SAFETY and EMC
Input Fusing and Safety Considerations
This HBR series converters have no internal fuse. In order to achieve maximum safety and system protection, always use an input line fuse. We
recommended a 5A time delay fuse. It is recommended that the circuit have a transient voltage suppressor diode (TVS) across the input terminal to
protect the unit against surge or spike voltage and input reverse voltage as shown below:
