4 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
congured in 2N mode, and one UPS is
congured in N+X mode.
● 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
conguration (eight battery modules in one string).
The power supply and distribution system provides power separately for power
and IT equipment, and supports air cooled smart cooling products,
re
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.
