Industrial power conversion systems demand precise, reliable current measurement to maximize efficiency and protect critical equipment. Littelfuse industrial current sensors serve a broad range of applications: static converters for dc motor drives, solar inverters, ac variable speed drives, servo motor drives, uninterruptible power supplies, and switched-mode power supplies. To meet the diverse performance and packaging requirements of these applications, Littelfuse offers industrial current sensors across three core technologies.
