  • Product description
    Single-Phase 5A Integrator for Rogowski Coils | 24VDC | 35mm DIN Rail | 30Hz-2kHz

    Single-Phase 5A Integrator for Rogowski Coils | 24VDC Power Supply | Dynamic Transducer for Traditional Meters

    The Single-Phase 5A Integrator for Rogowski Coils is a professional device that converts the signal from a flexible Rogowski coil into a standard 0–5A AC current output. Designed for 35 mm DIN rail mounting and powered by a 24VDC source, this integrator enables easy integration of flexible Rogowski coils with traditional energy metering systems, measuring instruments, or power analyzers, bypassing the limitations of traditional current transformers (CTs).

    A Flexible Alternative to Traditional Current Transformers

    The device features a wide bandwidth (30Hz to 2kHz), Class 0.5 accuracy, and excellent linearity (±0.2%). Combined with a Rogowski coil, it forms a versatile system for measuring high currents (from 50A up to 20kA) and integrating them with existing energy meters.

    Design and System Elements

    Component Specification / Features Role in Engineering System
    Integrator Module Dimensions: 112 × 95 × 22.5 mm, weight 170g Mounted on a 35mm DIN rail; processes and integrates the coil signal.
    Recommended Rogowski Coil Inner diameter: 100 mm, sensitivity: 100mV/kA @ 50Hz Flexible primary sensor placed around conductors to measure high currents.
    Power Supply DC 24V (1A or more, power ≤15W) Ensures stable operation of the integrator's microchips and internal circuitry.
    Output Circuit 0 ~ 5A AC (max. 5.5A AC short-term) Connects directly to traditional energy meters or secondary measurement devices.

    How Does the Rogowski Coil and Integrator System Work?

    1. The flexible Rogowski coil is wrapped around the conductor carrying an AC current (from 50A to 20kA).
    2. The coil generates a low-voltage signal proportional to the rate of change of the current.
    3. This signal is fed into the 24VDC-powered integrator, which performs mathematical integration to reconstruct the primary current waveform.
    4. The integrator outputs a standard alternating current signal (0 ~ 5A AC), easily readable by traditional meters and power analyzers.
    5. The wide measurement bandwidth (30Hz – 2.2kHz) ensures accurate signal reconstruction even in the presence of harmonic distortions.
    Important Safety Rules and Installation Requirements

    The device must only be installed by qualified electricians with proper certification. After installation, the Rogowski coil may surround exposed parts with dangerous voltages; therefore, a protective cover or additional insulating barrier must be installed around it. It is strictly forbidden to severely bend, pull, puncture, or tightly strap the coil with cable ties while bent!

    Pros / Advantages

    • Legacy Equipment Compatibility: Allows flexible Rogowski coils to connect directly to standard 5A energy meters.
    • Wide Measurement Range: Efficiently processes currents from 50A up to 20kA.
    • High Accuracy: Class 0.5 accuracy and excellent linearity (±0.2%) guarantee reliable metering data.
    • Simple Installation: Compact 22.5 mm wide enclosure mounts directly on a DIN rail.
    • Wide Frequency Bandwidth: Measurements from 30Hz to 2kHz maintain precision even in distorted grid conditions.

    Cons / Limitations

    • External Power Required: The device strictly requires a stable 24VDC (1A) power supply.
    • Mechanical Constraints on Coils: Rogowski coils cannot be sharply bent, pulled, or tightly strapped with cable ties in a deformed state.

    Who is it suitable for? (Applications)

    • Industrial energy monitoring and power analysis equipment
    • Retrofitting and adapting legacy energy meters for flexible Rogowski coils
    • High-current measurement systems in switchgear and substations
    • Electricity metering in manufacturing processes

    Who is it NOT suitable for?

    • Residential or low-current measurements (where currents are below 50A)
    • Direct outdoor installation without an additional IP-rated protective enclosure (device rating is IP20)

    Practical Example

    During a factory energy management system upgrade, the main incoming feed carries an AC current up to 3000A. A flexible Rogowski coil is installed around the busbars/cables, and its output is connected to this 5A integrator mounted on a DIN rail. The integrator converts the signal into a standard 0-5A AC signal compatible with an existing legacy energy meter or panel meter, avoiding the expensive replacement of heavy traditional current transformers.

    Frequently Asked Questions (FAQ)

    What power supply voltage is required for the integrator?

    The device operates on 24VDC (1A or higher recommended, power 20W+).

    Which coil is recommended for use with this integrator?

    It works best with a Rogowski coil having a 100mm diameter and a sensitivity of 100mV/kA @ 50Hz.

    How is the integrator mounted?

    The device is designed for installation on a standard 35 mm DIN rail.

    What is the output current?

    The rated output current is 0 ~ 5A AC (with a short-term maximum overload up to 5.5A AC).

    Installer's Note

    When mounting the integrator on a DIN rail, ensure adequate ventilation and do not block the enclosure's cooling vents. Handle the Rogowski coil with care: do not bend it around sharp corners, pull it, or compress it with cable ties in a deformed state to maintain its accuracy class.

    The Single-Phase 5A Integrator for Rogowski Coils is a reliable and precise tool bridging modern flexible coil technology with traditional 5A current measurement systems.
