Why Choose the Lovato DM1TP0080 Current Transformer?

The Lovato DM1TP0080 is a precision solid-core current transformer designed for electrical metering, energy monitoring and power analysis applications. It provides an 80/5 A transformation ratio, converting primary current up to 80 A into a standard 5 A secondary signal for compatible meters, analysers and monitoring equipment.

The transformer features a generous Ø28 mm cable aperture and can also accommodate busbars measuring 30 × 10 mm, 25 × 15 mm or 20 × 20 mm. This makes the DM1TP0080 suitable for a wide range of switchboard and distribution-panel installations.

With a rated output of 2.5 VA at both Class 0.5 and Class 0.5s accuracy, the DM1TP0080 is well suited to applications requiring reliable current and energy measurement. Screw terminals, DIN rail or screw mounting and an IP30 enclosure support straightforward integration into professional electrical systems.

Key Advantages

  • Accurate 80/5 A current transformation for metering and monitoring applications.
  • Class 0.5 and Class 0.5s accuracy with a 2.5 VA rated output.
  • Large Ø28 mm aperture accepts substantial cable sizes.
  • Suitable for 30 × 10 mm, 25 × 15 mm and 20 × 20 mm busbars.
  • Supports both 35 mm DIN rail and screw mounting.
  • 120% continuous overcurrent capability supports dependable operation under demanding load conditions.

Key Features

  • Lovato DM1TP precision solid-core current transformer.
  • 80 A primary current.
  • 5 A secondary current.
  • 50–60 Hz operating frequency.
  • 2.5 VA output at Class 0.5s.
  • 2.5 VA output at Class 0.5.
  • 720 V rated insulation voltage.
  • Ø28 mm cable aperture.
  • Compatible with several rectangular busbar sizes.
  • Screw terminal connections.
  • IP30 protection rating.
  • Suitable for DIN rail or screw fixing.

Accurate Current Measurement for Energy Monitoring Systems

Current transformers such as the Lovato DM1TP0080 allow high primary currents to be safely converted into a standardised secondary current for measurement equipment. With an 80/5 A ratio, the transformer enables compatible energy meters, multifunction analysers and monitoring systems to measure circuit current without carrying the full primary load through the measuring instrument.

Its Class 0.5 and Class 0.5s accuracy and 2.5 VA rated output make the DM1TP0080 suitable for precise energy and current monitoring. The solid-core design is particularly appropriate for new installations where the primary cable or busbar can be passed through the transformer during panel assembly.

Typical Applications

  • Electrical energy metering systems.
  • Multifunction power analysers.
  • Industrial switchboards and distribution boards.
  • Commercial building energy monitoring.
  • Machine and production-line current measurement.
  • Power management and load-monitoring systems.
