The split core current transformers produce a scaled down AC current in the secondary windings that is directly proportional to the AC current in the primary conductor around which they are placed.
These transformers are safely and easily installed over existing electrical power lines without disconnecting lines or otherwise interrupting service.
The output to the Power Meter is in the mA range, and they have internal over-voltage protection to limit the maximum unburdened voltage output to a safe level.
They are designed to fit into confined spaces while the primary conductor is still live.
They are a compact design with a mechanical hinge for multiple opening and closing actions.

Our software doesn’t require a dedicated installation with additional hardware for hosting, and there are no hidden costs or maintenance costs.
The EG-200 is an open Linux gateway, with RS485 Modbus RTU, Modbus TCP and MQTT, HTTP & SNMP interfaces.
Power Meter EM
Use the Power Meter to measure branches up to 3000A, using a standard Modbus-RTU to provide voltage, current, power factor and frequency data for 1-3 phases, as well as temperature.
Power Bar EB
The EB is a compact AC current and power measurement device that enables accurate monitoring of every breaker of interest, without taking up any DIN-rail space.
Split Core CT
For use with EM power meters. Our Split Core CTs are available in three window sizes and rated from 80A to 500A.
The flexible coil current transformers are based on the Rogowski principle and have been designed for accurate, non-invasive measurement of AC current.
The premade Modbus cables by eTactica are designed to make it easier to set up Modbus devices that use Molex connectors.
