Frequently Asked Questions
What is a hot-swappable power module and why does it matter?
A hot-swappable power module allows you to replace the power supply while your system remains running. This eliminates costly downtime during maintenance, upgrades, or component failures — critical for 24/7 enterprise operations like surveillance systems, network aggregation, and storage infrastructure.
Is the UniFi 550W power module compatible with my CloudKey Enterprise system?
Yes. The UACC-PSU-12V-550W is specifically designed for CloudKey Enterprise, Enterprise Aggregation, Enterprise NVR, and UNAS Pro 8 systems. Its 12V DC output and 550W capacity provide stable power for these mission-critical platforms. Always verify your system's power requirements before ordering.
Can I use this 550W AC-to-DC power supply in different countries?
Absolutely. The universal AC input (100–240V) makes this 12V DC power supply suitable for global deployment. The C14 connector is standard across enterprise infrastructure, and NDAA, CE, FCC, and IC certifications ensure compliance in regulated environments.
What makes the SGCC steel enclosure important for enterprise power modules?
SGCC steel provides superior durability and electromagnetic shielding, protecting internal components from environmental stress, interference, and physical damage. This industrial-grade construction ensures long-term reliability in data centers, network closets, and demanding deployment scenarios.
