This NK Technologies AT series current transducer combines a split-core current transformer and signal conditioner with top-mounted terminals, and is suitable for use in industrial automation systems. The transducer provides average root-mean-square (RMS) measurement for sinusoidal alternating current waveforms, with an accuracy of 1.0% full scale (FS) and a response time of 100 ms for voltage output models and 300 ms for current output models (10-90% step change). User-selectable input current ranges reduce inventory needed. This current transducer is Underwriters Laboratories (UL) listed and Conformité Européenne (CE) certified for quality assurance. It is suitable for monitoring linear, constant-speed alternating current (AC) loads that produce sinusoidal waveforms.SpecificationsFrequency Range50-60 Hz*Insulation Voltage1,270 VAC UL ListedOutput Loading1 M ohm minimumOperating Temperature-20 C to 50 C* 20-100 Hz for 4-20 mADC modelsCurrent transducers are used to detect electrical current flowing in a wire or cable, and to generate an electrical signal proportional to the current for measurement or control. The transducer consists of an electrical winding, a magnetic core, and a signal conditioner. When current flows through a wire, the transducer winding generates a current, which produces a magnetic field in the core, which then creates a proportional current or voltage output signal. Current transducers are used in industrial automation systems for monitoring, alarming, and equipment control.NK Technologies manufactures electrical sensors. The company, founded in 1982 and headquartered in San Jose, CA, meets International Organization for Standardization (ISO) standards 9001 and 14001.
