LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice. www.lem.com18october2011/2 HC2F100-SN CLIPS Sensitivity: The Transducer’s sensitivity G is the slope of the straight line Vout = f (IP), it must establish the relation: Vout (IP) = VC/5 (G x IP + 2.5) (*) (*) For all symetrics transducers. Offset with temperature: The error of the offset in the operating temperature is the variation of the offset in the temperature considered with the initial offset at 25°C. The offset variation I OT is a maximum variation the offset in the temperature range: IOT = IOE max - IOE min The Offset drift TCIOEAV is the IOT value divided by the temperature range. Sensitivity with temperature: The error of the sensitivity in the operating temperature is the relative variation of sensitivity with the temperature considered with the initial offset at 25°C. The sensitivity variation G T is the maximum variation (in ppm or %) of the sensitivity in the temperature range: GT = (Sensitivity max - Sensitivity min) / Sensitivity at 25°C. The sensitivity drift TCGAV is the G T value divided by the temperature range. Offset voltage @ IP = 0 A: Is the output voltage when the primary current is null. The ideal value of VO is V C/2 at V C = 5 V. So, the difference of VO -VC/2 is called the total offset voltage error. This offset error can be attributed to the electrical offset (due to the resolution of the ASIC quiescent voltage trimming), the magnetic offset, the thermal drift and the thermal hysteresis. Environmental test specifications Output noise voltage: The output voltage noise is the result of the noise floor of the Hall elements and the linear I C amplifier gain. Magnetic offset: The magnetic offset is the consequence of an over-current on the primary side. It’s defined after an excursion of I P max. Linearity: The maximum positive or negative discrepancy with a reference straight line VOUT = f (IP). Unit: linearity (%) expressed with full scale of IP max. Response time (delay time) tr: The time between the primary current signal and the output signal reach at 90 % of its final value Typical: Theorical value or usual accuracy recorded during the production.
