Functions

Three-phase Rogowski signal integration
1 A RMS output – compatible with conventional protection and measurement systems
High measurement stability across the entire operating range
Safer measurement compared to classic CTs (no open secondary circuit risk)
Neat and convenient installation in electrical panels

Applications

For engineers / R&D specialists:
An excellent choice for designing three-phase energy metering, protection, or monitoring systems where a 1 A RMS signal is required for relays, meters, or analyzers, while covering a very wide current range.

For electrical and measurement laboratories:
DIN rail format, clear terminals, and standard 24 V DC supply enable fast and safe installation in electrical panels. Suitable for both new installations and system upgrades.

For industrial engineering (high requirements):
Used in distribution panels, substations, factories, and data centers where reliable three-phase current measurement and compatibility with existing CT-type equipment are required.

Advantages

Three-phase solution in a single enclosure
1 A RMS output – widely used in industry
DIN rail mounting
Safer alternative to classic current transformers

Disadvantages

Fixed rated current
AC current measurement only
Requires an external DC power supply
Narrower frequency range compared to laboratory-grade integrators
