225 kva three phase to single phase transformer
Got 3-phase power coming in, but your key load runs single-phase? Our 225 kVA three phase to single phase transformer makes that shift simple—no converters, no rewiring, just steady power.
It’s dry-type, UL-listed, and built to match your specs. We support copper or aluminum windings, Class H insulation, and flexible terminal layouts—top, side, or bottom entry, whatever fits your space.
Installed in control systems, test benches, and power rooms where stable 240V or 120V single-phase is required—especially in North America and export markets with split-phase standards.
Photovoltaics – Arizona, USA
One of our EPC clients was finalizing a solar-plus-storage site in Arizona. Their inverters pushed out 480V three-phase, but the site’s weather station, motorized breakers, and metering units were all built around 240V single-phase input. They didn’t want to run separate cabling or downgrade the main line.
We supplied a 225 kVA three phase to single phase transformer, dry-type, 480V to 240V, copper windings, and side terminal box for direct mount inside the inverter pad. The install crew wired it into a shared junction frame—no added conduit, no delays.
Client feedback: “Cleanest part of the whole job. Landed, wired, worked.”
Energy Storage – Texas, USA
A BESS integrator in Texas needed to isolate single-phase control loads from a 600V three-phase PCS system. The client’s SCADA panel and battery safety controls were all rated at 120/240V single-phase, and they didn’t want those lines tied to the primary inverter supply.
We built a 225 kVA three phase to single phase transformer, with 600V input and split-phase 120/240V output. The unit was dry-type, floor-mounted, and sized to slide directly beneath the O&M platform enclosure.
After commissioning, their lead tech said: “Finally—no more converters on the control side.”
Data Center – Ontario, Canada
A colocation site outside Toronto had a legacy rack-mounted cooling system that required a full 240V single-phase feed. The building’s incoming service was 480V three-phase, and the new facility manager didn’t want to touch the existing UPS tie-in.
We provided a 225 kVA dry-type transformer, configured 480V three-phase to 240V single-phase, aluminum wound, compact format. It was placed behind the main switchboard and wired to a separate MCB.
Client summary: “It’s powering our most delicate zone, and we haven’t touched it since.”
Wind-to-Hydrogen – Scotland, UK
A hybrid wind-to-hydrogen test station in Scotland had a skid-based loadout that required clean single-phase 230V power for compressors and sensors. Their turbine output was 400V three-phase, but the control layer was completely single-phase.
We supplied a 225 kVA three phase to single phase transformer, 400V to 230V, Class H insulation, epoxy-coated for coastal humidity. The unit was mounted in a small weatherproof housing next to the hydrogen pump stack.
The customer wrote: “Stable voltage in a salty wind tunnel. Better than we expected.”
Medical – Seoul, South Korea
A hospital in Seoul was upgrading its radiology floor. The imaging workstations, data recorders, and isolation devices all operated at 240V single-phase, but the building’s feed was 415V three-phase. The architect requested a transformer that could be recessed into a floor utility bay.
We delivered a 225 kVA transformer, 415V to 240V single-phase, dry-type, low-profile design with top-exit cable access and ultra-low noise rating. It passed local inspection without adjustment.
The facility lead said: “Zero interference, and quieter than the cooling fans.”

Built to Last: How We Build 3-Phase to Single-Phase Transformers Right
When you’re supplying critical loads off a 3-phase feed, the transformer is not where you want surprises. At Shinenergy, we treat every three phase to single phase transformer like it’s going into our own switchroom.
It starts with the numbers. We don’t guess kVA—we run full three phase to single phase transformer calculations based on your actual amperage, duty cycle, and site voltage. We won’t oversell you a 300 kVA unit when 225 is right—or send you something underbuilt for startup loads.
On the floor, we keep it simple: clean coil alignment, dry-type builds with Class F or H insulation, and terminal setups that match your layout. Whether your installer calls for top-entry, bottom conduit, or a side-wired terminal box, we prep the frame accordingly. Every unit leaves with a clear, labeled wiring diagram—not just a PDF but a sticker right where your electrician needs it.
And yes, we test every unit. No skips. No batch tests. One by one, full-voltage run, checked for balance and temperature rise. What you get isn’t just a transformer—it’s something that lands, wires, and works.
Because in your world, a 240V single-phase supply isn’t optional—it’s the heartbeat of the job.
Yes, that’s one of the most common use cases. A 480 to 240 3 phase step down transformer will give you stable, balanced voltage for standard U.S. industrial loads. We’ll make sure your output delta or wye matches your panel.
They’re close, but not the same. If you’re coming from a step down transformer 380V to 220V 3 phase, you’re likely working with European or export voltage. If your gear says 208V, you’ll want a true 3 phase step down transformer 240 to 208 setup.
You can. A properly configured step down transformer 3 phase to single phase can give you both. We often tap the secondary to provide 120V or 240V single-phase alongside your 208 or 240 three-phase. Just let us know your layout.
That’s common in older industrial sites. Many motors and control systems are rated 230V, but the building service is 460V. We build 3 phase 460 to 230 transformers with copper or aluminum windings, sized for motors, panels, or mixed loads.
Always. Every unit we ship comes with a clear, labeled 3 phase step down transformer wiring diagram—whether you’re landing it into a 208Y/120 system or a 240 delta. If you’re not sure how to land it, we’ll review your config with you before it ships.
