Product Details
CSNS300M-001 Current Sensor For Servo Systems High-voltage
Frequency Converters
Application:
Mainly used for current measurement and monitoring, applicable to
various speed drives, servo systems, overcurrent protection
devices, ground fault detectors, robots, power supplies,
wattmeters, etc. It is also widely used in fields such as wind
energy and solar energy, high-voltage frequency converters,
electrochemical metallurgy, new energy vehicles, etc., helping to
achieve precise current detection and control to ensure the safe
and stable operation of the system.
Features:
- High precision: Accuracy is better than ±0.5%, enabling accurate
current measurement to help improve power conversion efficiency.
- Fast response: Response time is less than 500ns, which can quickly
react to current changes and provide timely current feedback.
- Good linearity: Linearity is better than ±0.1%, with an excellent
linear relationship between output and input current, making
measurement results more reliable.
- Strong anti-interference ability: With excellent electromagnetic
compatibility (EMC), it can withstand complex electromagnetic
interference environments to ensure measurement accuracy.
- Good electrical isolation: Primary and secondary electrical
insulation can reach 6kV rms/50Hz/1 minute, effectively isolating
the primary and secondary circuits to ensure the safety of
equipment and personnel.
- Good temperature stability: Small temperature drift, less affected
by temperature changes, and can work stably in the industrial
temperature range of -40°C to +85°C.
- Wide measurement range: Rated current is 300A.t rms, and the
measurement range can reach 0 to ±600A.t, meeting various current
measurement needs.
