Laboratory Rogowski Coil Integrator | High Precision | 3000 A | 85 mV/kA | 0–10 V DC | For AC Current Measurement | S1.2

Technical Specifications

Type: Laboratory-grade Rogowski coil integrator (high precision)
Model: S1.2
Rated input current: 3000 A
Output signal: 0–10 V DC
Coil transfer ratio: 85 mV/kA 
Measurement accuracy: ±0.2%
Frequency bandwidth: 5 Hz – 20 kHz
Power supply: 4–12 V DC (default) or 24 V DC
Measurement type: AC current only
Design note: For each 100 A of rated current, the maximum output is 1 V
Mounting: Fixed (laboratory / test bench type)

Functions

High-precision Rogowski signal integration
Direct 0–10 V DC output – compatible with most measurement and control systems
Wide frequency range – suitable for harmonic and fast dynamic process analysis
Stable and linear signal across the entire operating range
Adaptable to different Rogowski coils

Applications

Engineer / R&D specialist: Suitable for testing power electronics, inverters, converters, UPS systems, and electric drives where precise monitoring of current amplitude and dynamic changes is required. The 0–10 V DC output allows easy integration into measurement systems without additional converters.

Electrical and measurement laboratories: With ±0.2% accuracy and wide frequency bandwidth, the S1.2 is ideal for reference, comparative, and calibration measurements where repeatability is critical.

Industrial engineering (high requirements): Used in complex projects where standard industrial integrators do not provide sufficient accuracy, such as power quality, harmonic, or high-current analysis.

Advantages

Very high accuracy – ±0.2%
Stable 0–10 V DC output
Wide frequency bandwidth (up to 20 kHz)
Suitable for professional testing and laboratory work

Disadvantages

Fixed rated current – must be selected before ordering
Designed for AC current measurement only
Not a DIN-rail solution (laboratory-oriented)
Requires an external DC power supply
