LEM has introduced the HAIS series of PCB-mounted current transducers, designed to operate from a single +5 V power supply. The transducers are available with rms ratings of 50 A/100 A/150 A/ 200 A/400 A, with a measuring span of up to ±3 x IPN. The aperture accepts bus bars as large as 8 x 15 mm, in a very compact design measuring only 33 x 29 x 14 mm.
The heart of the HAIS series is a LEM ASIC that offers a number of performance improvements, in particular, a more extended operating temperature range (-40 to +85°C) compared to traditional discrete technology.
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 extra pin to enable it to be fed to the reference of an A/D converter or a DSP, for example. The user can also apply the system's voltage reference (between 2 and 2,8 V) to the extra pin (Ref), to produce an output offset that is equal to the external reference. This mode can be used to cancel the reference thermal drift.
An optional bus bar (HAIS xx-TP models) is available for nominal ratings of 50 A and 100 A. The transducers are CE marked, conform to the EN 50178 standard and are recognised for industrial applications.
