Product information

for panel mounting

DIRIS A-40 is a panel-mounted power monitoring device (PMD). It is designed to measure, monitor and report electrical energy.

DIRIS A-40 offers a range of functions for measuring voltage, current, power, energy and quality. It enables the analysis of a single-phase or three-phase load.

Benefits

Supported configuration

The configuration wizard guides the user step by step. It also detects and corrects configuration errors. This halves the time required for commissioning and ensures a reliable result every time.

Intelligent sensors
With three current sensor formats (non-split TE, split TR and Rogowski coil TF), DIRIS A-40 can be integrated into new and existing installations.

Cloud connection
The range includes IoT-ready connected products that enable automatic data export for remote operation without time, space or time restrictions.

Compliance with IEC 61557-12
The IEC 61557-12 standard is the reference for PMDs (Performance Metering + Monitoring Devices). Compliance guarantees the performance of the PMDs under the environmental conditions typical for industrial and tertiary applications.
