Transducers for high currents
7 September 2005
Test & Measurement
LEM has added two members to its IT family of current transducers to address high-current applications. The IT 400-S and the IT 700-S are specified respectively for 400 and 700 A r.m.s. nominal. As with other members of the family, they offer very high accuracy, based on resolution better than 0,05 ppm, linearity better than 3 ppm and an initial offset between 30 and 50 ppm. Thermal offset drift is extremely low, at 0,5 ppm/K.
Featuring galvanic isolation, the IT 400-S and IT 700-S can be used for current measurement of any kind of waveform (including DC, AC, mixed and complex). They have been designed to operate from a bipolar ±15 V d.c. power supply and will accommodate round primary conductors of 26 and 30 mm diameter respectively.
In addition to their normal current output, the transducers offer an additional output indicating the transducer state (opened or closed contacts), and an external LED showing the normal operation.
With an operating temperature range of +10 to +50°C, the transducers will find applications in high-precision power supplies and high-performance gradient amplifiers for magnetic resonance imaging and other medical equipment, and also calibration test benches in laboratories and test departments. They can also be used as interfaces for power analysers when high accuracy is required.
