Description :

Current Transducer LAX SERIES IPN = 16 – 100 A Ref: LAX 100-NP For the electronic measurement of currents: DC, AC, pulsed …. , with a galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit). Maxi. 16.5 mm Features • Closed loop (compensated) current transducer using the hall effect • Printed circuit board mounting • Isolated plastic case recognized according to UL 94-V0 • Multirange with a single device: 16, 25, 33, 50 and 100 A rms • 3 independent primary jumpers. Applications • AC variable speed drives and servo motor drives • Static converters for DC motor drives • Battery supplied applications • Uninterruptible Power Supplies (UPS) • Switched Mode Power Supplies (SMPS) • Power supplies for welding applications. Advantages • Excellent accuracy • Very good linearity • Low temperature drift • Optimized response time • Wide frequency bandwidth • No insertion losses • High immunity to external interference • Current overload capability • Height less than 16.5 mm for a simplified integration with power modules • Low primary inductance. Standards • EN 50178 • UL508 – UR marking • IEC 61010-1-safety. Application Domain • Industrial. 070615/8 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice.
