750 kva single phase to three phase transformer
You’ve got single-phase on site, but your equipment—coolers, compressors, control panels—needs three-phase to even start. We build 750 kVA transformers that make that possible, without touching your utility setup.
This is not a phase converter. It’s a full-duty, dry-type transformer—UL/CE certified, air-cooled, custom-wound to match your input and output. 240V to 480V? Generator-fed? No problem. We ship tested and ready to run.
Send us your spec—we’ll build the transformer your site actually needs.
Photovoltaics
One of our clients was building out solar-powered agri hubs across 30 villages in India. Every location had single-phase supply, but the equipment—cold rooms, grain milling, irrigation—needed three-phase. He’d tried other vendors, but the wiring setups didn’t match and the techs on site kept refusing to install them after two sites.
He asked us, “Can you do 30 units with consistent specs but customized outputs?”
We said yes—and delivered 30 750 kVA single phase to three phase dry-type transformers, all labeled, matched to inverter specs, and pre-wired the same way.
The site guys told him: “This goes in easier than the AC box.”
What he told us later: “You weren’t here, but you clearly thought like someone who was.”
Energy Storage
We had a commercial storage integrator in Malaysia reach out. Their setup was solar + battery + diesel backup, and the inverter was only giving them single-phase output. The PCS was fine, but the whole cooling system and control cabinet needed three-phase. They’d tried a converter—burned two fans in a week and the controls kept glitching.
We didn’t pitch a solution right away. First thing we asked: “How stable is your power?” He said voltage fluctuates a bit, but there’s plenty of load. That’s when we recommended going with a dry-type unit. We built a 750 kVA single phase to three phase transformer with Class H insulation and thermal sensors. It was up and running in under an hour—fans, controls, meters—all smooth.
What surprised him most? “We thought we needed a second inverter—this one transformer took care of everything.”
Wind-to-Hydrogen
A client working on a wind-hydrogen pilot in northern France called us up. The turbines were putting out single-phase AC. The electrolyzer had its own inverter, but the pumps, chillers, and PLCs needed a stable three-phase feed.
He didn’t want to reroute the whole system, just asked: “Can you drop something in behind the stack?”
We built a 750 kVA dry-type unit, IP54-rated, installed right between the DC bus and the load panel. It ran through two months of variable conditions without a single voltage dip.
What he told us after testing: “This little box did more for system stability than our main switchgear.”
Healthcare
A modular medical center in East Africa had a backup generator—single-phase only. Enough for lights and fans, but not for the HVAC, sterilizers, or elevator they needed during surgery hours.
We didn’t pitch specs. We just asked: “Is the generator stable enough for load?”
He said yes, so we built a 750 kVA single phase to three phase transformer with temp sensors, Class H rating, and a mobile rack mount. We shipped it pre-wired and labeled. They sent us one line after installation:
“Everything else had issues. This was the only part we didn’t have to redo.”
Data Center
A telecom client in the US needed to expand an edge site in a remote area. Only single-phase power was available. But the UPS, battery cooling, and control panels all needed three-phase. No way to bring in new utility lines, and local permits? Forget it.
We just asked: “Your cooling—does it need to run 24/7?” He said yes. We told him he had one choice: dry-type.
We built a 750 kVA transformer, tall enclosure, side venting, low noise. Weather-protected, fit right into their rack zone.
His team’s verdict: “This was the least stressful part of the entire power setup.”

Real Power. Real Loads. Real Conversion.
You’re running into this problem more often: the site has single-phase power, but your equipment requires three-phase—and you don’t have time or budget to rewire your whole facility. That’s where we come in.
We build all types:
From the straightforward single phase to 3 phase transformer, to specific requests like a 240v single phase to 208v 3 phase transformer or a 220v single phase to 3 phase transformer for rural HVAC systems.
Need higher voltage? We’ve made 240 single phase to 480 3 phase step up transformer units for well pumps and grain dryers.
Yes—we do the 240v single phase to 480v 3 phase step up transformer for U.S. off-grid applications, too.
Our engineers help you pick between a single phase to 3 phase step up transformer, a single phase to 3 phase transformer converter, or a full single phase to 3 phase converter transformer—depending on your load type, source stability, and install space.
We’ve supported OEMs looking for 1 to 3 phase transformers with compact builds, and helped contractors convert single phase to 3 phase transformer setups in critical install windows. Whether you need a 1 phase to 3 phase transformer converter, or you’re using single phase transformers to create 3 phase systems, we’ll walk you through it.
And yes—if you’re doing retrofits, we even build the opposite: step down transformer 3 phase to single phase units when needed.
Bottom line? You tell us your voltage and your load—we’ll ship the transformer single phase to 3 phase system that actually fits your job.
Absolutely. We’ve built single phase to 3 phase transformers up to 1000 kVA for compressors, cooling systems, and even irrigation pumps. These aren’t converters—they’re full-duty, continuous-run transformers designed for real-world work.
Great question. A single phase to 3 phase converter transformer typically integrates both the voltage transformation and phase balancing in one unit, while a single phase to 3 phase transformer converter may rely on additional electronics. For mission-critical loads, we recommend transformer-based solutions.
Yes, very common. A 240v single phase to 208v 3 phase transformer is often used in U.S. telecom and HVAC upgrades. We also supply 220v single phase to 3 phase transformer builds for international applications where 220V is standard.
Definitely. If you’re already using single phase transformers to create 3 phase systems, we can match your tap configuration, terminal layout, and protection class. We’ve helped clients expand setups using a 1 to 3 phase transformer or 1 phase to 3 phase transformer converter with consistent design.
Yes. While most of our projects involve converting single to three-phase, we also manufacture step down transformer 3 phase to single phase units for sites where high-voltage gear feeds a single-phase load—like residential branches, isolated panels, or dedicated single-load gear.
