3 phase step down transformer 480 to 208
Standardized power. Site after site.
This 167 kVA 3-phase transformer steps 240V down to 208V with precision—ideal for buildings, plants, or data rooms where equipment requires a stable 208V supply. It’s especially useful when your existing utility feed is 240V Delta, but your load demands a 208V Wye system.
Shinenergy delivers every unit fully tested, dry-type, UL-listed, and spec-locked—so system integrators and contractors can deploy across multiple sites without changing layout, cable routing, or load specs. Whether you’re feeding HVAC, UPS, or lighting panels, this unit fits right in.
Used by commercial electricians, modular equipment builders, and energy retrofit teams, it’s the go-to model when repeatable deployment and safe isolation are non-negotiable.
Office Loads in Utility-Scale PV Farms | Location: Bakersfield, California
A solar EPC managing multiple sites in Central California used Shinenergy 167 kVA transformers to power 208V-rated lighting, HVAC, and workstations in control rooms. The on-site utility provided 240V 3-phase Delta; step-down transformers were installed near load panels inside each O&M building.
“We didn’t change any wiring between sites. One transformer spec, multiple installs—perfect.”
Auxiliary Panel Conversion | Location: Alberta, Canada
In a BESS deployment outside Edmonton, the PCS system delivered 240V output, but the site’s monitoring systems and fire control panels required 208V Wye. Shinenergy’s 167 kVA transformers were cabinet-mounted at each container cluster, decoupling auxiliary loads from inverter output.
“We matched layout across 12 enclosures. No surprises during inspection.”
Step-Down at PDU Distribution Layer | Location: Dallas, Texas
A colocation provider in Texas standardized 167 kVA units at the output of their UPS systems. Incoming service was 240V Delta, while client racks demanded 208V Wye. The transformers were floor-mounted behind each PDU corridor.
“These hit the sweet spot—compact, quiet, and consistent with NEC.”
Electrical Room Load Management | Location: Schleswig-Holstein, Germany
A wind-to-hydrogen research facility used 240V from microturbine arrays but needed 208V power for analytics equipment, building automation, and safety systems. Shinenergy’s dry-type units fed clean, isolated voltage to dedicated load branches.
“The test team didn’t even need to check twice—it was plug and run.”
Clean Voltage Supply for Facility Upgrades | Location: Birmingham, UK
A private hospital retrofitting its outpatient diagnostics center had legacy 240V feeds but required 208V for new diagnostic workstations and air-handling units. Transformers were wall-mounted in electrical closets, linked to isolated breakers.
“We used the same transformer across three floors. Labeling and wiring were dead simple.”

Choosing the Right 3 Phase Step Down Transformer for Your Project
Stepping voltage down seems simple—but the wrong transformer will cost you downtime, noise, and even failed inspections.
Whether you need to step down 240V to 208V, 380V to 220V, or 480V to 240V, the key is understanding your system’s grounding, phase type, and load profile. For example, a 3 phase 240 to 208V step down transformer is perfect for US retail locations where lighting and HVAC demand 208V Wye, but utility delivers 240V Delta.
Need to isolate 480V panels? We offer dry-type 480V 3 phase step down transformers, with or without neutral tap, based on your grounding plan. From hospitals in the UK to packaging lines in Texas, these units are installed behind panels, inside outdoor enclosures, or integrated directly into control cabinets.
Batch consistency matters. Whether you’re installing ten step down transformers 240 to 208 3 phase, or equipping containerized equipment with 380V to 220V step down transformers, we deliver labeled, tested, spec-matched units—ready for parallel deployment.
It reduces a higher input voltage (e.g. 480V, 380V, or 240V) to a lower output voltage (e.g. 208V, 220V, or 120V). These transformers are essential for matching utility supply to equipment voltage requirements in commercial and industrial settings.
Both reduce voltage, but they serve different input/output ranges. A step down transformer 240 to 208 3 phase is commonly used in US commercial buildings. A 480 to 240 3 phase step down transformer is more typical in large-scale industrial settings.
Wiring depends on whether you’re using Delta or Wye configurations. For example, in a 3 phase step down transformer 480 to 208, primary lines go to H1–H3, and the secondary lines come from X1–X3. Always follow the wiring diagram supplied with the unit, and ensure the system is grounded correctly.
Yes, but only if the transformer supports it. A step down transformer 3 phase to single phase can be used when loads are single phase, but sizing and tap placement are critical. We also offer dedicated models for 3-to-1 conversion.
Absolutely. All Shinenergy units ship with wiring diagrams and terminal schematics—Delta or Wye—based on the exact voltage combination (e.g. 480V to 240V, 380V to 220V). Diagrams are also available in PDF format.
Use your total load in amps and multiply by √3 × voltage, then divide by 1000 to get kVA. Add a 20% buffer. For example, if you’re stepping down from 460 to 230V 3 phase for a 180A load, you’d need a ~150–167 kVA transformer.
Smaller models like 5kVA step down transformers are typically used for lighting panels, control systems, or single machine loads. They are ideal for distributed panel-level step-downs where full-site conversion isn’t needed.
