MCTH500A Industrial-grade Anti-interference Current Sensor 500A/0.01% Accuracy Compact Design Suitable For Rail Transit/UPS/welding Equipment
1. Performance upgrade
Maximum current 500A (DC/RMS), accuracy 0.01%, bandwidth 100kHz, support high dynamic response (di/dt ≥ 100A/μs).
2. Output adaptability
Current transfer ratio 1:2000, rated output current 0~250mA, can be directly connected to power analyzer or data acquisition system.
3. Anti-interference ability
Fully isolated design of primary and secondary sides, strong anti-electromagnetic interference ability, suitable for complex electromagnetic environments such as inverters and UPS.
4. Compact structure
Disc-type mounting hole design (4×Φ5mm), weight only ±600g, easy to integrate into rail transit or robot control cabinet.
5. Typical applications
Medium and low voltage substation monitoring, welding equipment current control, elevator drive system and tram power management.
