Overview

The SolaHD E2H30SCU is a ventilated distribution transformer designed for reliable 3-phase power conversion in industrial and commercial applications. Rated at 30 KVA, this transformer steps down 480V primary voltage to 208V secondary voltage at 60 Hz, making it ideal for facilities requiring compatible voltage levels for equipment operation. The Delta-Wye connection configuration ensures balanced load distribution and simplifies integration into existing three-phase systems. Constructed with copper windings, the E2H30SCU offers superior thermal conductivity and electrical efficiency compared to aluminium alternatives, reducing energy losses and improving overall system performance. The transformer features seven adjustable taps, allowing precise voltage regulation to accommodate varying load requirements and maintain stable output under fluctuating conditions. With a temperature rating of 150°C, it operates reliably in harsh environments without compromising performance. Compliance with DOE 10 Cfr P431 and DOE 2016 standards guarantees energy efficiency and environmental responsibility, while UL Listing E25872 certification ensures compliance with rigorous safety and fire resistance requirements. The NEMA Type 1 enclosure provides protection against dust and non-corrosive contaminants, making it suitable for indoor installation in standard industrial settings. Applications include power distribution in manufacturing plants, data centers, commercial buildings, and facilities requiring stable 208V power for sensitive equipment. The compact footprint and modular design facilitate straightforward installation and integration into new or existing systems. With copper windings for enhanced durability and efficiency, the E2H30SCU delivers long service life and low maintenance requirements, making it a cost-effective solution for critical power distribution needs.
