Precision Measurement for Energy Monitoring Systems
Current transformers reduce high primary currents to a standard secondary current that can be safely measured by compatible electrical instruments. The Lovato DM5TP1250 converts a primary current of up to 1250 A into a proportional 5 A output, allowing connected equipment to measure current and energy consumption without carrying the full line current.
Its class 0.5S capability makes the DM5TP1250 particularly suitable for applications that require improved accuracy across a wider operating range. This supports reliable energy analysis, billing-related monitoring, load profiling and efficiency assessments in industrial and commercial electrical systems.
Typical Applications
- Precision energy metering systems.
- Industrial switchboards and distribution panels.
- Power quality and network monitoring equipment.
- Digital multimeters and energy analysers.
- Load profiling and consumption monitoring.
- Commercial building energy-management systems.
- Manufacturing and process-control facilities.
- Electrical infrastructure and utility monitoring.
