Reliable & Accurate Current Measurement
Current transformers allow high AC currents to be measured using standard metering equipment by producing a proportional secondary current. The Lovato DM1TP0150 converts a primary current of 150 A into a standard 5 A secondary signal for compatible energy meters, multimeters and power analyzers.
Its Class 0.5S measurement capability makes the DM1TP0150 particularly suitable where accurate energy and current monitoring is required. The 28 mm aperture and compatibility with several common busbar dimensions provide installation flexibility across industrial switchboards, distribution panels and energy-management systems.
Typical Applications
- Industrial electrical distribution panels.
- Energy meters and power analyzers.
- Digital panel meters and multimeters.
- Industrial switchboards.
- Busbar current measurement.
- Building energy-management systems.
- Electrical load and consumption monitoring.
