产品介绍： |
We have added the HXS series to the range of current transducer families designed to operate from a single +5V power supply. The new PCB-mounting units measure only 18.5 x 16.5 x 10mm and integrates a multi-range primary conductor. The pin-out on the primary conductor allows the HXS 20-NP to be configured as a 5, 10 or 20A RMS nominal model and the HXS 50-NP to be configured as a 12.5, 25 or 50A RMS nominal model, with a measuring span of up to +/-3x IPN. The same pin-out is used for both in order to be able to use the same model for a complete range of drives that use the same control PCB. The internal reference voltage (2.5V) is provided on a separate PIN or can be replaced by an external reference (between 2 and 2.8V) for reference thermal drift cancellation. With a fixed gain and offset the output can be measured precisely to +/- 0.625V at IPN when the reference is used. A unique LEM ASIC designed for use with open-loop Hall effect technology has been incorporated to provide performance improvements, including better offset and gain drifts and linearity, in addition to an extended operating temperature range (-40 to +85C and even +105C with SP2 models) compared with traditional discrete technology. In a three-phase system, a special model (HXS 20-NP/SP3) configured for differential measurement can recreate the third phase current from the other two phase currents. In addition, the HXS 20-NP/SP30 is available for applications when heating due to frequency occurs. The transducers are CE marked, conform to the EN50178 standard and are recognized for industrial applications.
