MCTH1000A UL94-V0 certified current sensor 1000A/0.01% accuracy Multi-level range automatic switching Smart grid/high-speed rail/aerospace applications
1. Ultra-large current measurement
Maximum current 1000A (DC/RMS), accuracy 0.01%, bandwidth 100kHz,
meeting the needs of power systems and heavy industry.
2. High output capacity
Current transfer ratio 1:2000, rated output 0~500mA, can directly
drive high-load instruments or remote monitoring systems.
3. Strong environmental adaptability
The housing complies with the UL94-V0 flame retardant standard,
corrosion-resistant and dust-proof design, suitable for harsh
environments such as steel smelting and chemical industry.
4. Multi-level range switching
Automatic switching technology realizes 400A~1000A wide range
measurement, avoiding manual adjustment and improving efficiency.
5. Typical scenarios
Smart grid power generation monitoring, high-speed train traction
system, satellite power management and nuclear magnetic resonance
equipment current control.
