225 kva step up transformer 240 to 480 3 phase
If your site runs on 240V but new equipment requires 480V, this 225 kVA step up transformer gives you the power to adapt. Whether you’re installing machinery, expanding a solar inverter array, or upgrading building systems, it bridges the voltage gap without compromising reliability.
It’s three-phase, dry-type, and built for demanding environments. Compact enough for mechanical rooms, durable enough for industrial floors. We’ve supplied this model for factories, hospitals, energy projects, and commercial sites that needed stable 480V from a 240V supply.
Backed by Shinenergy’s in-house engineering and ISO-certified manufacturing, this transformer supports UL/CE standards and custom builds. Whether you’re specifying a new system or replacing a legacy unit, we’ll make sure it fits—electrically and operationally.
Solar Power Systems
In commercial solar-plus-storage projects, this transformer is typically installed at the output of the battery inverter, where the system generates 240V three-phase power but the grid or equipment requires 480V.
It ensures safe, reliable voltage boosting for utility tie-in or high-voltage AC loads like heat pumps and industrial HVAC.
📍 Used in a Texas-based 800kW hybrid solar farm retrofit to adapt inverter output to commercial building power systems.
Energy Storage Systems
Many BESS (Battery Energy Storage Systems) designed for modular deployment run on 240V AC internally. To connect these systems to facility loads or local grids operating at 480V, the transformer is placed at the system boundary or main switchboard, serving as the final voltage lift.
✅ It prevents inverter oversizing while maintaining system efficiency and safety.
📍 Shinenergy supplied 6 units to an energy integrator in Arizona for containerized lithium-ion storage stations.
Data Centers
In small to medium-sized data centers, branch circuits or edge modules may only provide 240V power. This transformer is installed in the main distribution room, stepping voltage up to 480V for UPS bypass paths, HVAC units, or legacy high-voltage IT systems.
✅ It helps maintain voltage uniformity across distributed subsystems, especially during upgrades.
📍 Adopted by a Philippine telecom facility during a three-phase system standardization project.
Wind-to-Hydrogen Projects
Some electrolyzer skids are designed to accept 480V input, but the local renewable source (wind or microgrid) may only offer 240V AC. In these scenarios, the transformer is placed between the wind inverter and the electrolyzer control cabinet, elevating supply voltage to required levels.
✅ It ensures the system can function continuously under variable load and low-wind conditions.
📍 Integrated into a decentralized wind-hydrogen test platform in Inner Mongolia.
Medical Facilities
When hospitals or clinics expand their facilities, they often reuse older power systems based on 240V. To power new 480V-dependent MRI chillers, autoclave systems, or HVAC compressors, this transformer is installed near the central mechanical room, connecting legacy panels to high-voltage devices.
✅ It enables staged upgrades without full rewiring or service interruption.
📍 Provided to a medical contractor in Colombia modernizing a regional trauma center with mixed-voltage infrastructure.

Why 3 Phase Variable Transformers Are Essential for Testing and Control
In industrial and testing environments, not every system works well with fixed voltage. That’s where a 3 phase variable transformer comes in—allowing real-time voltage control across all three lines. Whether you’re testing motors, inverters, or simulating grid conditions, having full command over your power source is key.
Also referred to as a 3 phase variable voltage transformer, this equipment lets engineers fine-tune output levels from 0V to full rated voltage. It’s widely used in power labs, manufacturing test benches, and research centers dealing with equipment qualification, aging tests, or voltage fluctuation tolerance.
At Shinenergy, we manufacture dry-type 3-phase variable transformers ranging from 30 kVA to 500 kVA, available in both manual and servo-controlled versions. Our clients rely on them for reliable, stable output and repeatable results—especially in high-sensitivity applications like PCS and UPS validation.
A 3 phase variable transformer is used to adjust output voltage across all three phases. It’s commonly deployed in test benches, industrial control setups, and lab environments where precise voltage control is critical.
Not really. Both terms refer to the same equipment. “Variable voltage” emphasizes the output adjustment capability, but both describe transformers that provide controlled, adjustable 3-phase AC power.
Yes. These transformers are ideal for simulating brownouts, overvoltage, and imbalance conditions. They’re widely used in inverter testing, motor soft-start testing, and PCS validation.
Both. You can select manual (knob/handwheel) control for lab setups or automated servo-control for repeatable test sequences. Shinenergy supports both configurations, including PLC interface options.
