LS Electric PM Series Power Meter (PM1, PM2, PM3)

The LS Electric PM Series Power Meters (PM1, PM2, PM3) are multifunction digital power analysers designed for energy monitoring, power quality measurement, and electrical metering in industrial, commercial, and infrastructure applications across Saudi Arabia. The PM3 — the flagship model — is a DIN96 x 96 mm panel-mount instrument measuring true RMS voltage (line-to-line and line-to-neutral), current (three-phase and neutral), active power (kW), reactive power (kVAr), apparent power (kVA), power factor, frequency, kWh import/export energy, maximum demand, and harmonic components up to the 31st harmonic for THD analysis. These measurement capabilities address the full scope of electrical energy monitoring requirements in Saudi Arabia, from basic kWh billing verification against SEC tariff invoices through to full power quality analysis for harmonic mitigation system design in industrial facilities.

The PM3 provides RS-485 Modbus RTU communication as standard, with an optional Ethernet (Modbus TCP / IEC 61850 GOOSE) module for integration into energy management systems, SCADA platforms, and building management systems. The Modbus register map is compatible with the most common energy management software platforms used in Saudi Arabia, including Schneider EcoStruxure Power, Siemens SICAM, and custom SCADA systems developed by Saudi system integrators. The PM3's internal memory stores up to 12 months of energy data at 15-minute intervals, providing local data logging without a SCADA connection — important for SEC industrial tariff maximum demand tracking and energy efficiency reporting under the Saudi Energy Efficiency Program (SEEP) requirements.

In Saudi Arabia, power metering is increasingly mandated by SEC regulations for large industrial consumers (LPC and HPC tariff categories) and is required at sub-metering level in multi-tenant industrial estates, commercial developments, and LEED/Estidama-certified buildings. The LS Electric PM3 is specified by Saudi MEP consultants, energy management engineers, and SEC-licensed electrical contractors as a cost-effective multifunction power meter that meets SEC metering accuracy requirements (Class 0.5S for billing, Class 1 for monitoring) at a competitive SAR price. Its IEC 62053 metering accuracy certification and compatibility with all major SCADA and energy management platforms make the PM3 suitable for both check metering and active energy management applications.

Razz Middle East supplies the full PM series from Saudi Arabia stock, including current transformers, Modbus communication cables, and power management software configuration support. Our energy team provides Modbus register mapping assistance and integration support for connection to customer SCADA and BMS platforms.
