Product Description AdvantagesCFB600ITN15D400For ultra-high precision measurement of current: DC, AC, pulsed...,with galvanic separation between primary and secondary.Advantages- Very high accuracy- Easy installation- Extremely low temperature drift- Wide frequency bandwidth- High immunity to external fields- Very good linearity- No insertion losses- Low noise on output signal- Low noise feedback to primary conductor.Feature- Closed loop (compensated) current transducer using an extremely accurate zero flux detector- Electrostatic shield between primary and secondary circuit- Status signal to indicate the transducer state- LED indicator confirms normal operationApplications- Metrological verification and calibration- Commercial measure- Instrumentation (like power analyzer)- Laboratory current measuremen- Battery pack detection- Medical devices (MRI)- Power supply- Electrical power control- New energy- Ships and warships- Rail transitSpecificationElectrical data (Ta=25oC,Vc= ±15VDC) RefParameterSymbolCFB600ITN15D400UnitPrimary side rated inputI PN DC± 600APrimary side rated AC inputI PN424APrimary side max inputI PM110% IPN DC <IPM<120% IPN DCATurns ratioN p / N S1 : 1500TOutput current rmsI S± 400 * I P / I PNmASecondary coil resistanceR S11ΩMeasuring resistanceR M0-10 ΩΩSupply voltageV C± 15V (± 5%)VAccuracyX G@DC , T =25°C <10 ppm%Offset currentI OE@ I P =0 , T =25°C < ±15 ppmmATemperature coefficient ofI OE@ I P =0 , 10 ~ +50°C < ±0.5 ppm/K Offset stability 0.8 ppm/month Linearity errorεr<1.5 ppm%FSDi/dt accurately followed > 100A/μsResponse time tra @90% of I PN < 1.0μsWorking status descriptionAfter the equipment is powered on, the green indicator light is always on when the equipment works normallyWhen the current is overloaded or the power supply is abnormal, the green light is offWhen the green light is not on, you should first check whether the power supply of the sensor is normal.When the power supply is normal, if the green indicator is off, the current sensor is in a non-zero flux state. If theprimary current at this time exceeds the specified range of the sensor, the sensor enters the overload operation mode.When this happens, the transducer will shut down the measuring circuit and wait until the primary current is near zero.Interlock port wiringDimension1.
