I bought a nominally 30A SMPS like [this one](https://rads.stackoverflow.com/amzn/click/com/B07TZ2TRRB) to use for powering 5 strings of fifty 5v ws2811 LED pixels:

The diagram seems to imply that both "-V" terminals are equivalent, and both "+V" terminals are equivalent... but the PSU itself came with no documentation whatsoever.

Can I safely assume that both -V and +V terminals are, in fact, identical, equivalent, and freely-interchangeable if a multimeter indicates 0-ohm resistance (with no power applied to L+N) between the two -V terminals and between the two +V terminals, and +v1 to -v1, +v1 to -v2, +v2 to -v1, and +v2 to -v2 all show "+5v"? Or are there any other potential "gotcha" scenarios lurking that wouldn't necessarily be obvious to someone who's never used PSUs of this type before (as opposed to, "generic black brick with power cord on one end, and DC barrel jack on the other")?

(note: I know I need to use a fuse, and I'm planning to inject power between every string of 50 to compensate for voltage drop... I'm just feeling unsure about the reason *why* a value-engineered power supply that probably cut every conceivable corner nevertheless included TWO + and - terminals instead of a single pair, and contemplating the possibility that there might be a subtle *reason* I really need to be aware of & won't necessarily be happy about).
