Regarding system power supply selection, what are the advantages and disadvantages of the N+1 and redundant configurations? Among them, how is N in N+1 generally determined? Please, experts, share your opinions! Thank you!
Is there any friend who is familiar with this area who can introduce it to us?
I’m here to participate. Haha, the power supply we use in our setup is of the P+F N+1 type; it outputs DC24V, which then goes to the busbars and from there to each circuit breaker. I once encountered a problem where the two UPS power inputs couldn’t be in the same phase or something like that; I can’t remember exactly. In any case, as soon as the other unit was turned on, it started to smoke. Here, one circuit feeds directly through the UPS, while the other circuit is isolated by a transformer before being used. As for risks, it is said that the bus bar can pull down the entire circuit when connected to ground. For our other devices, we use Siemens 24VDC power supplies along with two redundant (Schottky) modules; one pair per cabinet. We’ve used quite a number of these, so the risk level is pretty high!
Could you send some photos or wiring diagrams so I can take a look?
Is it the P+F PS3500?
Aren’t N+1 and redundancy network types?
The system power supply also comes in an N+1 configuration!
