IT current transducers are high accuracy, large bandwidth trans-ducers which do not use Hall generators. The magnetic flux createdby the primary current IP is compensated by a secondary current.The zero-flux detector is a symmetry detector using two woundcores connected to a square-wave generator. The secondarycompensating current is an exact representation of the primarycurrent.

PRiME operates on the basic Rogowski principle. Instead of atraditional wound coil, the measuring head is made of a numberof sensor printed circuit boards (pcbs, each made of two sepa-rate air cored coils) mounted on a base-pcb. Each sensor PCBis connected in series so as to form two concentric loops. Theinduced voltage at their outputs is then integrated in order toobtain both amplitude and phase information for the currentbeing measured.

Current Transducers

The use of auto insertion equipment in the manufacturingof electronic assemblies is commonplace today. LEMproduces several types of PCB mounted transducersthat are designed with automated assembly in mind.These devices allow our customers to take advantage ofhigh volume production strategies giving them theadvantage necessary to remain competitive.

Designed for automated assemblyDesigned for automated assemblyDesigned for automated assemblyDesigned for automated assemblyDesigned for automated assembly

In addition to the benefit of automated assembly that anintegrated primary bus bar offers, it also has an importantimpact on the performance of the product. By locatingthe primary conductor in exactly the right place in relationto the secondary winding, we maximize the primary tosecondary coupling of the transducer. This givestransducers their excellent high frequency properties.

The current transducer, weighing only 10 g, requires only a small area onthe printed circuit board, and is optimally suited for automated productionlines.

Smallest PackagesSmallest PackagesSmallest PackagesSmallest PackagesSmallest Packages

Most current transducers are still designed for bipolarsupply voltages. This means that the integratedelectronics are supplied with both positive and negativepotentials with reference to ground (0V).

VC = 0, ±12V; 0, ±15V; 0, ±24V; etc.

The new generations of ASIC based transducers operateon a single unipolar supply with reference to ground (0V).

VC = 0 ... +5 V →This option allows the user to save cost by removing theneed for dual supply.

It is important when choosing between the alternativetechnologies to consider the current requirements thattransducers place on their power supplies. Typically, wehave the following current based on the technologyemployed:

Selection parameter 2: Frequency response Selection parameter 2: Frequency response Selection parameter 2: Frequency response Selection parameter 2: Frequency response Selection parameter 2: Frequency response

The amount of board space a component occupies isan important design criteria. LEM has developed aseries of transducers that require only a small area onthe circuit board. They use if possible, the same housingor similar packaging for different current ranges. For theuser, this simplifies the development of a completeproduct series covering several power ranges.

Optimum use of spaceOptimum use of spaceOptimum use of spaceOptimum use of spaceOptimum use of space

The compact design of the ASIC-based LTS, LTSR, LASand new HAIS and HXS series transducers, enable usersto take advantage of the intrinsic benefits of isolated Halleffect-based current measurement - high accuracy, fastresponse, and, wide bandwidth - without the usual trade-off in PCB real estate.

The frequency response for LEM transducers is primarilydependent on the type of transducer, i.e. closed or openloop, etc., since within each type there are a number of keyfactors which fundamentally affect the transducersbandwidth.

For open loop transducers, the core geometry, the numberand thickness of the laminations, and the specific core ma-terial have a direct impact on bandwidth.

In the case of closed loop, Eta and IT-type, (and to a lesserextent, C-type) the coupling between the primary andsecondary - which is affected by the particular coregeometry and construction - is the determining factor intransducer bandwidth.

When for the AV 100 Type and PRiME, it's a question ofelectronic limitation.

In general bandwidth is as follows:

• Open Loop DC to 25/50 kHz *• ETA and IT Type DC to 100 kHz (-1dB)• Closed Loop DC to 200 kHz (-1dB)• C Type DC to 500 kHz (-3dB)• AV 100 Type DC to 13 kHz (-3dB)• PRiME AC 10 Hz to 6 kHz (-3dB)

(typically but can go up to several kHz)

* Note: Small signal bandwidth to avoid excessive coreheating at high frequency.

Working Voltage level allowed by a transducer intended tobe used in an application classified as being "Industrial" isdefined according to several criteria defined under the EN50178 standard. Some are dependent of the transduceritself when the others are linked to the application.

These criteria are the followings:• Clearance distance• Creepage distance• Pollution degree (of the application)• Overvoltage category (of the application)

• Comparative Tracking Index (CTI linked to the kind ofmaterial used for the transducer case) leading to aclassification over different Insulating Material groups

• Simple or Reinforced isolation need.

LEM transducers follow this thought process for theirdesigns. For PCB mounting transducers, the customerPCB tracks layout has to be taken into account to findthe possible working voltage. Indeed, the clearance andcreepage distances can be different according to thecustomer PCB layout.

Quality is requested by everyone and it is quite justified.The levels required by customers can be different according tothe applications. This quality has to be reached but also main-tained in the time and constantly improved as well as forproducts than for services. The different LEM design andproduction centers around the world are either ISO TS 16949,and/or ISO 9001 and/or ISO 14001 certified.

LEM qualityLEM qualityLEM qualityLEM qualityLEM quality

Several quality tools have been implemented in LEM to assessand analyze its performances to be able to take the necessaryactions to remain a responsive player in the market.Among which the most representatives are :

- DPT FMEA (Design Process Tool & Failure Mode Effect Analysis)- Control Plan- Cpk – R&R (Capability for Processes & measurement systems)- QOS – 8D (Quality Operating System – Eight Disciplines)- IPQ (Interactive Purchase Questionnaire).

In addition to these quality programs and since 2002, LEMembraces Six Sigma as its methodology in pursuit of businessexcellence. The main goal is to create an environment in whichanything less than Six Sigma quality is unacceptable.

Selection parameter 7: Output signal Selection parameter 7: Output signal Selection parameter 7: Output signal Selection parameter 7: Output signal Selection parameter 7: Output signal

The key feature of this specific range of products is toprovide outputs suited for interface to process controlsystems. Outputs provide an instantaneous, RMS or TrueRMS signal and could be a voltage (10 V or 5 V) or current(4-20 mA). That allows a direct interface with a PLC, meter,or other instruments. Transducers are available with solidcore or split core package and can be panel fixed or DINrail mounted.

Multiple applicationsMultiple applicationsMultiple applicationsMultiple applicationsMultiple applications

These transducers are particularly well suited for thefollowing applications:- AC or DC motor load control (pump, conveyor, fan,

machine tool,…)- Metering- Remote monitoring- Heater load control- Battery current monitoring- Light control Automated controlling of pumps

LEM transducers are available with different outputsignals, depending on the operation principle and theapplication.

Closed Loop transducers generally provide a currentoutput, proportional to the primary signal. The user canobtain a voltage signal by defining a burden resistorwithin the limits specified in the datasheet.

Open Loop, Eta,CT type and PRiME transducers directlyprovide an amplified voltage signal proportional to theprimary current. In the case of single supply voltage, theoutput signal varies around a nonzero reference.

The process control series offers specific output signalssuited to interface with PLCs, controllers, meters, and otherinstrumentation. The following output options are available:

- Instantaneous voltage or current (4-20 mA)- DC True RMS voltage or current (4-20 mA)

A wide selection of LEM solutions is available forgalvanically isolated voltage measurement, at variouslevels of performance.LEM currently offers two different options for voltagemeasurement:• User specified primary resistor:

The user connects a primary resistor in series with thetransducer. The value of the primary resistor R1 isselected according to the voltage to be measured.This approach allows for maximum flexibility

• Integrated primary resistor:The integrated primary resistor R1 predefines the no-minal measuring voltage of the transducer. LEM offersa wide selection of nominal voltage levels to cover avariety of applications.

Selectable voltage measurementsSelectable voltage measurementsSelectable voltage measurementsSelectable voltage measurementsSelectable voltage measurements

Many applications require the assessment of electricpower, with the combined measurement of LEM voltageand current transducers. Users can control a variety ofsystems, including the lighting of airport runways.

Together with current transducers, voltage transducers are used forcontrolling the brightness of the lights on runways.

LEM transducers are designed and tested according torecognized worldwide standards. Our range of industrialtransducers comply with the following requirements:

EN 50178 is our standard of reference for electrical, envi-ronmental and mechanical parameters. It guarantees theoverall performances of our products in industrialenvironments. All of LEM products are designedaccording to EN 50178

CE marking is a guarantee that the product complies withthe European EMC directive 89/336/EEC and the LowVoltage Directive 73/23/EEC, and therefore warrants the

Electro-Magnetic Compatibility of the transducer and thesafety isolation between primary and secondary. Virtuallythe entire line of LEM transducers carries the CE marking.

UL is used as a reference to define the flammability of thematerials (UL 94-VO), and LEM is currently recognised for main models, and is actively pursuing qualificationof additional models. You can consult the UL website toget the updated list of recognised models www.UL.com.

The individual datasheets specify precisely the applicablestandards & approvals & recognitions for each individualproduct.

Selection parameter 9: Measuring Accuracy Selection parameter 9: Measuring Accuracy Selection parameter 9: Measuring Accuracy Selection parameter 9: Measuring Accuracy Selection parameter 9: Measuring Accuracy

IGBT commutation generates voltage variations withhigh dv/dt levels. These fluctuations may induce errorson the output signal of voltage transducers. LEM hasdeveloped special versions of transducers with a screenbetween the primary and the secondary circuit,significantly reducing the error generated by theseperturbations.

Addressing EMCAddressing EMCAddressing EMCAddressing EMCAddressing EMC

The screen is a standard feature on several series ofvoltage transducers (CV3, AV 100, LV 200-AW/2), and isavailable as an option on LV 100 series.

Multiple package configurationsMultiple package configurationsMultiple package configurationsMultiple package configurationsMultiple package configurationsCustom-tailored solutions for current and voltage measurement.

Accuracy is a fundamental parameter in electrical systems.Selecting the right transducer is often a trade-off betweenseveral parameters: accuracy, frequency response, weight,dimensions, costs... The measuring accuracy for LEMtransducers depends primarily on the operation principle.

Open Loop transducers are calibrated during the manufacturingprocess and typically provide an accuracy better than 2 % ofthe nominal range at 25 °C. For additional offset and gain driftparameter, please refer to individual datasheets.

New ASIC based Open Loop and Eta transducers are beingdeveloped to provide improvement in gain and offset drift overtraditional Open Loop transducers.

Closed Loop current and voltage transducers provide excellentaccuracy at 25 °C, in general below 1 % of the nominal range,and a reduced error over the specified temperature range,thanks to their balanced flux operation.

IT and CT types are high performance transducers withexceptional accuracy level over their operating temperaturerange.

Individual datasheets provide all relevant information toprecisely calculate the overall accuracy of a given transducer ina specific application.
