MCTH2000A High precision current sensor 2000A Current Monitor | 5kV Withstand Voltage, 1:2000 Ratio, Overload Alarm For Power Applications
1.Ultra-large current precision measurement
Maximum measurement current 2000A (DC/RMS), accuracy 0.01%, bandwidth 50kHz, supports DC, AC and irregular waveforms, suitable for high-power industrial scenarios.
2.Core technology guarantees stability
Adopting excitation flux closed-loop control and multi-point zero flux technology, combined with temperature control compensation, temperature drift ≤±0.004μA, ensuring stable operation in -10℃~+70℃ environment.
3.Low loss and high safety
Current transmission ratio 1:2000, load resistance ≤4Ω (@2000A), extremely low insertion loss; power frequency withstand voltage 5kV, insulation resistance＞2000MΩ@500V, support overload alarm (Error signal).
4.Wide range of industrial compatibility
Applicable to ship power drive, new energy inverter (photovoltaic/wind power), smart grid medium and low voltage substation and industrial motor drive system.
5.Flexible power supply adaptation
Optional ±24V dedicated power supply (such as MCTP5724VA) supports multi-channel power supply, output current 0~1.5A/channel, meeting the needs of complex system integration.
