meters to evaluate radiation levels.
✔ Unwanted Emission Test – Ensures there is no excessive electromagnetic interference.
✔ Power Efficiency Evaluation – Measures how optimally the power transmitted to the receiving device is.
Benefits of Complying with KEPMEN Regulation 46/2025
By complying with this new standard, WPT device manufacturers and users can reap a variety of benefits:
- Guaranteed Legality – Devices are easier to get a distribution permit from DJID.
- Better Safety – Avoids the risk of excessive exposure to electromagnetic fields.
- Optimal Performance – More efficient power usage and minimal disruption.
- Consumer Trust – Certified products are more trusted in the market.
Conclusion
With the enactment of KEPMEN 46 of 2025, regulations on Wireless Power Transmission (WPT) devices in Indonesia are now stricter to ensure the safety and efficiency of their use. If you are a WPT manufacturer or distributor, make sure that your device meets this new standard in order to be legally and safely marketed.
