10kV SST
The 10kV SST (Solid State Transformer) is designed for next-generation AI data centers and dense compute infrastructure. Starting from 10kV medium-voltage access, it enables an efficient and intelligent front-end power architecture for the 800V DC platform, working together with downstream BBU, DC-DC, and PDU modules to support end-to-end power deployment from utility access to rack-level distribution.

Key Advantages
01
Supports 10kV medium-voltage grid access, helping simplify traditional multi-stage power conversion paths and enabling a shorter, more efficient front-end power architecture for AI data centers.
02
Acts as the front-end energy platform for an 800V DC power architecture, enabling unified integration with downstream BBU, DC-DC, and PDU modules for next-generation AI rack-level power systems.
03
Compared with conventional transformer and distribution schemes, SST delivers faster dynamic response and more precise energy control through a solid-state power electronics architecture, making it ideal for AI workloads with rapidly changing loads.
04
Aligned with the high-density direction of the existing product family, the 10kV SST can serve as a highly integrated power conversion node that helps reduce front-end power footprint and extend the space-efficiency advantages of the downstream high-density power platform.
05
Designed for modular deployment across different AI data center power scales, it can work together with PSU, BBU, PDU, and DC-DC modules to support capacity expansion, hierarchical distribution, and backup power integration.
06
For website positioning, the SST should be presented as a core power node with advanced monitoring, communication, and energy management capabilities, consistent with the existing product family’s support for PMBus, MODBUS/CAN, and optional PMC monitoring modules.
