Contactless power supply module
BWS Series
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.
