Current transducer range rises to 50A
RMS
Two new devices extend the current measuring range of the LEM HX series of PCB-mounting current transducers to 50A RMS.
Two new devices extend the current measuring range of the LEM HX series of PCB-mounting current transducers to 50A RMS The two new models, for 25 and 50A RMS nominal measurements, bring the total number of transducers in the range to 14, providing primary nominal current measurement of 3, 5, 10, 15, 20, 25 and 50A RMS with either a bipolar +/-12 to 15V or unipolar 12 to 15V power supply

Current sensors slip on in a trice
LEM has three families of split-core current sensors that can be clamped around a busbar or cable without moving the conductor.
Speedy installation for current transducers
LEM has new families of current transducers with an innovative design that dramatically reduces installation time.
Three more transducers with dual primary windings for 5, 10 and 15A RMS nominal ratings and sharing the same standard case size are also available.
The HX series uses open-loop Hall-effect technology to provide high performance and quality at a lower cost than existing equivalent models or previous generations.
This technology allows the transducers to measure DC, AC and pulse currents and provides galvanic isolation between the primary and output circuits.
The transducers require a mounting area of only 2.85cm2 and weigh only 8g.
They can measure up to three times the primary nominal current.
The clearance and creepage distances of more than 5.5mm makes these transducers particularly suitable for isolated current measurements in the lower and middle power ranges and provide a test isolation voltage of 3kV RMS/50Hz/1min.
The HX series transducers conform to the EN50178 standard, use UL94V0 recognised materials and are CE marked according to the European Directive 89/336/EEC.
They are particularly suitable for industrial applications and home appliances, such as variable speed drives, UPS, SMPS and air-conditioners.
They are covered by a five-year warranty.
