PowerTower Series
Compact low-voltage step-down transformers — clean, reliable 208Y/120V power from a 480V source, in a fraction of the footprint.
Overview
PowerTower Series | Compact Low Voltage Transformers
The PowerTower Series from delivers clean, reliable 480V to 208Y/120V step-down power in a revolutionary vertical enclosure. Toroidal cores inside rugged NEMA 2 cabinets cut size and weight by 40–50% while running whisper-quiet and cool (temperature rise at full load is less than 80°C / 176°F).
Dry-type single-phase and three-phase low voltage (<600 VAC) distribution transformers, UL listed, made in the USA, and built for continuous-duty indoor use.
Key Benefits
- 40–50% reduction in volume – fits anywhere
- Weighs 40% less, generating considerable savings in transport and installation costs
- Pays for itself quickly in energy savings – efficiency well exceeds the guidelines of NEMA’s new Premium Efficiency Transformer Program
- Temperature rise at full load is less than 80°C (176°F) Ultra-quiet toroidal operation – ideal near occupied spaces
Applications & Industries
- Data Centers & Colocation Facilities Low EMI, minimal heat generation, and tiny footprint allow installation right next to racks or in cramped electrical rooms. Reduces cooling costs and protects sensitive networking gear.
- Healthcare Facilities Whisper-quiet operation near patient areas and reliable isolated power.
- Educational Institutions Noise-free performance for schools, universities, libraries, and churches.
- Commercial & Retail Office buildings, shopping malls, and stores benefit from the dramatically smaller footprint.
- Industrial & Manufacturing Reliable step-down power with major space savings on the factory floor.
Specifications
Technical Specifications Available in both Single Phase and Three Phase. All models feature 480V primary to 208Y/120V secondary (standard). Custom voltages available upon request.
