Fuses are never supplied internally & without them severe damage or even fire can occur in the event of a module failure. A slow fuse with a rating of 2x the Iin max. is recommended. All specifications are typical, 25°C ambient with nominal input voltage and under full output load conditions, unless otherwise stated. These converters operate without any external components. However in low noise applications, it is recommended to use a low ESR capacitor across the input or output pins. Conducted noise filtering to EN 55022-B, VDE0871-B may be accomplished by putting an external filter. For more information, please consult the factory.
