| Current Transducer HNC-300P 300A-100mA For the electronic measurement of currents: DC, AC, pulsed, mixed, with a galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit). IPN = 300 A Electrical data IPN IP VC IC Vd R IS IOUT RL Primary nominal r.m.s. current Primary current measuring range Supply voltage ( 5 %) Current consumption R.m.s. voltage for AC isolation test, 50Hz, 1mn Isolation resistance @ 500 VDC Output current @ IPN, R L = 40 , TA = 25C Load resistance 300 600 15 2.5 > 500 100 40 A A V kV M mA Features * Hall effect measuring principle * Galvanic isolation between primary and secondary circuit 15mA+(IPN/3000)mA * Low power consumption * Insulated plastic case recognized according to UL 94-V0 Accuracy-Dynamic performance data Advantages < 1 % of IPN < 0.25% of IPN < 0.5 mA < 0.3 mA/K < 0.005 mA/K < 0.04 %/K <1 s X L IOE IOH IOT TC G tr Accuracy @ IPN, TA = 25C (without offset) Linearity error 1) (0 .. IPN) Electrical offset current @ TA = 25C Hysteresis offset current @ IP = 0; after an excursion of 1 x IPN Thermal drift of IO @ TA = - 5 .. + 70 C Thermal drift of the gain (% of reading), TA = -5..+70C Response time @ 90% of IP * Easy installation. * Small size and space saving * Only one design for wide current ratings range * High immunity to external interference General data TA TS m Ambient operating temperature Ambient storage temperature Mass - 10 .. + 80 - 15 .. + 85 140 C C g Applications * DC motor drives * Switched Mode Power Supplies (SMPS) * AC variable speed drives * Uninterruptible Power Supplies (UPS) * Battery supplied applications * Power supplies for welding applications Application Domain * Industrial Notes : 1) Linearity data exclude the electrical offset. 060609/1 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice. Page 1/2 LEM www.lem.com Dimensions HNC-300P 300A-100mA (in mm. 1 mm = 0.0394 inch) Current direction 5 & 6 : N.C. Mechanical characteristics * General tolerance ( " " appended numbers) 0.5 mm 1 mm Safety This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the following 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 built-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. 060609/1 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
