DMK01 – DIGITAL AMMETER 1 PH 96X48MM
Lovato DMK01 single-phase True RMS digital ammeter with a 5 A current transformer input, minimum and maximum current memory and 96 x 48 mm flush-mounted housing.
Why Choose the Lovato DMK01 Single-Phase Digital Ammeter?
The Lovato DMK01 is a compact and reliable single-phase digital ammeter designed for accurate AC current monitoring in industrial switchboards, machinery panels and electrical distribution systems. It displays the present current value together with stored minimum and maximum readings, helping operators assess electrical loading and identify abnormal operating conditions.
The instrument uses True RMS measurement to provide dependable current readings, including in installations where waveform distortion may be caused by variable speed drives, electronic power supplies or other non-linear loads. It is designed for connection through an external 5 A current transformer, allowing the meter to monitor a wide range of primary currents according to the selected CT ratio.
With a compact 96 × 48 mm flush-mounted format, removable terminals and a clear digital display, the DMK01 integrates neatly into control panel doors and switchboard assemblies. Its IP54 front protection and robust thermoplastic housing support dependable service in industrial and commercial environments.

Reliable Current Monitoring for Electrical Panels
Digital panel ammeters provide continuous indication of electrical current, allowing operators and maintenance engineers to monitor equipment loading without relying on portable test instruments. Tracking current can help identify overloads, load imbalance, mechanical stress and developing faults in motors, heaters and other electrical equipment.
The Lovato DMK01 also records minimum and maximum current values, making it easier to review loading variations that occur between inspections. Its programmable current transformer ratio allows the displayed value to represent the actual primary current flowing through the monitored circuit.
Typical Applications
- Industrial switchboards and distribution panels.
- Motor control centres and machinery panels.
- Generator and power supply monitoring.
- Pump, fan and compressor systems.
- Heating and process equipment.
- Commercial building electrical installations.
- Manufacturing and production machinery.
- Current monitoring through external 5 A current transformers.
