Product Introduction
The power shelf consists of the power chassis, PSUs, and management module. The power shelf converts the AC power into stable DC power for the cabinet through the AC/DC module. The chassis supports flexible 19/21 inch rack and dual input of HVDC/AC. The PSU integrates a built-in static transfer switch (STS) unit for dual input and N+1 redundancy. Compared to traditional 2N architectures, it reduces procurement costs by 45%, increases power density by 45%, and improves efficiency by 1%. With a 3U form factor and 33 kW per cabinet, the system achieves annual energy savings of approximately 1,500 kWh.
