240V Single Phase to 480V 3 Phase
240V Single Phase to 480V 3 Phase – One Integrated System
This is more than a transformer—it’s a complete solution combining phase conversion and voltage step-up in one pre-engineered unit. Designed for repeatable deployment across modular sites, legacy buildings, and off-grid facilities.
Electrical contractors, system integrators, and modular equipment providers rely on Shinenergy’s UL-listed, batch-ready systems to simplify rollouts and ensure consistent specs—no matter the site. We support export packagers and regional distributors with fast lead times and matched documentation.
Solar Deployment Across Remote PV Microgrids – California, USA
A solar integrator managing off-grid microgrids in Fresno County needed to power 480V irrigation systems using single-phase 240V inverter output. We supplied pre-matched conversion systems installed between inverter banks and distribution panels. They deployed 20+ units across farming sites. According to the PM: “Instead of redesigning each site, we rolled out one spec across all.”
Energy Storage Telecom Backup Rollout – Alberta, Canada
Telecom Backup Rollout – Alberta, Canada
For a telecom network’s remote battery sites, only 240V single-phase grid was available. The integrator installed our system between PCS output and critical loads—HVAC, rectifiers, and battery control units requiring 480V three-phase. 60+ systems were batch-deployed in steel enclosures. The site contractor said: “Your units saved us days of configuration—we plug and power.”
Data Center Modular Edge Containers – Singapore & Malaysia
Modular Edge Containers – Singapore & Malaysia
A modular DC manufacturer embedded our step-up system inside 40ft edge containers, beside the breaker panel. With only 240V single-phase at many deployment sites, the system delivered clean 480V three-phase to power UPS and air-cooled in-row units. The repeatable footprint helped avoid site-specific redesign. “It scaled beautifully,” said their regional lead.
Wind + Hydrogen Containerized Electrolyzer Pilot – Inner Mongolia
Small wind turbines feeding 240V single-phase were connected to mobile hydrogen stations. Our system, installed in the rear panel of each electrolyzer container, converted that into 480V three-phase for pump drives and control power. The integrator deployed 12 units, citing minimal startup tuning and robust phase balancing under wind variance.
Medical Clinic Upgrade Program – Luzon, Philippines
15 regional clinics were upgrading to 480V diagnostic machines, but utility access remained 240V single-phase. Our systems were wall-mounted beside main disconnects, enabling seamless 480V three-phase delivery for MRI and sterilizer units—without changing upstream infrastructure. Facility managers appreciated the quiet operation and quick commissioning. “No rewiring, no delay—we kept the clinic open.”

Understanding 240V to 480V Phase-Voltage Conversions
In real-world power systems, things are rarely plug-and-play—especially when you need to jump from 240V single-phase to 480V three-phase, or step down in reverse. That’s where the terminology around step-up transformers, phase converters, and single-to-three-phase power systems often gets misused.
A 240 volt single phase to 480 volt 3 phase transformer isn’t a single device—it’s a combination of components, each with a clear role. You’ll need a rotary or digital phase converter to generate the third leg, and a transformer to elevate the voltage. At Shinenergy, we build pre-matched units that integrate both, tested and labeled for ease of installation. They’re used in farm equipment upgrades, rural telecom power hubs, and mobile containerized systems.
On the flip side, if you have 480V three-phase and need 240V single-phase for lights, sensors, or HMIs, a compact transformer can easily bridge the gap—so long as you size it correctly.
No matter your direction—step-up or step-down, single or three-phase—understanding the path is the first step. Let us handle the hardware.
Not as a standalone transformer. You’ll need a combined system: typically, a rotary phase converter for phase generation and a step-up transformer for voltage boost.
We’ve seen this applied in rural manufacturing sites, where 240V single-phase service is common, but the equipment demands 480V three-phase. Our clients use it to run CNCs, chillers, and small automation lines—especially in regions without three-phase utility.
Absolutely. This is a common setup for providing 240V single-phase output to PLCs, lighting, or panel-mounted equipment inside a larger 480V system.
Yes. For setups requiring both phase and voltage conversion, Shinenergy supplies fully matched systems—with labeled terminals, consistent specs, and rapid batch delivery for contractors and integrators.
Yes—for voltage reduction only. If your load is single-phase, this transformer steps down from a 480V three-phase supply. Just remember, it doesn’t isolate or regenerate a neutral—check your wiring layout.
