What's the difference between single-circuit and multi-circuit measurement units?

Single-circuit vs multi-circuit measurement units:

• Single-circuit units : Monitor one electrical circuit (one phase L1, or three phases combined). Ideal for residential, small commercial, or simple industrial installations. Compact, cost-effective.
• Multi-circuit units : Simultaneously measure multiple independent circuits (typically 6-12 circuits). Perfect for buildings with separate zones, multi-tenant properties, or large industrial installations.
• Measurement parameters : Both measure voltage, current, power (kW), power factor, frequency, energy (kWh), harmonics up to 63rd harmonic.
• Communication : Both support Modbus RTU/RS485, Modbus TCP, Profibus, BACnet, M-Bus, and pulse output for integration with SCADA/BMS systems.
• Socomec solutions : DIRIS, POWERSYS meter families offer single and multi-circuit options certified to IEC 62053-22 (Class 0.5S/0.2S).

Optim-Elec, specialist Socomec distributor at Gennevilliers (92), recommends multi-circuit for energy management, cost allocation, and demand response applications. Single-circuit units suit facilities with homogeneous load profiles. Contact optim-elec.com for installation assessment.
