The DT Series Large Aperture Current Transducers combines a hall effect sensor and signal conditioner into a single package for use in dc-current applications up to 1,200 amps. Factory calibrated ranges simplify operation and eliminate zero and span pots. Industry standard 4 to 20 mA, 0 to 5 Vdc or 0 to 10 Vdc outputs are magnetically isolated from the input to provide maximum safety, and eliminate insertion losses. Internal power regulation delivers reliable operation and helps keep installation costs low, even in applications with unregulated power. A DIN-rail mount enclosure makes installation easy.
“DT series current transducers provide design and process engineers with a rich source of equipment information,” says Philip Gregory, President, NK Technologies. “The devices are said to be economical and reliable tools for monitoring equipment status, detecting process variations and allow taking corrective action before a failure occurs, and ensuring personnel safety.”
The ability to monitor circuit up to 1,200A makes the large aperture current transducers well suited for applications that include:
- Monitoring load and charging currents, and verifying operation, of battery banks
- Measuring traction power or auxiliary loads in transportation applications
- Monitoring dc powered motors in cranes, saws, sorters, and positioning equipment
- Measuring produced or consumed current, and detecting mechanical problems before a failure, in wind and solar applications.
Test and evaluation units are available to OEMs at no cost. The Engineering Resources section of NK Technologies website provides numerous application notes, and technology white paper on current sensing technology.
