- Frequently Asked Questions
Why -48V DC for telecom?
-48V DC is the standard telecom power voltage, chosen for safety (below hazardous voltage) and compatibility with battery backup.
What is N+1 rectifier redundancy?
N modules carry the load and one spare provides redundancy, so a rectifier failure does not interrupt power.
