Measurement Range (Ip): Corresponds to the rated input current, ranging from ±15A to ±100A.
Rated Output Voltage: ±2.0±1% V at ±Ipn.
Zero Voltage: 2.5±1% V at Ip=0.
Supply Voltage: +5±5% V.
Power Consumption: ≤10 mA.
Zero Offset Voltage: ≤±20 mV.
Magnetic Offset Voltage: ±15 to ±10 mV.
Offset Voltage Drift: ≤±1.2 to ≤±1 mV/°C.
Output Voltage Drift: ≤±1.2 to ≤±1 mV/°C.
Linearity: ≤1 %FS at Ip=0-±Ipn.
Response Time: ≤0.5 μs at 50A/μs, 10%-90%.
Galvanic Isolation: 2.5 KV at 50Hz, AC, 1min.

Applications: Suitable for AC variable speed drives, static converters for DC motor drives, variable speed drives, welding power supplies, battery-supplied applications, uninterruptible power supplies (UPS), and switched mode power supplies (SMPS).

Mechanical Dimensions: All dimensions are in mm with a general tolerance of ±1mm.
