1000 kva 3 phase step down transformer
You’ve got equipment that needs 460V, but the supply is 480V. Or maybe you’ve only got 208V, and your machine needs 240V to work right. That mismatch? It’s exactly what a 3 phase buck boost transformer is built for. No need to redesign the system—just clean up the voltage where it matters.
We build low-voltage, three-phase buck boost units for commercial and light industrial use. Typical loads include HVAC motors, lighting banks, CNC machines, or even server rooms. They’re compact, air-cooled, and easy to mount. Available in ratings from 3 to 75 kVA—sized to fix the problem, not overcomplicate it.
Not sure if you need to step up or step down? Send us your line voltage and equipment nameplate—we’ll confirm what direction you need and quote the right unit.
Let us fix the mismatch, not your whole setup.
Photovoltaics – California, USA
A solar-plus-storage developer in California was working on a commercial project with 600V inverter output. But the site needed 208Y/120V for office panels, exhaust fans, and lighting. Space was tight—no room for a secondary switchgear room.
He asked: “Can you get us a transformer that drops 600V to 208, and fits next to the inverter?”
We supplied a 1000 kVA 3 phase step down transformer, sealed housing, front-facing terminals, custom mounting holes for slab anchoring. The crew dropped it in, wired it, and didn’t have to trench back to the building panel.
The client later said: “This one transformer saved us 120 feet of conduit—and two days of trenching.”
Energy Storage – Houston, Texas, USA
In a Houston-area industrial BESS project, the PCS system was pushing 480V, but the building’s internal loads—HVAC, fire pumps, lighting—were all 208V. The original plan used multiple small transformers, but field contractors pushed back.
The PM asked: “Can we just get one big transformer to drop everything in one go?”
We shipped a 1000 kVA 3 phase step down unit, 480 to 208Y/120V, dry-type, open ventilated. It landed next to the PCS and handled the entire secondary load without a single call-back.
The project lead said: “It’s the only part of the electrical plan that didn’t go back for revision.”
Data Center – Ontario, Canada
A data center team near Toronto had just expanded a cold aisle zone, but their new gear needed 240V single-phase. Their power bus? Three-phase 480V—and the raised floor was already sealed.
“Ceiling’s full. Wall’s full. We just need something to go under the floor.”
We sent a 1000 kVA 3 phase step down transformer, 480V to 240V, low-profile body, front-access terminals, and floor rollers. They rolled it under the aisle and landed it within half a day—no cutting, no conduits rerouted.
Their tech said: “That transformer was the cleanest part of our Phase 2.”
Wind-to-Hydrogen – Iowa, USA
A hydrogen pilot site in Iowa was using wind turbines to power compressors and chillers. Turbine output was 600V, but the load panel required 240V. They’d tried two soft-down solutions—none stable.
“We want this off our troubleshooting list. Can you just give us a dry-type transformer?”
We built and delivered a 1000 kVA 3 phase step down transformer, 600V to 240V, sealed, vibration-damped base, thermally coated. It sat right between the turbine output and the control cabinet. The compressors ran clean for the first time.
The site lead told us: “This was the only thing the compressor guys didn’t argue about.”
Healthcare – Cape Town, South Africa
A private rehab hospital in Cape Town was expanding. Their new floor had elevators, rehab treadmills, and door motors—all running on 208V three-phase. But the new service feed was 480V.
Their facilities head said: “We don’t need options. We need a transformer that fits—and works.”
We shipped a 1000 kVA 3 phase step down transformer, 480 to 208Y/120V, Class H insulation, front terminals, and compact enclosure. It was installed in the electrical shaft—no wall changes, no extra structure.
The hospital director said: “The lights came on. That’s all I needed to hear.”

Your Load Needs the Right Voltage. We Make the Drop.
You’ve got 480V on site, but your gear runs at 240V or 208V? That’s what a 3 phase step down transformer is for. Whether it’s a step down transformer 240 to 208 3 phase, or a 3 phase 240V to 208V step down transformer, we build exactly what your system needs—no converters, no questions.
Our dry-type units cover common voltages like 480 to 240, 480 to 208, 380V to 220V, and even niche cases like 460 to 230 3 phase step down transformer. Need a step down transformer 3 phase to single phase for a mixed load panel? Done. Need to figure out the kVA size? Our 3 phase step down transformer calculator and team will get you there.
Each transformer comes with a clear wiring diagram—whether you’re looking for 3 phase step down transformer wiring, a 240 to 208 3 phase wiring diagram, or even just wondering how to wire a 3 phase step down transformer, we’ve got you covered.
It’s not just about voltage—it’s about getting your system up and running with the power it expects.
📩 Send us your voltage pair and load amps. We’ll send you the transformer that makes it work.
None. It’s the same thing—just written two ways. A 480V 3 phase step down transformer typically converts to 240V, 208V, or 120/208Y. What matters is your load voltage and how your panel is wired.
Yes—and we’ve done it hundreds of times. A 240 to 208 3 phase step down transformer is ideal for systems running on legacy 240V but needing to serve modern 208V loads. We offer both 3 phase 240v to 208v step down transformer and reverse setups.
Absolutely. Every unit comes with a labeled 3 phase step down transformer wiring diagram. Whether you’re installing a step-down transformer 240 to 208 3 phase or a step down transformer 3 phase to single phase, we’ll show you the exact tap points.
We’ll do it for you—but if you want to calculate it yourself, use our 3 phase step down transformer calculator. Just input your line voltage, output voltage, and load amps—we’ll give you the right kVA rating, whether it’s 5kVA or 1000kVA.
No problem. A step down transformer 380v to 220v 3 phase is common in export systems, especially in Asia and the Middle East. We also provide clear specs and 380v to 220v 3 phase price estimates based on power rating and enclosure type.
