Socomec DIRIS A40 Class 0.5S Power Analyser

The Socomec DIRIS A40 Class 0.5S Power Analyser (model 48250041) is a high-precision multifunction power measurement instrument designed for revenue-grade submetering, energy allocation, and power quality monitoring in large industrial and commercial facilities across Saudi Arabia. With Class 0.5S accuracy for active energy measurement — compliant with IEC 62053-22 — the DIRIS A40 delivers the metrological performance required for tenant submetering in industrial zones, cost allocation between production departments, and energy performance benchmarking under the Saudi Energy Efficiency Program (SEEP) and Vision 2030 sustainability mandates. The Class 0.5S designation is the highest accuracy class defined in IEC 62053-22 for active energy, representing an accuracy of ±0.5% across a 20:1 current range — a performance specification that is explicitly required by both Saudi Aramco and SABIC for submetering applications within their industrial cities and facilities.

The DIRIS A40 measures all relevant power system parameters simultaneously: true RMS voltage and current on all phases, active power (kW), reactive power (kVAR), apparent power (kVA), power factor, displacement power factor, demand, THD on voltage and current up to the 31st harmonic, and energy (kWh, kVARh, kVAh) with dual tariff (T1/T2) and import/export capability. This comprehensive measurement coverage in a single DIN-rail device makes the DIRIS A40 the standard submetering instrument in ARAMCO's industrial submetering programs, where energy cost allocation between tenants in industrial parks and between process areas in large plants requires legally defensible metrological accuracy. Saudi Aramco's energy management standard references Class 0.5S accuracy for internal energy allocation meters, and the DIRIS A40 is the most widely used compliant instrument for these applications.

In the SABIC industrial cities context, the DIRIS A40 is deployed at feeder panel level to provide energy usage data for each production department, enabling SABIC's energy managers to identify inefficiencies, benchmark equipment performance, and report to corporate sustainability programmes. The instrument's Modbus RTU output connects directly to SABIC's plant information management systems (PIMS), and its optional Ethernet/Modbus TCP variant (DIRIS A40 with E2 option) integrates with web-based energy management software without a gateway. For NEOM smart district metering systems, the DIRIS A40's IEC 62053-22 Class 0.5S certification satisfies the smart city metering accuracy requirements in the NEOM utility infrastructure specifications.
