Does R630 Power Supply have short circuit protection?

Hi there,

I am being asked by our customer that requires elaborations on the following two:

The communications equipment must have a function for blocking over-current by MCCB, fuses, etc. or a safeguard function for stopping operation of the device for internal short circuits etc.

> What mechanism does R630 use for short circuit protection?

Operation of a communications equipment with a dual-input system must be unaffected even when differences between phase, voltage, frequency, etc. of the two systems occur.

> Does R630 meet this requirement? How does R630 provide the protection?

Please let me know if you guys have a clue. Thank you!
