500 kva single phase to 3 phase transformer
When three-phase power isn’t available—but your equipment still needs it.
You’ve got single-phase power, but your motors, HVAC, or control panels demand three-phase. That’s where our 500 kva single phase to 3 phase transformer
steps in—built for real loads, real sites, and long runtimes.
We design dry-type, air-cooled units with the insulation, voltage matching, and protection your application requires—UL listed, quiet-running, and available in both copper and aluminum windings.
Input/output voltages and connection layout? Customizable. Installation conditions? We’ve handled indoor, outdoor, and tight enclosures across industries.
No converters. No grid upgrade. Just clean, stable 3-phase from the supply you already have.

Energy Storage – Bridging the Power Mismatch
A storage EPC in Colombia came to us during system testing—everything on site was running single-phase from solar-charged inverters, but the PCS cooling fans and relay cabinets needed clean three-phase. They’d tried a rotary converter. It buzzed and tripped all week.
We delivered a 500 kVA dry-type transformer, tuned for their specific voltage ratio and site frequency. Installed in two hours. Passed thermal test.
The site manager said: “That was the only thing we didn’t have to tweak post-commissioning.”
Solar – Serving 3-Phase Loads in a Single-Phase Architecture
In rural Italy, a mid-sized agrivoltaic farm had a solar-fed single-phase supply powering offices and equipment. Problem was, their new cold storage unit required a three-phase input. The supplier wouldn’t warranty it on phase conversion.
We matched their inverter output to a 500 kVA single-to-three transformer, with IP23 protection for their dusty install zone.
“It let us keep the solar footprint untouched—and plug in the cooler same week.”


Healthcare – Backup Systems That Can’t Be Fragile
A private clinic in South Africa added a mobile MRI unit—but the entire facility ran on a single-phase generator during outages. The scanner’s cooling required balanced three-phase power.
We supplied a low-noise, fully enclosed 500 kVA transformer, rated for hospital environments. It shipped pre-terminated, passed safety checks on arrival, and tied into their backup panel with no delay.
Their facilities lead told us: “This unit did what the generator couldn’t—stabilize our voltage where it matters most.”
Data Center – Solving Load Imbalance at the Edge
A telecom company was building edge sites in the Midwest US where utility feeds were limited to single-phase. But their UPS, in-row cooling, and switchgear were all 3-phase units.
We helped them redesign the power section with 500 kVA single-phase input transformers to convert and balance the loads. No cabinet changes. No additional permitting.
“This gave us enterprise-grade distribution without reengineering the site.”


Wind-to-Hydrogen – Supporting the System Behind the Stack
In Denmark, a hydrogen pilot line used small wind turbines that delivered single-phase AC. While the electrolyzers had dedicated inverters, the water treatment and compression system expected three-phase input.
Our transformer sat between the energy buffer and utility panel, delivering stable 3-phase output even under variable input conditions.
“It’s the quiet fix that made the rest of the system run like it should.”

A single phase to 3 phase transformer is designed to generate balanced three-phase power from a single-phase source. This is common in rural areas, solar-powered buildings, or industrial zones with limited grid capacity.
Yes, if your equipment requires 208V three-phase input, a 240v single phase to 208v 3 phase transformer can convert your available single-phase line into a compatible three-phase supply—especially useful in HVAC, refrigeration, and automation.
A single phase to 3 phase step up transformer increases voltage and converts phase, while a single phase to 3 phase transformer converter also mimics phase shift electronically. For stable, load-bearing power, transformers are the preferred long-term solution.
Yes. A 1 phase to 3 phase transformer, 1 to 3 phase transformer, or transformer 1 phase to 3 phase all refer to the same function: converting single-phase input to usable three-phase output, typically for motors or mixed load applications.
Yes—many setups involve using single phase transformers to create 3 phase system arrangements. This often includes three identical single-phase units configured in a delta or wye system to simulate a full 3-phase supply.
We also offer complete packages like the 240 single phase to 480 3 phase transformer or 220v single phase to 3 phase transformer, depending on the application.
