What Mitsubishi Electric makes for data centers
public · HQ Tokyo, Japan · mitsubishielectric.com
Within Mitsubishi Electric's broad portfolio, the data-center-relevant lines are electrical and thermal equipment: large power transformers and HV/MV/LV switchgear, UPS systems and the IGBT/SiC power modules inside them, and chillers and CRAH units sold under its Climaveneta brand. It also makes VCSEL and EML laser components used in optical transceivers, and is listed as an emerging coolant distribution unit supplier.

Where Mitsubishi Electric sits in the stack
Mitsubishi Electric's placements in this catalog cover 12 parts, from layer 3 (networking & interconnect) to layer 8 (power generation & energy supply). One of them is tagged constrained, meaning a sourced shortage rather than a long lead time. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Large power transformers (345–765 kV) & substationsconstrained — Grid-scale transformers and switchyards that step transmission voltage down to what a data center campus can use, plus the substation civil works around them.
- Lasers — The laser sources — EML, CW/DFB, and VCSEL types — that generate the light signal inside optical transceivers and co-packaged optics.
- Coolant distribution units — The unit that separates the IT-side (technology) coolant loop from the facility water loop, exchanging heat between them and pumping and filtering the technology-side flow — sized from in-rack and in-row units up to multi-megawatt facility-class units.
- Chillers & compressors — Chillers use a vapor-compression or absorption cycle, built around a compressor, to produce chilled water for the facility's cooling loop.
- CRAH / CRAC / fan walls / in-row units — CRAH, CRAC, fan-wall, and in-row units circulate conditioned air across IT equipment in air-cooled halls, using either facility chilled water (CRAH) or an internal refrigerant circuit (CRAC).
