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.
