Rogowski coil integrator for DIN rail | 3000 A | 85 mV/kA | 4–20 mA | For AC current measurement | D1.3

Technical specifications

Type: Rogowski coil integrator with 4–20 mA output
Model: D1.3
Mounting: DIN rail (35 mm)
Rated input current: 3000 A
Output signal: 4–20 mA
Coil transfer ratio: 85 mV/kA
Measurement accuracy: ±1% (from 1% to 100% of rated current)
Frequency bandwidth: 5 Hz – 20 kHz
Power supply: 12 V DC or 24 V DC (default – 24 V DC)
Measurement type: AC current only
Design note: The integrator is selected for a specific configuration (rated current and coil coefficient are not adjustable)

Functions

Integration of the Rogowski coil signal into a stable 4–20 mA output
High immunity to electromagnetic interference
Reliable operation over long cable runs
Clear and standardized interface with automation equipment
Neat, professional installation in electrical panels

Applications

Home / advanced user: Used for accurate monitoring of high currents (e.g. main supply or solar power generation) via home automation or energy monitoring systems.

Electrician: DIN rail format, clearly arranged terminals, and standard 24 V DC power supply allow fast and error-free installation. An excellent choice for upgrading older switchboards where space is limited and reliability is critical.

Engineer / automation specialist: Used in projects requiring a stable analog signal and high resistance to interference. The 20 kHz bandwidth enables monitoring not only the fundamental current but also higher-order harmonics important for power quality analysis.

Advantages

4–20 mA output – industrial standard, resistant to interference
DIN rail mounting – tidy and professional installation
High measurement accuracy across the entire range
Suitable for long-term continuous industrial operation

Disadvantages

Fixed rated current – must be selected accurately
No digital interfaces (RS485 / Modbus)
AC current measurement only
Requires an external DC power supply
