DC Power Rectifiers
Ohio Magnetics’ DC Power Supplies for lifting magnets are available in both a fixed voltage output (usually 230 VDC or 115 VDC) and a variable voltage output (usually 0-230 VDC or 0-300 VDC). Fixed voltage output type DC Power Supplies are used in most general magnet applications. Variable voltage supplies are used in applications of fanning, boost/carry, flux reduction, constant flux regulation, etc.
