Portable Transformers


Our Portable Transformers, also known as Portable Step-Down Units, are industrial portable power units that are common place on all project and job sites where an existing higher voltage (600VAC, 480VAC) needs to be reduced / stepped down (240 / 208 / 120VAC) to provide electrical power to various construction and maintenance equipment. Models are available in any voltage requirement in WYE (“Y”) or Delta configurations ranging in size up to 2500kVA. Common units: 25KVA, 45KVA, 75KVA and 150KVA.
