200kva 3 phase 240 to 480 step up transformer
When your facility runs on 240V but your equipment demands 480V—this is the cleanest way to bridge that gap.
Whether you’re upgrading HVAC systems, retrofitting industrial tools, or building modular power skids, this 200kVA step-up transformer takes 240V 3-phase input and delivers stable 480V output—no rewiring the grid, no design overhauls.
Used by contractors, integrators, and equipment builders who need repeatable installs, we deliver each unit dry-type, UL-listed, and spec-locked—so whether you’re deploying 5 or 50, the layout, labels, and performance are always the same.
Solar Project: Rooftop PV Integration | Location: Fresno, California, USA
A commercial PV contractor needed to integrate 240V 3-phase inverter output into an existing 480V service panel across six big-box retail sites. Our 200kVA step-up transformers were installed between combiner boxes and switchboards.
“We used the same setup on every site. No layout changes, no surprises—just plug and align.”
Energy Storage Project: Grid-Connected BESS Skids | Location: Ontario, Canada
A BESS integrator was building mobile container systems using 240V PCS output. Their grid tie-in required 480V. Each 20-ft skid embedded a 200kVA step-up transformer mounted next to the battery inverter.
“It fits into our prefab workflow. We’ve shipped 40+ units with identical wiring and specs.”
Data Center Project: Edge Computing Nodes | Location: Dublin, Ireland
A European data integrator deployed edge pods across Ireland, powered by 240V 3-phase service. But the UPS and in-row cooling units required 480V. Our transformers were rack-adjacent, inside power bays.
“We didn’t modify any cabinets—just dropped in the same 200kVA unit each time.”
Wind & Hydrogen Project: Skid-Mounted Hydrogen Test Units | Location: Colorado, USA
A hydrogen tech firm used 240V from small wind turbines to power their trailer-based electrolysis systems. Control circuits and pumps required 480V. Our floor-mounted step-up units were placed at the skid’s power intake.
“They stayed stable even with variable wind. Repeatable, reliable—we just kept ordering more.”
Medical Project: Lab Modernization Program | Location: Bavaria, Germany
A facilities contractor was upgrading diagnostic labs with new analyzers and sterilizers that needed 480V. However, the utility feed was 240V 3-phase. Our wall-mounted 200kVA units sat between main breakers and load cabinets in each facility.
“We standardized across 18 sites. The inspector signed off fast because everything matched.”

Choosing the Right 240V to 480V 3 Phase Step-Up Transformer
One of the most common problems engineers face in retrofit or modular design is this: your building or panel only offers 240V, but your equipment needs 480V. Rewiring the entire infrastructure is costly and often impractical—so you step up.
A step up transformer 240 to 480 3 phase provides the simplest solution. It bridges commercial or legacy 240V 3-phase power with modern 480V equipment demands. But not all installations are alike. Some clients need a 3 phase 240 to 480 step up transformer that supports Delta output for motor loads; others require a Wye secondary to stabilize downstream voltage for mixed-use panels.
And capacity matters. A 3 phase step up transformer 240 to 480 75 kVA may work for a few compressors or a control rack. But when you’re powering multiple HVAC systems or a high-load machine cluster, we often recommend stepping up to 150 or 200 kVA models for safety margin and thermal efficiency.
At Shinenergy, we don’t just ship transformers—we ask the right questions to get you the right match. Need the wiring diagram? It’s in the box. Need 12 more units next month? You’ll get the same label, same spec, same wiring.
It’s used to convert 240V 3-phase input—commonly found in older or commercial power systems—into 480V 3-phase output for motors, HVAC units, UPS systems, or industrial controls. It allows you to power high-voltage equipment without upgrading your utility feed.
Not directly. A transformer doesn’t change phase types—it only adjusts voltage. If you’re going from 240V single-phase to 480V 3-phase, you’ll need both a phase converter and a step-up transformer. Shinenergy offers pre-matched systems for this type of upgrade.
No difference in function—just variation in how customers phrase it. Both refer to the same product: a three-phase transformer that steps up from 240V to 480V.
Yes. All units come with Delta and Wye diagrams, terminal labeling, and installation instructions—available in PDF format. We also offer versions customized for North American NEC requirements and IEC standards in Europe.
It depends on your load. 75 kVA is ideal for powering small control systems, multiple 480V panels, or individual machines. For full-facility applications, 150–300 kVA is more common. We help customers size based on continuous load and surge conditions.
