This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturer’s operating instructions. Caution, risk of electrical shock When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary busbar, power supply). Ignoring this warning can lead to injury and/or cause serious damage. This transducer is a build-in device, whose conducting parts must be inaccessible after installation.A protective housing or additional shield could be used. Main supply must be able to be disconnected. 5November2014/Version 17 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice www.lem.com Dimensions HASS 50 .. 600-S (in mm) 22.8 16 Connection Terminal pin1: Terminal pin 2: Terminal pin 3: Terminal pin 4: d4.5 10.4 2.5 20 R5.2 Vref (IN/OUT) Output 0V +5 V Ip 4.8 3 1 4 Molex 5 d2.5 Required connection circuit Terminal Pin 1 Vref(IN/OUT) 2 Output 3 0V 4 +5V V (IN/OUT) ref 1...Vref(IN/OUT) Output R =10Kohm L 0V 2...OUTPUT +5V 3...0V 4...+5V Operation principle +UC Vout Vref (IN/OUT) 0V 5November2014/Version 17 5 20 40 +/-0.5 HASS 9.8 R0.5 10.4 30 +/-0.5 20.4 Mechanical characteristics ●● ●● ●● ●● ●● General tolerance Aperture for primary conductor Transducer fastening Recommended fastening torque Connection of secondary Remarks ±0.5 mm 20.4 × 10.4 × 0.5 mm M4 <1.5 N·m Molex 5045-04A ●● IS is positive when IP flows in the direction of the arrow. ●● Temperature of the primary conductor should not exceed 120 °C. ●● This is a standard model.
