Description
EE84H75S Emerson Sola-HD Isolation Transformer 208V 75000VA Wire Leads Wire Leads 480V, 277V Floor Mount
The SolaHD EE84H75S is a 75 KVA ventilated distribution transformer engineered for industrial and commercial power distribution systems. This DOE 2016 and UL E25872 compliant transformer delivers reliable 3-phase power at 60 Hz with a primary voltage of 208V and a secondary voltage of 480V. Its Delta-Wye connection configuration ensures compatibility with standard 3-phase power networks, while the 7-tap voltage regulation system allows precise adjustment to accommodate varying load demands and maintain optimal performance. Constructed with aluminium windings, the EE84H75S offers superior thermal conductivity and durability, reducing energy losses and extending service life. The transformer operates efficiently at a temperature rating of 150°C, making it suitable for high-temperature environments common in manufacturing plants, data centers, and utility substations. The NEMA Type 1 enclosure provides protection against dust, dirt, and non-hazardous contaminants, ensuring reliable operation in indoor industrial settings. Key specifications include a 75 KVA rating, 3-phase operation, and compliance with DOE 10 Cfr P431 (DOE 2016) and UL E25872 standards. Its compact design and aluminium construction make it lightweight and easy to install, while the 7-tap system allows for flexible voltage adjustment within ±10% of nominal. Whether used in heavy machinery applications, process control systems, or power distribution networks, the EE84H75S delivers consistent performance, energy efficiency, and long-term reliability. Ideal for facilities requiring robust power conversion with minimal maintenance, this transformer is a cost-effective solution for modern power distribution challenges.
