Why Choose the Lovato DMK01R1 Single-Phase Digital Ammeter?
The Lovato DMK01R1 is a compact and reliable single-phase digital ammeter designed for accurate AC current monitoring, control and protection in industrial switchboards, machinery panels and electrical distribution systems. It displays the present current together with stored minimum and maximum values, helping operators monitor equipment loading and identify abnormal operating conditions.
The instrument uses True RMS measurement to provide dependable readings, including in circuits affected by waveform distortion from variable speed drives, electronic power supplies and other non-linear loads. It is designed for connection through an external current transformer with a 5 A secondary, allowing primary currents up to 10,000 A to be displayed when the correct CT ratio is programmed.
Unlike the standard DMK01, the DMK01R1 incorporates a programmable relay output for control and protection functions. The relay can operate alarms, contactors or control circuits when configured current thresholds are reached. Its compact 96 × 48 mm panel-mounted format makes it suitable for professional switchboard and control-panel installations.

Current Monitoring with Programmable Relay Control
Digital panel ammeters provide continuous indication of electrical current, helping engineers monitor equipment loading, identify overload conditions and assess changing demand within an installation. Recording minimum and maximum current values also makes it easier to investigate operating peaks that occur between routine inspections.
The programmable relay output allows the Lovato DMK01R1 to perform more than basic current indication. It can activate an external warning, switch a contactor or interface with a control system when the measured current crosses configured thresholds, making it suitable for overload supervision, undercurrent detection and general process protection.
Typical Applications
- Industrial switchboards and electrical distribution panels.
- Motor control centres and machinery panels.
- Motor overload and underload monitoring.
- Pump, fan and compressor systems.
- Generator and power supply monitoring.
- Alarm and protective control circuits.
- Manufacturing and process equipment.
- Current monitoring through external 5 A current transformers.
