Product Description

D1 Industrial Integrator Overview

The D1 is an industrial Rogowski coil integrator designed for installation in distribution boxes. Housed in a plastic 1-module DIN-RAIL enclosure, it is powered directly from the mains and provides essential signal processing for flexible current sensors.

Core Functions

Amplifies weak mV signals from Rogowski coils to standard signals for multimeters and scopes.
Ensures signal equalization for a linear response across wide frequency ranges.
Shifts the output signal by 90° to accurately represent the measured current.

Key Advantages

High read accuracy: 0.5%
DIN-RAIL mounting for easy installation
Wide bandwidth: 5Hz to 20kHz
Extremely low zero drift (down to 2mV)

Main Applications

Power monitoring & analysis
Harmonics and transients monitoring
Welding machine control
High current measurement & PLC control

Understanding Rogowski Coil Technology

Rogowski coils are air-cored toroidal coils placed around a conductor. The magnetic field produced by the AC current induces a voltage in the coil proportional to the rate of change of the current. When combined with the D1 integrator, it provides a highly accurate measurement system with no saturation risk.

Frequently Asked Questions

Q: What is the primary purpose of the D1 Industrial Integrator?

A: The D1 integrator is designed to amplify and convert the weak mV signals from Rogowski coils into standard signals (like 4-20mA or 0-5V) that can be easily read by industrial controllers and monitoring devices.

Q: Can this integrator be used with different sizes of Rogowski coils?

A: Yes, the D1 can be combined with various models and sizes of Rogowski coils, including Y-FCT, NRC, and MRC series, making it a highly flexible solution.

Q: What are the available output signal options?

A: The D1 series offers three standard output versions: D1.1 (5V AC rms), D1.2 (4V DC true-rms), and D1.3 (4-20mA). Custom values are available upon request.

Q: Is the device suitable for high-current monitoring?

A: Absolutely. It supports rated inputs from 100A up to 6000A and is used in applications involving currents as high as 1500kA in pulse welding machines.

Q: How is the D1 integrator installed?

A: It features a compact 1-module DIN-RAIL enclosure, making it extremely easy to install within standard industrial distribution boxes.

Q: Does it work with DC components?

A: While it does not measure pure DC, it can carry out accurate measurements of AC components even with a large superimposed DC component, as there is no iron core to cause saturation.
