Why Choose the Lovato DM2TA1000 Split-Core Current Transformer?
The Lovato DM2TA1000 is a robust and reliable split-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 1000/5 A transformation ratio, it converts a primary current of up to 1000 A into a standard 5 A secondary output for connection to compatible energy meters, ammeters, multifunction measuring instruments and power analysers.
Its split-core construction allows the transformer to be opened and installed around an existing cable or busbar without removing the primary conductor. This makes the DM2TA1000 particularly suitable for retrofit metering projects, energy-management upgrades and existing electrical installations where reducing modification work and system downtime is important.
With a large 80 × 80 mm internal opening, the DM2TA1000 accommodates substantial cables and rectangular busbars commonly used in high-current power-distribution equipment. It operates at 50/60 Hz and provides a rated burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1, supporting dependable electrical measurement in demanding commercial and industrial environments.

Reliable Current Measurement for High-Load Electrical Systems
Current transformers provide a safe and practical method of measuring high electrical currents by converting the primary current into a proportional secondary signal for compatible instrumentation. The Lovato DM2TA1000 converts a primary current of up to 1000 A into a standard 5 A secondary output, enabling meters and monitoring devices to measure electrical loads without being connected directly to the high-current circuit.
The split-core construction is particularly valuable when adding metering equipment to an existing installation. Once the circuit has been safely isolated, the transformer can be opened, positioned around the cable or busbar and securely closed without removing or rerouting the primary conductor. This helps reduce installation labour and disruption while supporting effective energy management and electrical system analysis.
Typical Applications
- Industrial switchboards and high-current distribution panels.
- Energy meters and multifunction measuring instruments.
- Power analysers and electrical monitoring systems.
- Building and facility energy-management systems.
- Electrical load and maximum-demand monitoring.
- Industrial machinery and automation panels.
- Commercial power-distribution installations.
- Retrofit metering and energy-efficiency projects.
