Overview

The SolaHD E81H15S is a 15 KVA ventilated distribution transformer engineered for reliable 3-phase power distribution in industrial environments. Operating at 480V AC on both primary and secondary sides with a 60 Hz frequency, this transformer delivers consistent voltage regulation for demanding applications. Its delta-wye connection configuration ensures optimal load balancing and phase stability, critical for sensitive equipment and high-capacity loads. Constructed with high-grade aluminium windings, the E81H15S offers superior thermal conductivity and durability, rated for operation up to 150°C. The transformer features 7 adjustable taps, enabling precise voltage adjustment (±2.5% per tap) to accommodate varying load demands and maintain system stability. This flexibility is essential for facilities with fluctuating power requirements or those requiring compliance with specific voltage tolerances. Housed in a NEMA Type 1 enclosure, the E81H15S provides protection against dust, dirt, and light splashes, making it suitable for indoor industrial applications. The enclosure design promotes natural ventilation, reducing the need for forced cooling and minimizing maintenance overhead. Certified to UL E25872 and compliant with DOE 10 Cfr P431 and DOE 2016 energy efficiency standards, this transformer meets stringent safety and performance criteria. Ideal for motor control centers, industrial substations, manufacturing plants, and data centers, the E81H15S ensures reliable power delivery with minimal downtime. Its compact footprint and robust construction make it a cost-effective solution for new installations or system upgrades. With a 3-phase configuration and delta-wye wiring, it integrates seamlessly into existing power distribution networks while providing the reliability required for critical operations.
