Description
NK Technologies AT2-420-24L-FD – AC Current Transducer (0-200 Amp Range)

- 4–20 mA Analog Signal Proportional to AC Current
- 2-Wire Loop Powered
- DIN Rail or Panel Mount
- Factory Calibrated with Five Year Warranty
AT/ATR-FD Series AC Current Transducers provide a current sensor and analog output signal conditioning in a single package. The large, easy-to-install solid-core design allows for quick installation even in applications where there are multiple conductors per phase. Just thread the conductor through the extra large aperture and reconnect on the other side. The transducer output is powered from excitation voltage of around 24 VDC, using just two wires. The sensor mounts on a back panel or a DIN rail, and is designed to accommodate wire sizes for loads up to 400 A.
AC Current Transducer Applications
- Monitor Large Machines
- Detect over or under-current conditions before they cause breakdowns or interlock one process with another.
- Water Delivery and Treatment
- Detect open discharge lines.
- Sense clogged filters or blocked intake to pumps.
- Measure increased current to show failing bearings or pump impeller cavitation.
- Generators
- Shed noncritical loads when demand reaches a set level.
