PCB-mounted current measurement transducers
May 2005
Sensors & Transducers
LEM is offering its HAIS series of PCB-mounted current measuring transducers that operate from a single +5 V supply. Ratings RMS are 50, 100, 150, 200 and 400 A, with a measuring span of up to ±3 x IPN. The transducer aperture accepts bus bars as large as 8 x 15 mm, in a compact design of only 33 x 29 x 14 mm. The heart of the HAIS series is a LEM ASIC, which provides a number of performance improvements, in particular an extended operating temperature range (-40 to +85°C).
With the standard HAIS, the internal reference voltage of the ASIC is used to provide a fixed output offset of +2,5 V. This voltage reference is also made available on an external pin to allow it to be fed to the reference of an A/D converter or a DSP.
The SP1 version provides a ratiometric output offset Vcc/2 when the Ref pin is not used. The user can also apply the system's voltage reference (between 2,3 V and 2,7 V) to the Ref pin, in which case the output offset is equal to the external reference. This mode allows reference thermal drift to be cancelled. An optional bus bar (HAIS xx-TP models) is available for nominal ratings of 50 A and 100 A. CE marked and conforming to the EN 50178 standard, these transducers are designed for industrial applications. LEM Components offers a five-year warranty for each transducer.
