Power Supply and Distribution System

4.1 Overview

The power supply and distribution system has two power distribution
architectures: N+X and 2N. Two UPSs are configured in 2N mode, and one UPS is
configured in N+X mode.

The power supply and distribution system provides power separately for power
and IT equipment, and supports air cooled smart cooling products, fire
extinguishing devices, lights, ECC800-Pro, and other auxiliary devices inside the
pre-fab. module.
The power supply and distribution system mainly consists of the integrated UPS,
power PDB, AC actuator, AC PDB, and rPDU.

In the N+X scenario, the UPS supports two ATS inputs and a maximum power
capacity of 60 kVA (modules in 2+1 redundancy), providing a backup time of
15 minutes.
In the 2N scenario, two UPSs provide two MCCB inputs and support a
maximum power capacity of 60 kVA (modules in 2+0 redundancy), meeting
the system backup time of 20 minutes.
The battery system uses lithium batteries. Compared with lead-acid batteries,
lithium batteries have more cycles, longer service life, and better discharge
capability in short-term backup power scenarios.
Lithium batteries are installed in the SmartLi lithium battery cabinet. In both
N+X and 2N scenarios, the lithium battery cabinet uses half-capacity
configuration (eight battery modules in one string).
