DIRIS A40 multifunction meter

DIRIS A40 is a Panel Mounted Monitoring Device (PMD). It offers a range of functions for measuring voltage, current, power, energy and quality. It is designed for measuring, monitoring and reporting historical data and allows analysis of a single phase or three phase load.

Multi-measurement:

• Current - Instantaneous and maximum average I1, I2, I3, In
• Voltage and frequency - Instantaneous V1, V2, V3, U12, U23, U31, Usystem
• Frequency - 45-65 Hz
• Power - Instantaneous and maximum average 3P, ΣP, 3Q, ΣQ, 3S, ΣS
• Power factor - Instantaneous 3PF, ΣPF
• Energy - Active energy: +/- kWh Reactive energy: +/- kvarh - hours
• Harmonic analysis - THD Current, voltage, phase-to-phase voltage
• Events - Alarms on all electrical values
• Inputs - 3 digital inputs (pulse metering, status checking)
• Outputs - 2 outputs (alarms or pulses)

Power and energy measurement:

• Accuracy - 0.2 DIRIS A-40 Class only
• Active energy and active power - Class 0.5 with TE, TF or iTR sensors - Class 1 with TR sensors
• Accuracy of reactive energy - Class 2 with TE, TR or TF sensors
