Conclusion

Even with a short-circuit-protected power supply, there are applications where installing DC circuit breakers or fuses on the output is beneficial for extra protection.
However, these components, as do any long supply cables, include a voltage drop. To compensate for these drops, the front panel output voltage trim can be used.
When using an external circuit breaker or fuse, it is important that the power supply can deliver a short-term overcurrent without going into immediate short circuit protection, ensuring that the overcurrent protection devices are properly activated. The RACPRO1 series features a 250 percent / 20 milliseconds easy fuse tripping current.
