Our Flexible Coils provide a versatile solution when space is limited and requires a rope-style current transformer to physically wrap around an irregular-shaped conductor or wire.
They are used with high amperages and are rated for 1000A to 3000A.
An integrator is included with output voltage in the mV range.

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.
