Multi-GEM 12: Branch Circuit Power Meter

The Multi-GEM 12 is a compact branch-circuit power meter that squeezes advanced analytics into a 62 × 96 × 56 mm enclosure, making it ideal for crowded panels. One unit measures voltage, current, power, energy, power factor, frequency, unbalance, total harmonic distortion and sag-swell events on up to twelve single-phase feeders or four 3-phase 4-wire circuits. Accuracy meets IEC 61557-12 Class 1.0 for general monitoring or Class 0.5 for billing-grade audits, and external 100 mA or 333 mV split-core CTs clip on without powering down the load.

Universal 100–240 V AC/DC supply and 45–65 Hz autosensing let you standardise one SKU worldwide, while 50–690 V measurement windows cover everything from data-centre PDUs to factory MCCs. Native Ethernet Modbus-TCP provides real-time streaming to BMS, SCADA or cloud dashboards, and an optional Wi-Fi module supports rapid retrofits where cabling is costly. An RJ45 upgrade port, a removable dust-proof top cover and screw-free DIN-rail or wall mounting further cut installation time.

Designed for indoor use at altitudes up to 2 000 m, the meter operates from –10 °C to +55 °C and stores data safely down to –25 °C. With ISO 9001 manufacturing, IEC 62053-21/22 compliance and RoHS-3 materials, the Multi-GEM 12 brings enterprise-level visibility, accuracy and durability to sub-metering projects in offices, malls, hospitals and industrial plants.
