Why Choose the Lovato DM5TP1250 Accuracy Current Transformer?

The Lovato DM5TP1250 is a precision solid-core current transformer designed for accurate electrical current measurement in industrial switchboards, energy metering systems and power monitoring installations. With a rated primary current of 1250 A and a standard 5 A secondary output, it converts high line currents into a safe and proportional signal for compatible meters, network analysers and measuring instruments.

Part of the Lovato Electric DM range, the DM5TP1250 is engineered for applications where dependable metering accuracy is required. It supports both accuracy class 0.5S and accuracy class 0.5, making it suitable for detailed energy measurement, load analysis and electrical monitoring across commercial and industrial systems.

The transformer accommodates cables up to 85.5 mm in diameter and is suitable for 100 × 20 mm or 80 × 45 mm busbars. Its solid-core construction provides a stable magnetic circuit, while the 1250/5 A transformation ratio enables straightforward integration with compatible 5 A measuring devices.

Key Advantages

  • Accurate 1250/5 A current transformation ratio.
  • Accuracy class 0.5S performance for precision energy metering.
  • Solid-core construction provides stable and dependable measurement.
  • Large 85.5 mm cable aperture for substantial conductors.
  • Compatible with 100 × 20 mm and 80 × 45 mm busbars.
  • Suitable for digital energy meters, network analysers and monitoring instruments.

Key Features

  • Lovato Electric DM series accuracy current transformer.
  • 1250 A rated primary current.
  • 5 A rated secondary current.
  • 50/60 Hz operating frequency.
  • 7.5 VA burden at accuracy class 0.5S.
  • 10 VA burden at accuracy class 0.5.
  • 120% primary-current overload withstand.
  • 720 V AC rated insulation voltage.
  • Suitable for cables up to 85.5 mm diameter.
  • Conforms to applicable IEC, EN and BS 61869 standards.

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.
