Mastek MCTH200A 200A High-Accuracy Current Sensor 0.01% Error Rate For Wind Energy , EVs & Missile Systems
High-Current Measurement:Supports up to 200A DC/AC with 1:2000 current ratio, ideal for EV charging stations and missile testing.
Temperature Stability:Advanced thermal compensation ensures ±0.004μA offset drift across -10°C to +70°C.
Wide Bandwidth:100KHz bandwidth captures high-frequency signals in wind turbine inverters and power analyzers.
Low Power Loss:Minimal insertion loss (<0.01%) maximizes efficiency in energy-critical systems.
Safety Assurance:5KV isolation voltage and error signal output protect against overloads in naval or aerospace setups.
