December 23, 2013. Onset has announced a series of high-performance, split-core current transformers for measuring AC current and amperage in commercial building energy audits, building commissioning studies, and other applications.
The Accu-CT Series current sensors—manufactured by Continental Control Systems and sold through Onset—are available in 20-, 50-, 100-, and 250-A models, all offering one-handed operation.
Key advantages include revenue-grade accuracy; 0.75-in. window opening; easy open and installation with one hand, even while wearing safety gloves; sufficient angle phase angle accuracy for energy measurements; and IEEE C57.13 and IEC 600440-1 accuracy over full temperature range and down to 1% of rated current
The current transformers are compatible with Onset HOBO stand-alone data loggers, web-based monitoring systems, and wireless data nodes. They are priced at $45 and are available directly from Onset.
