SOCOMEC DIRIS A40 48250201 Product Description

Overview

SOCOMEC DIRIS A40 48250201 is a Socomec DIRIS A-40 power monitoring device, also called a multifunction electrical meter or PMD, supplied in a 96 x 96 mm door-mounting format. The reference 48250201 identifies a DIRIS A40 base meter configuration in the A40/A41 meter family. The device measures, monitors and manages electrical energy for single-phase or three-phase installations, combining voltage, current, power, energy, power factor, frequency, temperature and harmonic distortion measurements for electrical distribution, energy efficiency, power quality and remote monitoring applications. It is installed in switchboards, control panels, motor control centers, feeders and machine or process power circuits, and used as a replacement multifunction meter in existing Socomec DIRIS installations.

Features

SOCOMEC DIRIS A40 provides multi-measurement functions for current, voltage, frequency, power, power factor, temperature, energy and harmonics. Current measurements include instantaneous phase current, neutral and system current, plus average or maximum average current values. Voltage and frequency measurements cover instantaneous phase-to-neutral and phase-to-phase voltages, system voltage, frequency and average or maximum average voltage and frequency values. Power measurements include instantaneous three-phase and total active, reactive and apparent power, average or maximum average values, and predictive total power values.

The meter meters active energy in +/- kWh, reactive energy in +/- kvarh, and apparent energy in kVAh, together with operating hours. Harmonic analysis reports distortion rates for phase currents, neutral current, phase-to-neutral voltages and phase-to-phase voltages. The device supports load curve recording for active and reactive power, voltages and frequency on applicable versions. Temperature monitoring includes internal temperature and external measurement through up to three PT100 sensors, connected in 2, 3 or 4-wire format.

DIRIS A40 provides two configurable pulse outputs for active, reactive or apparent energy, with configurable pulse type, weight and run. Auxiliary power supply covers 110 to 400 VAC with ±10 percent AC tolerance, or 120 to 350 VDC and 12 to 48 VDC with listed DC tolerance, at 50 / 60 Hz and consumption up to 10 VA. Active energy accuracy follows IEC 62053-22 class 0.5 S, and reactive energy accuracy follows IEC 62053-23 class 2. Communication options vary by DIRIS A40 version and may include RS485 Modbus, Ethernet with RJ45 at 10BASE-T / 100BASE-T, Modbus TCP or JBUS/MODBUS RTU over TCP. The meter is compliant with IEC 61557-12 and EN 50160, and carries UL 61010 and CSA approval references.

Principle

SOCOMEC DIRIS A40 48250201 connects to a low-voltage electrical feeder through current sensors or current transformers and voltage measurement inputs. The meter samples phase voltages and currents, calculates active, reactive and apparent power, power factor, frequency, energy accumulation, harmonic distortion and temperature values, and displays them on its local backlit LCD. Configured pulse outputs can export energy pulses to external logging or billing systems, while communication ports can transfer measurements, energy data, alarms or load-curve information to supervision software, PLC, SCADA, building management system or cloud-based energy monitoring platforms.

Configuration is performed through the meter keypad, setup software or assisted configuration wizard, according to the wiring arrangement, sensor type, CT or PT ratio, energy pulse scaling and communication settings. The PMD is designed for measurement and monitoring under typical industrial and commercial electrical installation conditions. Replacement should verify the exact A40 version, communication port, input and output arrangement, sensor compatibility and supply voltage against the original Socomec meter label and documentation before installation.

Applications

SOCOMEC DIRIS A40 48250201 is used for power availability monitoring, energy metering, sub-billing, power quality analysis, load monitoring, industrial process power management, data center and telecom power supervision, building life-safety power monitoring, plant distribution, motor control centers, switchboards, feeders, production lines, pumps, fans, compressors, conveyors, HVAC, lighting distribution, water and wastewater, chemical and process plants, utilities and general commercial electrical panels. In existing DIRIS A40 installations, the unit serves as a direct replacement multifunction meter matched to the original panel mounting, sensor connections, wiring and communication configuration.
