The simplest method is to connect a °C 25 circuit breaker to the circuit. Recommended testing and application circuit If you want to further decrease the input/output Free air convection ripple, an “LC” filtering network may be connected Plastic(UL94-V0) to the input and output ends of the DC/DC Short circuit protection* 1 MTBF circuit of these products has no protection against self-recovery fuse in series at the input end or add a 300 Cooling Overload Protection Under normal operating conditions, the output 3500 S converter, see (Figure 1).
