The most demanding load a distribution transformer will meet: 100% electronic, continuous, and intolerant of interruption.

Switch-mode supplies draw non-sinusoidal current: the RMS value understates the real heating. A K-rated design oversizes the windings thermally rather than simply adding kVA.
N+1 architectures run transformers at roughly half load, 24/7. Load losses drop, but no-load losses run permanently, which is why going beyond the Tier 2 floor usually pays back here.
No liquid indoors: cast-resin class F1 is the reference, ester the alternative where a liquid-filled unit is acceptable to your fire strategy.
Facilities teams expect winding temperature and status over RS485 / Modbus for DCIM integration.
| Parameter | Our approach |
|---|---|
| Technology | Cast resin (F1) or ester-filled, per your fire strategy |
| K-factor | K4 – K13 depending on the measured or estimated harmonic spectrum |
| Losses | Tier 2 floor; reduced-loss designs quoted where TCO justifies |
| Monitoring | Temperature control unit, RS485 / Modbus output on request |
| Delivered lead time | 15 to 18 weeks, production + shipping |
Indicative approach, the final specification follows your requirement, confirmed at quotation.

Because converter harmonics create eddy-current losses the RMS current doesn't reveal. Without thermal oversizing the windings run hotter than designed and the insulation ages faster, a cheap fix at design time, an expensive one afterwards.
Cast resin (F1) is the default indoors: no liquid at all. Ester is a valid route where your fire strategy accepts a liquid-filled unit and you want the cooling and overload behaviour of an immersed design.
On a site running continuously at partial load, no-load losses are permanent, over a 20–30 year life they usually outweigh the purchase premium. We quote both so the calculation is yours to make.
France's grid is bracing for a wave of data centers: RTE has already allocated on the order of 14 GW of connection rights to these projects, for a consumption that could reach 15–20 TWh/year by 2030. These rights signal a project pipeline, not yet confirmed load, but they are already pulling equipment demand and stretching lead times.
