200kva 3 phase 208 to 480 transformer
For scalable upgrades from building power to industrial voltage.
This transformer bridges 208V commercial power and 480V industrial loads—exactly what contractors and integrators need when retrofitting older facilities or adding high-voltage equipment. Whether it’s HVAC, pumping, or control gear, 200kVA is the sweet spot for site-level upgrades.
We lock down your spec: dry-type, UL-listed, Delta-Wye or Delta-Delta as needed. Every unit is tested, matched, and labeled the same—so your crew installs 5 or 50 units without second-guessing anything.
Distributors, modular OEMs, and retrofit specialists trust Shinenergy for one reason: we don’t just ship transformers. We deliver consistency you can build around.
Solar Project: Rooftop Commercial PV Tie-In | Location: Arizona, USA
A commercial solar EPC needed to elevate 208V 3-phase inverter output to 480V to connect to a shopping mall’s main switchboard. Our 200kVA transformers were installed between the inverter cluster and the building’s electrical room.
“Using the same unit across five rooftops saved us days in design. No surprises at the site.”
Energy Storage Project: Mobile BESS Units | Location: Texas, USA
A containerized battery integrator supplied a fleet of mobile units using 208V PCS outputs. Their cooling systems and grid-interactive components required 480V. We delivered 30 dry-type 200kVA transformers, bolted inside each unit’s power bay.
“The 208 to 480 spec matched exactly. Labeling, layout, and docs were identical across all.”
Data Center Project: Edge Power Modules | Location: Amsterdam, Netherlands
A European integrator was upgrading edge nodes with 208V 3-phase local service but needed 480V to run new UPS and CRAC units. Our step-up transformers were mounted next to rack-level power panels across 12 micro-sites.
“We didn’t touch the wiring layout—every transformer fit as-is. That’s what makes scaling easy.”
Wind & Hydrogen Project: Remote Hydrogen Skids | Location: Alberta, Canada
A hydrogen startup powered its skids from 208V turbine output but needed 480V for electrolyzer control systems. Our units were floor-mounted in weather-sealed enclosures inside each trailer.
“We didn’t need tuning. Voltage was stable even under gusty conditions.”
Medical Project: Private Lab Retrofit | Location: Manchester, UK
A UK facilities contractor retrofitting lab facilities needed to convert 208V supply to 480V for autoclaves and analyzers. Our 200kVA transformers were installed in utility closets, directly between the main panel and new load banks.
“The inspector liked that we used the same spec across all sites—kept documentation simple.”

When to Use a 208 to 480V 3 Phase Step-Up Transformer
Not every site starts with 480V service. In many North American buildings—especially older ones—208V 3-phase is all that’s available. But new loads like VFDs, large HVAC systems, or imported machinery often require 480V.
That’s where a step up transformer 208 to 480 3 phase comes in. It’s not just about voltage—it’s about compatibility, wiring clarity, and ease of deployment. The key is standardization. We provide dry-type transformers with matched terminal layout, Wye or Delta configurations, and clear labeling—so contractors don’t second-guess every install.
You’ll often see this in modular equipment skids, electrical room upgrades, or fleet-based energy systems. For example, a facility rolling out 20 UPS units across five buildings isn’t looking for “a transformer”—they want 20 identical, compliant, pre-tested units that just work.
Shinenergy delivers exactly that. With fast turnaround, batch consistency, and documentation designed for field teams, you don’t just step up the voltage—you step up the reliability of your whole deployment.
It increases voltage from a standard 208V 3-phase supply to 480V 3-phase—commonly required when your facility is wired for commercial loads but your equipment (motors, HVAC, UPS) needs higher voltage input.
Yes. Every unit ships with a detailed wiring diagram, showing both Delta and Wye options. We also include terminal markings and grounding guidance to speed up installation for contractors.
A 208 to 480 step-up transformer is used for major voltage elevation. A buck-boost transformer handles fine adjustments—usually under 50V. They’re not interchangeable. Use step-up models when you’re powering 480V-rated loads from 208V mains.
Technically yes—if the transformer is bi-directional and not center-tapped. But reverse use may affect impedance, efficiency, and labeling clarity. We recommend ordering it as a step-up to avoid confusion and ensure proper tap settings.
Depends on your load. 75 kVA is common for panel-level upgrades or powering a few HVAC units. For full-building applications or motor-heavy loads, 150–300 kVA is typical. We can help you size the unit based on actual amperage and duty cycle.
