MASTEK MCTL500A 500A Precision Current Sensor, 100KHz Bandwidth for Renewable Energy & Grid Monitoring
High-Power Measurement: 500A DC/AC range with 0.1% linearity error, optimized for solar inverters and battery storage systems.
Enhanced Stability: Temperature-controlled compensation technology minimizes drift (±0.004μA offset) across -10°C to +70°C.
Low Load Resistance: ≤4Ω load resistance reduces energy loss during high-current operations.
Industrial Safety: 5KV insulation voltage and UL94-V0 flame-retardant housing ensure reliability in harsh environments.
Multi-Industry Application: Widely used in rail transit, medical MRI, and marine propulsion systems.
