Product Details
CSNS200M-002S Closed - loop Hall Effect Current Sensor For
Industrial Control Equipment Automotive Electronics
Core Features:
- Versatile Measurement Capability: It can reliably measure DC, AC,
and pulse currents, adapting to diverse current detection scenarios
in industrial and electronic systems.
- High Precision and Stability: With linearity better than ±0.20% and
low offset current drift, it maintains accurate measurement results
even when the temperature changes within the operating range.
- Fast Response and Wide Bandwidth: The response time is less than
500ns and the bandwidth covers DC to 150kHz, which can keep up with
the rapid changes of high - speed pulse currents and meet the
requirements of high - speed current detection.
- Excellent Electrical Isolation: The electrical insulation design
between the primary and secondary circuits enhances the safety of
the sensor in high - voltage application scenarios and avoids
mutual interference between circuits.
- Strong Environmental Adaptability: It can work stably in the
temperature range of - 40℃ to 85℃, suitable for harsh industrial
environments and automotive working conditions.
Typical Applications:
- Industrial Control Equipment: Variable - speed drive devices, servo
motors, welding equipment power supplies, UPS (Uninterruptible
Power Supply), and telecommunications power supply systems.
- Automotive Electronics: Battery management systems, which are used
to monitor the charging and discharging current of automotive
batteries to ensure the stable operation of the power system.
- Protection & Detection Devices: Over - current protection circuits
and ground fault detectors, providing rapid current monitoring
signals for equipment safety protection.
- Robotics & Automation: Current detection in robotic motion control
systems, ensuring precise control of motor operations.
