LEM compact transducer for high AC and DC currents
LEM has introduced a family of current transducers, DHR series, that offer dramatic savings in size of up to 75% compared to other current transducers.
Linearity is better than 0.001% and overall accuracy at ambient temperature is 0.05%.
Thermal offset drift is very low, at only 1mA/K.
Featuring galvanic isolation, the ITB 300-S can be used for current measurement of any type of waveforms (including DC, AC, mixed and complex).
It has been designed to operate from a bipolar +/-15 V DC power supply, and will accommodate a round primary conductor of up to 21.5 mm diameter.
In addition to its normal current output (150 mA for 300 A primary), an additional output indicating the transducer state (opened or closed contacts) is available.
The new model offers an extended operating temperature range of -40 to +85C, compared to the +10 to +50C of the IT models, allowing its use in a wider range of applications, including high precision power supplies, medical equipment, calibration units, precise and high stability inverters, power analysers and metering.
The transducer is CE marked, conforms to the EN 50178 and EN 50155 standards and is suitable for industrial and traction applications.
LEM Components offers these transducers with a two-year warranty.
