Feature: Three-phase DT-3 transformer with a 225 kVA rating and copper windings delivering 480 V primary to 208Y/120 V secondary at 60 Hz. Business impact: The rugged, fully enclosed design reduces heat buildup and supports continuous loading, improving voltage stability and equipment reliability in demanding environments. Application: Ideal for control panels, motor starter assemblies, and process equipment in manufacturing facilities where uptime matters. Feature: Dual taps at +2.5% FCAN and -2.5% FCBN enable on-site voltage compensation. Business impact: Maintains output within tight tolerances despite supply variations, reducing nuisance tripping and protecting sensitive loads. Application: Control cabinets, PLC racks, and machine interfaces where voltage regulation is critical. Feature: Totally enclosed non-ventilated enclosure with NEMA 2 protection and WS35 weather shield. Business impact: Delivers dust, moisture, and environmental protection, enabling reliable operation in damp or dirty plant areas without frequent enclosure maintenance. Application: Indoor footprints and outdoor installations in challenging industrial environments. Feature: Copper windings and a 150 °C rise insulation class. Business impact: Higher conductivity and insulation margin improve efficiency, peak-load handling, and long-term durability, reducing thermal wear and extending transformer life. Application: Heavy-load feeders feeding motors, presses, and conveyors in continuous operation. Feature: UL Listed certification and DT-3 design for safety and procurement ease. Business impact: Simplifies qualification processes, reduces risk during audits, and accelerates project schedules for OEMs and integrators. Application: Panel builders, machine builders, and distribution partners seeking predictable lifecycle costs. Feature: Weathershield WS35 option and measured footprint for layout planning. Business impact: Eases retrofit work and new installs with predictable cabinet sizing and mounting, reducing field adjustments and procurement waste. Application: Retrofit upgrades and new builds in harsh or space-constrained facilities. Together these features translate into measurable outcomes: faster commissioning, fewer site adjustments, reduced energy losses, and a lower total cost of ownership over the transformer’s lifecycle.

FAQs
The V48D28E22CUNV supports a 480 V primary input and 208Y/120 V secondary output in a three-phase configuration. It uses a DT-3 enclosure with a NEMA 2 rating and WS35 weather shield when specified. Ensure cabinet layout provides 36.23 in depth, 44.2 in width, and 75 in height, and verify UL Listed compliance during procurement.
Key specs include a 225 kVA rating, 60 Hz operation, primary 480 V, secondary 208Y/120 V, and taps of 2 at +2.5% FCAN and 2 at -2.5% FCBN. This provides robust capacity for peak loads while tolerating supply variations, reducing voltage dips for motor drives and PLCs. Copper windings also reduce losses during heavy operation.
Ideal for industrial controls, panel boards, and machine rooms in manufacturing, process facilities, and packaging lines. The DT-3 totally enclosed design, UL Listed certification, and 60 Hz compatibility make it reliable in harsh environments where uptime and voltage stability are critical. The 225 kVA rating supports medium-scale feeders for equipment groups.
UL Listed confirms compliance with safety standards for electrical installations, while the NEMA 2 enclosure indicates dust and moisture protection for indoor use. The WS35 weather shield option adds outdoor or damp-area capability. These certifications simplify audits, reduce procurement risk, and support standardized parts across sites.
The enclosed DT-3 design minimizes cooling needs and maintenance frequency, lowering lifecycle costs. Copper windings and solid insulation improve reliability under continuous loads, reducing downtime. Voltage taps allow site variation compensation, further stabilizing performance and extending equipment life, which contributes to a favorable return on investment for OEMs and end users.
