100 kva 480v to 220v 3 phase transformer
Not all machines run on your building’s voltage—but that doesn’t mean you need to redesign your system. This 100 kVA transformer safely converts 480V to 220V 3-phase, making it ideal for integrating imported equipment, retrofitting old panels, or syncing with 220V-standard loads.
Built to handle industrial conditions. Dry-type, UL-listed, and fully enclosed. For OEMs and EPCs handling multiple deployments, we ensure consistent specs, fast production, and plug-in-ready connections. No guessing, no delays—just clean, reliable power.
Photovoltaic – Distributed Inverter Rooms in Southern California
In a solar farm outside Bakersfield, California, our 100 kVA 480V to 220V step-down transformers are used inside inverter rooms to provide stable auxiliary power for control PLCs and tracking motors. Since many solar monitoring units require 220V 3-phase input, this transformer bridges the gap between the plant’s 480V output and the device’s design spec—without additional wiring complexity.
Energy Storage – Containerized BESS in Northern Germany
In a battery energy storage site deployed by a European EPC firm in Schleswig-Holstein, each battery container includes a 100 kVA transformer to power 220V-based ventilation systems and cabinet heating circuits. The main input is 480V from the site’s collector bus. Our dry-type transformer ensures electrical isolation, quiet operation, and safe voltage adaptation within compact enclosures.
Data Centers – Power Distribution for Edge Server Clusters (Texas, USA)
For an edge data center project in Austin, Texas, 100 kVA units are placed downstream of the 480V building feed to serve legacy 220V three-phase PDU racks. This allows the client to maintain compatibility with older server infrastructure during phased upgrades, avoiding downtime. The transformers are mounted in overhead trays with low-noise encapsulated cores to reduce audible disturbance.
Hydrogen from Wind – Auxiliary Load Supply in Denmark
In a 10 MW wind-to-hydrogen project near Esbjerg, Denmark, Shinenergy’s 100 kVA 480V to 220V transformers are used to power valve actuators, sensor modules, and 220V metering equipment inside the electrolysis skid. These loads require stable low-voltage three-phase power, isolated from the high-voltage bus. Our transformer ensures clean output and surge protection in corrosive coastal environments.
Medical – University Lab Expansion (Chicago, USA)
During a university hospital’s lab expansion in Chicago, the engineering team used our 100 kVA transformers to step down the hospital’s 480V building power to 220V, supplying medical analyzers and climate control systems in compliance with manufacturer voltage tolerances. The transformers were wall-mounted in electrical rooms, selected for their compact footprint and UL-listed safety rating.

Choosing Between 480V to 220V Step Down & Step Up Transformers
Whether you’re stepping down from 480V to 220V or stepping up from 220V to 480V, getting the right transformer means understanding both voltage and phase.
If you’re running a US-standard building feed and your machine needs 220V 3 phase, you’ll need a 480V to 220V 3 phase transformer. If your controls only need single-phase power, then a 480V to 220V single phase transformer might be the better fit.
On the flip side, if you’re in a facility that only supplies 220V but you’ve got equipment rated for 480V, a 220V to 480V step up transformer is your go-to—especially if you’re integrating European or industrial legacy gear.
Here’s what we often supply:
- 480V to 220V step down transformerfor HVAC, compressors, and pumps
- 220V to 480V 3 phase transformerfor packaging lines and export-oriented panels
- Step up transformer 220V to 480Vwith sealed enclosures for outdoor install
- 480V to 220V transformerwith built-in breakers or taps for versatile use

They’re usually the same in function. The “step down” label emphasizes direction—from higher to lower voltage. A 480V to 220V transformer always reduces voltage unless otherwise designed.
Yes, we supply dry-type 480V to 220V 3 phase transformers in standard capacities from 25 to 500 kVA. These are ideal for imported machinery or building systems requiring 220V input.
Absolutely. It’s commonly used for HVAC controls, lighting loads, and isolated single-phase panels in 480V distribution systems.
You’ll need a step up transformer 220V to 480V, often with isolation built in. Available in both single phase and 3 phase configurations, depending on your source and load.
Functionally no—the step-up label just clarifies the voltage direction. But it’s always good to confirm your load type and power supply phase before choosing.
