Datacenter
UPS (Uninterruptible Power Supply)
A UPS provides backup power during outages, ensuring continuous datacenter operation.
Definition
An Uninterruptible Power Supply (UPS) is a critical datacenter component that provides emergency power when the main power source fails. UPS systems use batteries (for short-term bridge) and flywheels (for instant switchover) to maintain power until generators start. Modern datacenter UPS systems: (1) Double-conversion — clean power with zero transfer time, (2) Efficiency 97%+, (3) Modular design for scalability, (4) Lithium-ion batteries (10-year life vs 5 for VRLA). Harch Corp uses 2N UPS redundancy (dual UPS systems) for 99.99% power availability.
