ATO Series Split-Core Current Transformers

LEM ATO series split-core current transformers are specifically designed for the electronic measurement of AC waveform current, guaranteeing galvanic isolation between the main and secondary circuits. These current transformers range from 0 A to 125 A and are mainly intended to be mounted on the main circuit. ATO transformers are adaptable and provide both voltage and current outputs. Their self-powered capabilities, small size, and apertures ranging in diameter from 10 mm to 16 mm make them ideal for many uses. The ATO current transformers use air-core technology to meet strict requirements like IEC 61869 for phase displacement and ratio error, making them especially well-suited for new smart grid applications.
