750 kva transformer step up transformer 208 to 480 3 phase
If you’ve got 240V power but need 480V to run your load, this is the transformer for it.
Shinenergy’s 750 kVA dry-type step-up transformer boosts 240V three-phase to 480V cleanly and reliably. Built for data centers, generator backup, and industrial retrofits.
We offer copper or aluminum windings, Class F or H insulation, and top or side cable access. Each unit ships pre-tested, labeled, and with wiring diagrams for fast install.
UL / CE certification? No problem. Tell us your specs—we’ll get it built, packed, and moving.
Photovoltaics – San Diego, California, USA
In a commercial PV deployment in San Diego, the client used 240V three-phase inverters but needed to tie into a 480V facility main line. Changing the inverter setup wasn’t an option—they needed a stable, utility-accepted voltage lift.
We supplied a 750 kVA dry-type step-up transformer (240V to 480V) with copper windings and IP23 enclosure. It was wired directly from the inverter output to the panel. Grid sync passed on the first test—no rework needed.
Energy Storage – Madrid, Spain
A BESS integrator in Madrid required a 240V PCS output to be stepped up to 480V for EV fast charging. With limited floor space, they requested a vertical unit, bottom cable entry, and a fast delivery schedule.
Shinenergy delivered a 750 kVA three-phase transformer, aluminum-wound, Class H insulated, and fitted with a custom terminal layout. The install crew completed commissioning in half a day.
Data Center – Toronto, Canada
A Toronto-based edge data center operator kept their legacy 240V UPS bus but upgraded new rooms to 480V racks. They needed clean step-up transformation without introducing power quality issues.
We provided a 750 kVA dry-type transformer, 240V to 480V, with a low-noise core and top-exit terminals. Housed in a ventilated cabinet beside the UPS room, the unit passed UL inspection and was added to their standard deployment kit.
Wind-to-Hydrogen – Bremen, Germany
At a wind-to-hydrogen demo site near Bremen, wind turbines delivered 240V via VFDs, but the electrolyzer control system ran at 480V. The client required voltage conversion, thermal stability, and system isolation.
We built a 750 kVA three-phase dry transformer, epoxy sealed, IP54 rated, with busbar-compatible terminations. It was installed between the inverter bank and the H₂ system—up and running in one week.
Medical – Chicago, Illinois, USA
During a hospital retrofit in Chicago, new surgical support systems came with 480V requirements, while only 240V was available at the site’s distribution board. The facility could not afford downtime.
We delivered a 750 kVA dry-type step-up transformer with copper windings, Class F insulation, and a front-access enclosure. It was embedded in the room’s power cabinet and commissioned with full documentation and UL labeling included.

⚡ Got 240V, Need 480V? Here’s Your Fastest Fix.
Whether it’s a legacy panel, a generator output, or a local utility feed—240V three-phase is everywhere. But your equipment, most likely, needs 480V. That’s where our step up transformer 240v to 480v 3 phase comes in.
We build dry-type transformers sized for real-world jobs—rooftop solar, machine upgrades, even panel exports. From 240v 3 phase to 480v 3 phase step up transformers to single-phase conversions, we match every unit to your voltage, load, and layout. Top or side terminals? Aluminum or copper? We’ve done them all.
Every unit comes with a clear 240v to 480v wiring diagram, labeled taps, and optional UL or CE certification. You get clean voltage. We handle the rest.
Typically when your local utility or generator gives you 240V, but your equipment—HVAC units, control panels, or export systems—requires 480V. The transformer bridges that gap without redesigning the whole system.
Yes. Our dry-type 240V to 480V step-up transformers are made for indoor mechanical rooms, server spaces, or enclosed panels—ventilated or sealed, depending on your layout.
Absolutely. Many commercial PV systems operate at 240V, but utilities demand 480V tie-ins. This transformer helps you meet grid requirements without swapping inverters.
Yes, we can configure phase-converting models, but most clients use a rotary phase converter ahead of a standard 3 phase step-up transformer. Tell us your load type and we’ll advise the best match.
Of course. Every unit ships with a 240v to 480v step up transformer wiring diagram, labeled terminals, and tap instructions based on your install layout.
Common builds include 45, 75, 150, 300, and 750 kVA. If your load is outside that range, we can size a unit specifically for your application.
