MULTIFUNCTION MEASURING UNIT (DIRIS A14)

Multi-function energy meter available in two distinct physical formats to suit either distribution boards or panel doors.

• physical format: available in DIN-rail (modular, 4 modules width) or Door-mount (96*96 mm flush-mount) versions

• display: backlit LCD screen for direct reading of energies, currents, and voltages

• dimensions (W x H x D):

  • DIN-rail: 72 *90*64 mm

  • Door-mount: *96* 96*69.5 mm

• weight:

  • DIN-rail: ~240 g

  • Door-mount: ~450 g

• ingress protection: Case IP20 / Front Face IP51

• electrical inputs:

  • voltage: 50–460 VAC (Phase-to-Phase) / 290 VAC (Phase-to-Neutral); direct measurement (no VT needed)

  • current: requires external Current Transformers (CTs) with 5A secondary (Primary range 10...2500A)

  • power supply: self-powered via voltage inputs (auxiliary source not required)

• accuracy (metrology):

  • active energy: Class 0.5S (IEC 62053-22) / Class C (MID EN 50470) – high precision

  • reactive energy: Class 2

• connectivity:

  • wiring: compatible with Single-phase (1P+N), Two-phase, or Three-phase (3P, 3P+N) networks

  • terminals: rigid cable 1.5–10 mm² / flexible 1–6 mm²

  • communication: integrated RS485 (Modbus RTU) for remote monitoring

An MID-certified multi-measurement meter (PMD) designed for low voltage networks. It performs bi-directional metering (measuring both energy consumption and production) and monitors real-time electrical parameters (Current, Voltage, Power, Power Factor).

• specific applications:

  • Legal Sub-Billing: The MID "Module B+D" certification provides the guaranteed accuracy required for sub-billing applications. This is essential for compounds where electricity costs must be legally re-invoiced to external partners or rented facilities.

  • Grid vs. Solar Monitoring: The 4-quadrant bi-directional metering distinguishes between imported energy (from Grid/Generator) and exported energy (from Solar PV), allowing for detailed analysis of hybrid power systems.

  • Installation Troubleshooting: The device includes a connection error detection function that warns of common wiring mistakes (like phase/neutral inversion), securing the installation in complex field distribution boards.

  • Power Quality Analysis: It measures Total Harmonic Distortion (THD) on currents and voltages, helping logisticians identify "dirty power" sources (non-linear loads) that could affect sensitive medical equipment.
