Accurate Current Measurement for Metering and Energy Monitoring
Current transformers such as the Lovato DM25T600 reduce a high primary current to a proportional 5 A secondary signal that can be safely measured by compatible instrumentation. This allows meters and power analysers to monitor high-current circuits without carrying the full load current directly through the measuring device.
The DM25T600 combines a compact solid-core design with multiple cable and busbar mounting options, making it well suited to switchboards, distribution panels and energy-monitoring systems. Its defined accuracy classes and 600/5 A ratio support dependable measurement in a wide range of commercial and industrial installations.
Typical Applications
- Energy meters and multifunction power analysers.
- Industrial switchboards and distribution panels.
- Electrical load monitoring systems.
- Power and energy management installations.
- Commercial building electrical distribution.
- OEM machinery and control panels.
