It can be used for measuring AC,DC,pulsed and mixed current. Electrical characteristics Type RTNT400-s Primary nominal input current 400 A Ip Measuring range of primary current 0~±800 A Isn Secondary nominal output current 200 mA kn Conversion ratio 1:2000 rm Measuring resistance (VC=±12V) Ip=±200A: 0-150 a Vc Supply voltage ±12~±18(±5%) V Ic Current consumption VC=±12V 30+Is mA Vd Insulation voltage AC/50Hz/1min 6 kV l Linearity <0.1 %FS X Accuracy TA=25C VC =t15V <±1 % Io Zero offset current TA=25C <±0.25 mA Iom Residual current Ip^0 <±0.15 mA Iot Thermal drift of I0 Ip=0 Ta=-25~+85C <±0.5 mA Tr Response time <1 f Frequency bandwidth(-1dB) DC~100 kHz Ta Ambient operating temperature -25~+70 C Ts Ambient storage temperature -40~+80 C Rs Secondary coil resistance(TA=25C) 30 a Standard Q/3201CHGL02-2007 Dimensions of drawing (mm) Connection Remarks 飕Incorrect connection may lead to the damage of the sensor. Isn is positive when the Ip flows in the direction of the arrow. Dynamic performance (di/dt and response time) are best with a primary bar in the center of the through-hole.
