Rated Input (Ipn): 10-1000 A
Measurement Range (Ip): 2500 A
Turns Ratio: 1:5000
Supply Voltage: ±15 to ±24 V
Power Consumption: ≤20+Ip/Ns mA
Offset Current: ≤±0.2 mA
Response Time: <1 μs
Linearity: ≤0.1 %FS
Galvanic Isolation: 6 KV
Bandwidth: DC to 150 KHz

Applications: The sensor is suitable for variable speed drives, welding machines, battery-supplied applications, uninterruptible power supplies (UPS), and electrochemical applications.

Standards: The product complies with UL94-V0, EN60947-1:2004, IEC60950-1:2001, EN50178:1998, and SJ 20790-2000 standards.

General Data:

Operating Temperature: -40 to +85 ºC
Storage Temperature: -40 to +125 ºC
Mass: Approximately 600 g

Mechanical Dimensions: All dimensions are in mm with a general tolerance of ±1.0mm.

Directions for Use:

The output current (Is) flows forward when the input current (Ip) follows the arrowhead direction.
The primary conductor should not exceed 120℃.
Optimal dynamic performance is achieved when the primary hole is fully filled with the bus bar.
Primary turns should be at the top of the sensor for optimal magnetic coupling.
Voltage is measured at the output end when current passes through the sensor.
Custom designs are available for different rated input and output currents.

Characteristics Chart: The document includes charts illustrating pulse current signal response characteristics and effects of impulse noise.
