UL 2738 2nd Edition, January 12, 2018 UL Standard for Safety Induction Power Transmitters and Receivers for use with Low Energy Products
More info
Description / Abstract:
These requirements apply to:
a) Induction power transmitters intended to be supplied by an internal or external power source, which is powered by a branch circuit of 600 volts or less; and
b) Induction receivers intended for use with induction power transmitters.
With regard to 1.1(b), the output from an induction receiver assembly does not exceed:
a) 60 V dc or 42.4 V ac peak; and
b) 100 VA capacity.
Exception: Greater voltage or VA limits are permitted when the combination receiver and supplied equipment comply with the applicable end-product requirements.
An induction power transmitter employs a magnetic induction coil(s) transmitting energy to a receiving coil in a device placed near the power platform.
An induction receiver is a device intended for powering a low energy product. The receiver may be an incomplete device intended for installation in or on the low energy product, or the receiver may be a complete device intended for connection to a low energy product.
An “induction battery charger” is an example of induction power transmitting and receiving equipment covered by these requirements. Examples of low energy products powered by the induction transmitter and receiver include cell phones, personal data assistants, portable media players, global positioning devices, and similar small battery powered portable devices.
These requirements do not apply to a product powered by an induction receiver. Requirements for the powered product are specified in the appropriate end-product Standard which may be supplemented by these requirements.
These requirements do not apply to a product with an integral induction receiver. Requirements for such products are specified in the appropriate end-product Standard which may be supplemented by these requirements.
These requirements do not address physiological effects, or electromagnetic compatibility with other equipment and power systems.
