Nidec unveils NIR3.0 prototype: 3.2 MW, 800 VDC-compatible in-row CDU
What changed
Nidec presented the NIR3.0, a prototype in-row CDU rated at 3.2 MW and described as compatible with 800 VDC power. It was shown at OCP Global Summit 2026 and Nidec targets mass production in the first half of 2027.
Why it matters Editorial analysis
This is a prototype, not a shipping product. Its pairing with 800 VDC reflects how rack power and cooling are being designed together for next-generation AI racks. Buyers planning 2027 builds should separate prototype announcements from products with a confirmed order date.
Questions a buyer should ask
- What are the rating conditions for 3.2 MW?
- What does 800 VDC compatibility mean in practice for the CDU's own pumps and controls?
- When will the unit be orderable, and with which certifications?
