Ohio Magnetics - DC Power Rectifiers for Lifting Magnets

SHARE
Ohio Magnetics specializes in providing versatile DC power rectifiers designed to efficiently power lifting magnets. Their solutions cater to a range of applications with both fixed and variable voltage outputs. Fixed voltage outputs, most commonly at 230 VDC or 115 VDC, are suited for general magnet applications, ensuring reliable and consistent performance. Meanwhile, variable voltage outputs, typically ranging from 0-230 VDC to 0-300 VDC, offer advanced functionality for specialized applications such as fanning, boost/carry operations, flux reduction, and constant flux regulation. Ohio Magnetics' DC power supplies are engineered to meet rigorous technical standards, accommodating various optional features to enhance operational flexibility and performance. Made in the USA, these rectifiers are built to support industrial environments and are backed by Ohio Magnetics' commitment to quality.
