Multi-GEM 18: Branch Circuit Power Meter

The Multi-GEM 18 branch-circuit power meter delivers revenue-grade visibility across switchboards by measuring voltage, current, kW, kVar, kVA, power factor, frequency, unbalance and individual harmonics through the 31st on up to eighteen single-phase or six three-phase circuits. External split-core CTs—rated 100 mA or 333 mV and up to 6 000 A—clip around live conductors, while universal 50–690 V AC inputs and 50/60 Hz auto-sensing let one part number fit global installations. The device meets IEC 62053-22/-21 Class 0.5 S/1.0 for energy, logs demand plus sag-swell events, and flags total harmonic distortion to support EN 50160 compliance.

A compact DIN-rail form factor, tool-less screw terminals and printed wiring guides cut retrofit time, and LED indicators instantly confirm power, communication and CT polarity. Standard isolated RS-485 (Modbus-RTU) streams real-time data to PLCs or BMS platforms; an optional Ethernet module adds Modbus-TCP for cloud dashboards. One NTC input captures enclosure temperature, while a digital input and relay output enable breaker status or alarm signalling without extra I/O cards. Operating from −10 °C to +55 °C at up to 2 000 m altitude and 80 % humidity, the Multi-GEM 18 suits data centres, factories, malls and hospitals seeking ISO 50001 energy transparency and rapid ROI on efficiency upgrades.

Ordering codes specify CT output (10 mA, 100 mA or 333 mV) and wiring style (1P2W, 3P3W, 3P4W), ensuring the right configuration ships first time. Indoor-rated plastic housing carries CE marking, CAT III 600 V for measurement terminals and FCC Class B EMI compliance. With flexible channel mapping, modular communications and built-in power-quality analytics, Hqsensing’s Multi-GEM 18 translates raw branch-circuit data into actionable intelligence for smarter, more resilient electrical networks.
