Functions

Three-phase Rogowski signal integration
4–20 mA output – industrial standard for long cable runs
High immunity to electromagnetic interference
Stable and linear signal over the entire operating range
Compact DIN-rail solution for professional installation

Applications

For engineers / R&D specialists: Ideal choice for PLC, SCADA, BMS, and industrial control system projects where a reliable 4–20 mA current signal is required for three-phase current monitoring.
For electricians/installers: DIN-rail mounting, clearly marked terminals, and standard 12 V DC supply allow quick and safe installation in electrical panels, even in limited space.
For industrial, energy, and commercial facilities: Used in production plants, distribution boards, substations, office buildings, and shopping centers where reliable three-phase current measurement and stable signal transmission to a central control system are required.

Advantages

Three-phase solution in a single DIN module
4–20 mA output resistant to interference
Compact and orderly installation
Stable operation in industrial environments

Limitations

Fixed rated current
Designed for AC current measurement only
Requires external 12 V DC power supply
Not suitable for high-frequency laboratory measurements
