Why Choose the Lovato DMK11R1 Three-Phase Digital Ammeter?
The Lovato DMK11R1 is a compact and dependable three-phase digital ammeter designed for continuous AC current monitoring, control and protection in industrial switchboards, motor control centres and machinery panels. It measures and displays the current flowing through each phase, providing operators with a clear overview of electrical loading across a three-phase system.
The instrument uses True RMS measurement to deliver reliable current readings, including in installations where waveform distortion is produced by variable speed drives, electronic power supplies and other non-linear loads. It is designed for connection to external current transformers with a 5 A secondary output, allowing the displayed primary current to be scaled according to the installed CT ratio.
The DMK11R1 records the minimum and maximum current measured on each phase and includes a programmable changeover relay output for control, alarm and protection functions. Its compact 96 × 48 mm flush-mounted housing, removable terminals and IP54 front protection make it well suited to professional electrical panel installations.

Reliable Three-Phase Current Monitoring and Protection
Monitoring current across all three phases helps engineers identify overloads, phase imbalance, underloading and abnormal equipment behaviour. By displaying each phase independently, the Lovato DMK11R1 enables operators to compare electrical loading and detect conditions that could reduce efficiency or damage connected machinery.
The programmable relay output extends the instrument beyond basic indication. It can activate an external alarm, switch a contactor or interface with a control system when a configured current condition occurs, making the DMK11R1 suitable for overload supervision, undercurrent detection and automated process protection.
Typical Applications
