CTSR 1-P Lem

Current Transducer CTSR 1-P I = 1A PRN For the electronic measurement of current: DC, AC, pulsed..., with galvanic isolation between the primary (high power) and the secondary circuit (electronic circuit). Features Applications Closed loop (compensated) current transducer Residual current measurement Voltage output Leakage current measurement in transformerless PV Single supply voltage inverters Isolated plastic case material recognized First human contact protection of PV arrays according to UL 94-V0 Failure detection in power sources PCB mounting Symmetrical fault detection (e.g. after motor inverter) Leakage current detection in stacked DC sources Single phase or three phase nominal current measurement Advantages up to 30 A per wire (DC or AC) High accuracy Standards Very low offset drift over temperature Wide aperture (20.1 mm) EN 50178 High overload capability IEC 61010-1 (safety) High isolation capability Application Domain Reference pin with two modes, Ref In and Ref Out Industrial Degauss and test functions Suitable to fulfil VDE 0126-1-1 and UL 1741 Page 1/7 28Mar2012 / Version 2 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice. www.lem.com CTSR 1P Absolute maximum ratings Parameter Symbol Unit Value Supply voltage V V 7 C Primary conductor temperature C 110 Impulse overload (100 s, 500 A/s) A 3300 Stresses above these ratings may cause permanent damage. Exposure to absolute maximum ratings for extended periods may degrade reliability.
