With dry-type construction, 220°C insulation, and Delta-Wye options, it ensures stable, low-loss performance in commercial and industrial settings.

Shinenergy offers UL/CSA-certified builds, custom enclosures, and fast-turnaround batch production for EPCs, OEMs, and facility upgrades.

Solar – Boosting Low-Voltage AC Output to Match Grid Standards

In commercial PV projects, especially where microinverters or string inverters output at 208V, this transformer is installed between the inverter cluster and the main grid-tie switchgear, stepping up to 480V to meet interconnection voltage requirements.
✅ It ensures that solar-generated power is compatible with local grid standards.
📍 Used in a rooftop PV deployment for a California retail chain, 10+ sites.

Energy Storage – Matching Inverter Output to Site Distribution

Energy storage systems often output 208V, but backup or grid-feed infrastructure expects 480V. Our 200 kVA step-up transformer is installed between battery inverter racks and the building’s switchboard, converting voltage for seamless power handoff.
✅ It stabilizes voltage levels and reduces mismatch during peak discharge.
📍 Deployed in a Massachusetts EV charging station with integrated battery storage.

Data Center – Supporting New UPS Banks or High-Voltage Racks

Many edge data centers and secondary server rooms rely on 208V feeds. However, as power density grows, equipment like UPS units or PDUs require 480V input. This transformer is installed next to power distribution frames, bridging the voltage gap.
✅ It allows infrastructure expansion without costly utility upgrades.
📍 Installed at a hyperscale operator’s containerized node project in Ohio.

Wind + Hydrogen – Ensuring System Compatibility at Remote Sites

Small-scale electrolysis systems powered by wind-turbines often receive 208V service but require 480V for compressors or controllers. This transformer is mounted between the local turbine output and electrolyzer unit, adjusting voltage precisely.
✅ It enables hydrogen systems to run on standard wind outputs without overdesign.
📍 Integrated into a mobile hydrogen test station in Inner Mongolia’s desert zone.

Medical – Enabling Specialized Equipment in Legacy Buildings

In older hospitals or labs with only 208V infrastructure, new sterilization or imaging machines need 480V. This transformer is installed in electrical closets or equipment bays, allowing new systems to operate without total rewiring.
✅ It solves voltage mismatch without disrupting existing power zones.
📍 Chosen by a Southeast Asia medical supplier to retrofit 60+ clinics.

Why You Might Need a 208V to 480V Step Up Transformer

If your facility runs on 208V but your equipment is rated for 480V, you need a step up solution that works—reliably, efficiently, and with minimal disruption. That’s where a 208V to 480V step up transformer comes in.

We regularly supply both 3 phase 208V to 480V step up transformers and single phase models to customers upgrading old buildings, integrating new equipment, or expanding production. These transformers are essential for running newer machines—like 480V-rated HVAC systems, presses, or automation units—on legacy infrastructure.

For smaller systems, we provide units like 20 kVA 208V to 480V step up transformer or even 3.5 kVA for localized circuits. And if you’re working on federal or commercial contracts, we offer solutions that meet specific standards, including UL, NEMA, and CSA.

Installation is straightforward—we ship each transformer with a detailed wiring diagram, and we’re happy to assist with selection, whether you’re trying to wire a step up transformer yourself or specifying for an EPC project.

With Shinenergy, you get more than a box—you get the right voltage, in the right spec, for the real world.

What is a 208V to 480V step up transformer used for?

It’s designed to convert standard 208V input—common in older commercial buildings—into 480V three-phase power for equipment such as CNC machines, chillers, or VFDs. Widely used in retrofits and industrial upgrades.

Is there a difference between a 208V to 480V 3 phase step up transformer and a single phase one?

Yes. A 3 phase step up transformer 208V to 480V is for powering three-phase loads like motors or heavy machinery. A single phase step up transformer 208V to 480V is used for smaller, specific loads requiring 480V but sourced from single-phase 208V.

Do you provide a 208V to 480V step up transformer wiring diagram?

Absolutely. Every order includes a detailed wiring diagram—single line and terminal maps—especially helpful when installing in Delta-Wye or Delta-Delta configurations.

Is there a 208V to 480V step up transformer calculator I can use?

Yes. Our team can help you size your transformer based on your load’s kW/kVA, startup current, and duty cycle. Or use our online step up transformer calculator to input your voltage and current to determine capacity.

Do you offer 20 kVA or 3.5 kVA 208V to 480V step up transformers?

Yes. We supply 208V to 480V step up transformers in sizes from 3 kVA up to 500 kVA, including 20 kVA single phase and three-phase options for OEM and retrofit needs.

Can you support federal or government specs for 208V to 480V step up transformers?

Yes. We support federal 208V to 480V step up transformer tenders with UL/CSA listings, NEMA 3R/4 enclosures, and MIL-SPEC coating options if required.

How should I wire a step up 208V to 480V transformer safely?

Always refer to the transformer wiring diagram, ensure proper phase alignment, grounding, and protection devices. For 3 phase 208V to 480V, confirm line-to-line voltage and neutral arrangement.
