Measurement Range (Ip): Up to 600 A with specific voltage and resistance configurations.
Turns Ratio: 1:1000 for most models, 1:2000 for RTC200P3.
Supply Voltage: ±12 to ±18 V.
Power Consumption: ≤40+3XIp(Np/Ns) mA.
Offset Current: ≤±0.1 mA at Ip=0.
Linearity: ≤0.1 %FS.
Galvanic Isolation: 3 KV at 50Hz, AC, 1 minute.
Response Time: Less than 0.5 μs at 100A/μs, 10%-90%.
Bandwidth: DC to 250 KHz.

Applications: Suitable for variable speed drives, welding machines, battery applications, UPS, and electrochemical processes.

Standards Compliance: UL94-V0, EN60947-1:2004, IEC60950-1:2001, EN50178:1998, SJ 20790-2000.

General Data:

Operating Temperature: -40 to +85 ºC.
Storage Temperature: -40 to +125 ºC.
Mass: Approximately 50 g.

Mechanical Dimensions: Provided for reference with a general tolerance of ±0.1mm.

Usage Directions:

Current flows in the forward direction as indicated by the arrowhead.
Primary conductor temperature should not exceed 120℃.
Optimal dynamic performance is achieved when the primary hole is fully filled with the bus bar.

Characteristics Charts: Includes pulse current signal response and effects of impulse noise.
