UL standard targets induction power transmitters

UL 2738 applies to induction power transmitters, such as wireless battery chargers, employing magnetic induction coils that transmit energy to receiving coils in low-energy devices, such as mobile phones, portable media players and global positioning devices.

The new requirements will not apply to these products powered by the induction transmitters or receivers.

The proposed UL requirements will apply to: induction power transmitters intended to be supplied by a branch circuit of 600V or less; induction receivers intended for use with specific induction power transmitters; and induction receivers intended for use with induction power transmitters conforming to industry-accepted interoperability specifications.

Before becoming a standard, these requirements will undergo a comprehensive review process by a global Standards Technical Panel (STP), open to product manufacturers, supply chain personnel, government representatives, consumers and those responsible for enforcing the requirements of codes or standards.
