Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
First, VR NVL72 rack with an HVDC power rack running at 800VDC (Nvidia Spec) or +/-400VDC (OCP Spec). Since the VR NVL72 rack busbar is still running at 50V and the compute tray can only take in 50V, the 800VDC from the power rack cannot be directly delivered to the busbar. There would still be DC-DC power shelves in the VR NVL72 rack. The DC-DC power shelves will step down the voltage of the current from 800VDC to 50VDC as demonstrated below.
Context After
② Atomic Claim
在第一個 HVDC power-rack deployment scenario 中，VR NVL72 rack 的 busbar 仍運行於 50V。

}④ Canonical Entity Mapping
- 此
CLAIM_ONLYrevision 沒有 canonical Entity mapping。
⑤ V2 Draft（需要修正時直接編輯）
Inline repair
只編輯以下三個 Draft 區塊。完成後將
review_action設為REQUEST_REPAIR，再手動執行 Repair Preview。
執行腳本前，Draft 不會寫入 Claim Store 或 Graph。

}⑥ Human Review
請在 Properties 逐項確認：
- 原文 → Atomic Claim 是否忠實
- Atomic Claim → Semantic Frame 是否忠實
- Canonical Entity mapping 是否正確
- Epistemic mode 是否保留原文語氣
