Applications

For engineers / R&D specialists:
Suitable for designing three-phase energy metering and power network monitoring systems, especially when using energy meters with 333 mV current inputs. This allows avoiding conventional current transformers and leveraging the advantages of Rogowski coils.

For electricians:
DIN-rail mounting, clearly marked terminals, and standard 12 V DC power supply enable fast and reliable installation in electrical panels, even in space-constrained conditions.

For industrial, energy, and commercial facilities:
Used in manufacturing plants, substations, office buildings, shopping centers, and data centers where accurate three-phase current measurement and reliable compatibility with metering equipment are required.

Advantages

Three-phase solution in a single DIN module
333 mV RMS output – safe and widely supported
Compact DIN-rail mounting
Stable and reliable operation

Limitations

Fixed rated current
AC current measurement only
Requires external 12 V DC power supply
