MCTH400A High-precision Current Sensor 0.01% Accuracy Wideband 100kHz Laboratory-grade Isolation Measurement Applicable To Medical new Energy
1. Basic Parameters
Maximum current: 400A (DC/RMS), accuracy of 0.01%, bandwidth of 100kHz, suitable for DC, AC and irregular waveform measurement.
2. High sensitivity and low loss
Current transfer ratio 1:2000, extremely low insertion loss, noise ≤±0.004μA, suitable for laboratory precision instruments or battery pack monitoring.
3. Core technology support
Adopting excitation flux closed-loop control and temperature control compensation technology, the temperature drift is extremely small, ensuring stable operation in the range of -10℃~+70℃.
4. Safety protection design
Power frequency withstand voltage 5kV, insulation resistance＞2000MΩ@500V, support overload Error signal alarm to ensure equipment safety.
5. Application scenarios
Laboratory current calibration, medical equipment (such as MRI), small industrial motor drive and new energy photovoltaic system.
