Totally enclosed non-ventilated (TENV) DS-3 design reduces ventilation and cooling requirements, simplifying installation and reducing ongoing HVAC costs while delivering dependable power for confined spaces. Business impact: lower total cost of ownership and easier cabinet integration in control rooms and machine housings. Application: machine control panels and regional distribution enclosures in manufacturing facilities. The 15 kVA single-phase rating provides ample headroom for common load centers, improving system reliability and reducing the need for oversizing equipment. Application: panel boards and small machinery installations where space is at a premium. Primary voltage options of 208/416 V and secondary 120/240 V offer flexible integration with standard plant distributions and equipment, streamlining panel design and stocking. Application: systems that require quick, code-compliant connections with minimal wiring complexity. The programmable taps (+5% FCAN, -5% FCBN x2, +2.5% FCAN, -2.5% FCBN x4) enable voltage stabilization under fluctuating loads, improving equipment performance and protecting sensitive electronics. Application: voltage-sensitive drives and controls in dynamic production lines. Aluminum windings provide corrosion resistance and efficiency benefits while keeping weight manageable for field serviceability; frame 817N and a 19.5 in depth support sturdy installations in compact footprints. Application: rugged plant environments where maintenance access and durability matter. Warranty coverage (25-000) at one year from installation or 18 months from shipment adds predictable support and cost control. Application: long-term asset planning and service budgeting.

FAQs
Installation should follow the DS-3 design guidelines with the transformer mounted on a level, vibration-free base. Ensure adequate clearance for airflow around the enclosure, connect primary and secondary leads per the 208/416 V to 120/240 V configuration, and use proper lifting gear due to the 307 lb weight. Verify torque specs and secure grounding to prevent electrical noise and fault conditions.
The unit is a 15 kVA, single-phase dry-type transformer with primary voltages of 208 V and 416 V and secondary voltages of 120/240 V. It operates at 60 Hz and has a 150 °C rise. Winding material is aluminum, and the design is DS-3 with a 19.5 in depth, 37.53 in height, and 22.59 in width.
Best suited for machine control panels, compact power distribution in manufacturing facilities, and control rooms where space is limited. Its DS-3 design and dry-type construction enable easy installation in indoor plant environments, while the 15 kVA rating covers typical control circuits, drives, and small distribution loads with reliable performance.
Certifications vary by region; always verify current approvals with Eaton. The product notes indicate to contact the manufacturer for certifications. When planning installation, check for CE, UL, or regional approvals as required by your facility’s electrical code and safety standards.
The transformer is covered under Eaton’s policy with a one-year warranty from installation or eighteen months from shipment, whichever comes first. For maintenance, rely on aluminum windings and the DS-3 enclosure to reduce ventilation maintenance. Plan for routine inspections, verify taps during long-term operation, and maintain proper enclosure seals to prevent dust ingress.
