Overview

The SolaHD E5H300S is a 300 KVA ventilated distribution transformer designed for reliable power distribution in industrial and commercial settings. This unit features a primary voltage of 480 V and a secondary voltage of 240 V, operating at 60 Hz across three phases. Its robust construction includes aluminium windings, ensuring efficient heat dissipation and longevity. The NEMA Type 1 enclosure provides protection against dust and light moisture, making it suitable for indoor installations. Compliance with DOE 10 CFR P431 and DOE 2016 standards, along with UL E25872 listing, guarantees adherence to strict safety and performance benchmarks. The Delta-Delta W/ Ct connection type offers installation flexibility, and the seven-tap capability allows for precise voltage regulation to accommodate varying load conditions. With a temperature rating of 150 degrees C, the E5H300S is engineered to operate effectively in environments with elevated temperatures. The E5H300S is optimized for high-efficiency operation, meeting Department of Energy (DOE) 2016 efficiency standards for liquid-immersed and dry-type transformers, ensuring reduced energy losses and lower operational costs. The seven-tap design provides voltage adjustment flexibility, with taps typically ranging from -2.5% to +2.5% in 0.625% increments, allowing for precise tuning to match specific application requirements. The Delta-Delta connection configuration ensures compatibility with balanced three-phase systems while providing neutral stability for secondary loads. The aluminium windings contribute to lightweight construction and corrosion resistance, further enhancing durability in demanding environments. UL listing E25872 confirms compliance with North American safety standards, including electrical insulation and fire resistance criteria. This transformer is ideal for applications such as manufacturing facilities, data centers, commercial buildings, and HVAC systems where consistent, high-quality three-phase power is critical for equipment performance and operational reliability.
