Why Choose the Lovato DM5TP1000 Current Transformer?
The Lovato DM5TP1000 is a precision solid-core current transformer designed for electrical current measurement in industrial switchboards, power distribution systems and energy monitoring installations. With a 1000/5 A transformation ratio, it converts a 1000 A primary current into a standard 5 A secondary signal for compatible meters, power analysers and monitoring equipment.
As part of the Lovato DM5TP current transformer range, the DM5TP1000 features a large 85.5 mm diameter cable opening and is also suitable for 100 × 20 mm or 80 × 45 mm busbars. Its solid-core construction makes it particularly suitable for permanent installations where the conductor can be routed through the transformer during assembly.
The DM5TP1000 provides accuracy class 0.5S at 5 VA and accuracy class 0.5 at 10 VA. It operates at 50–60 Hz, has a rated insulation voltage of 720 V and features screw secondary terminals with DIN rail or screw fixing for flexible integration into industrial electrical assemblies.

Precision Current Measurement for Industrial Systems
Current transformers enable large primary currents to be measured by converting them into a lower proportional secondary current suitable for electrical instrumentation. The Lovato DM5TP1000 provides a standard 5 A secondary output, allowing compatible meters and power monitoring equipment to measure currents in industrial distribution systems without carrying the full primary current through the measuring instrument.
The DM5TP1000 combines a large conductor aperture with precision 0.5S measurement capability, making it particularly suitable for energy metering and monitoring applications. Its solid-core construction is ideal for new switchboard installations where the cable or busbar can be routed through the transformer during assembly.
Typical Applications
- Industrial electrical switchboards and distribution panels.
- Energy metering and monitoring systems.
- Power analysers and multifunction measuring instruments.
- Large cable current measurement.
- Busbar current monitoring systems.
- Industrial plants and power distribution installations.
