The patented Accu-CT split-core current transformer technology delivers exceptional linearity and low-end accuracy. Developed specifically for solar inverter, variable speed motor drive, and other applications where there are large variations in current. The 100:1 turndown ratio of Accu-CTs is ten times better than industry standard CTs. The unique one-handed opening and closing mechanism makes installation a snap.
ACTL series CTs are available in both standard and revenue-grade accuracy models. Revenue grade models ship with a serialized certificate of calibration.
