🏗️ Common Applications
Need help sizing a transformer? Our engineers will match the right KVA to your load.
This 112.5 KVA dry-type transformer converts 480V three-phase Delta power to 208Y/120V, providing both three-phase 208V and single-phase 120V outputs from a single unit. It's the standard voltage conversion for commercial buildings, industrial facilities, and machine shops that receive 480V service but need 208/120V for equipment, lighting, and receptacles.
Dry-type transformers require no oil filling or maintenance — just install, wire, and forget. The NEMA 3R enclosure allows indoor or outdoor installation. Whether you're building out a new shop or adding capacity to an existing facility, this transformer delivers reliable voltage conversion for the long haul.
