Overview

The SolaHD ES5HF50S is a low-temperature-rise ventilated distribution transformer designed for reliable industrial and commercial power distribution. Rated at 50kVA, this transformer converts 240/480V primary input to 120/240V secondary output at 60Hz, making it ideal for stepping down voltage in facilities with 240/480V feed lines. The 115°C temperature rise rating ensures efficient thermal management, reducing heat stress and extending operational life even under continuous heavy loads. With primary currents of 208/104A and secondary currents of 416/208A, the ES5HF50S handles substantial power demands while maintaining stability. UL Listed to E25872 and UL 1561 standards, this transformer meets rigorous safety and performance requirements for critical applications. Its ventilated design promotes natural airflow, eliminating the need for forced cooling in most environments. Common applications include powering motor control centers, lighting systems, control panels, and other industrial equipment where stable, low-voltage distribution is required. The compact footprint and durable construction simplify installation in both new and retrofit projects. Compared to standard transformers with higher temperature rises, the ES5HF50S reduces energy losses and maintenance costs over its lifespan. Trust SolaHD’s US-manufactured quality for dependable power conversion in demanding environments.
