1． Application

This specification applies to the contactless power supply module BWS50-

28S1R5.

2． Overview

BWS50-28S1R5 is a module designed for power transmission using contactless power transfer

technology. The module consists from 3 modules: PFC module, power transmitting module and power

receiving module.

Although assumed usage of this product is charging of lithium ion batteries with capacity of 3~10 Ah, it

can also be used as power supply with fixed voltage and current. In this case confirm the operation mode

before using the module.
