AlfaMag Standard EI Laminate AMPT Series Power Transformers
AlfaMag’s AMPT Series power isolation transformers are ideally suited for applications requiring high isolation between the power input and the load. Constructed with a UL recognized Class B, 130 deg C insulation system, the AMPT Series transformers are designed to accommodate input voltages of 115VAC or 230VAC, 50/60Hz, with output voltages from 5VAC to 230VAC (series or parallel connection). Constructed with a dual segment bobbin, the primary to secondary isolation is 3500Vrms minimum.
