Selection at a glance
- DIN-rail mount and a short body, so several outgoing feeders in a distribution board can be added or retrofitted quickly.
- External precision CTs, harmonic analysis, and LoRa (see the table) cover both billing-grade measurement and IoT reporting.
- A temperature-compensated clock and a tariff model are optional, for peak, shoulder, and off-peak rates and for demand response.
- SimtoLink can advise on remaining rail length, busbar spacing, and terminal torque.
Product overview and engineering role
Aimed at distribution cabinets, PDU rows, and submetering retrofits. Compliant metering and communications fit in a short DIN length, so a second cutout or an extra cabinet is less often required.
SimtoLink can supply a LoRa channel plan, a collector point-list template, and a batch time-sync script. The meter can ship in the same family as the three-phase multifunction meter and the multi-circuit meter.
Reliability and site fit
Salt-spray and vibration type tests cover the electrical-safety and EMC claims. Ports include surge and reverse-polarity protection. Reinforced earth and a split layout reduce ground loops and common-mode pickup. Outdoor and coastal cabinets can take a higher ingress rating and a corrosion-resistant finish.
Parameters can be imported in batches, with threshold rules and event or waveform capture where the order code includes them. Configuration and firmware can be updated over the air. On site, accept the meter in three steps: power-on self-test, time sync, and a sample check. Metering and safety jobs can include help with a third-party metrology submission and type-test papers.
Key hardware parameters
The rows are the typical DIN-rail build for a bid schedule. Ask if you need a wider span, a redundant supply, or an intrinsically safe variant, and SimtoLink will send the hardware specification and the installation guide. Order codes in the family are not identical; the nameplate and the pack list decide.

Typical applications
Three places this meter usually lands, useful when you are still choosing and when you are signing off the joint test:
Data-center PDU rows
Each IT or cooling feeder is metered on its own, and the dense rail mount leaves room to add circuits later.
Retail tenants in a mixed-use building
Shop and common-area energy is split, and LoRa aggregation cuts the cost of RS485 home-runs.
Energy-retrofit EPC
Submeters go into the existing MCC so savings can be checked against the baseline.
Installation, grounding, and maintenance
- Confirm supply range and polarity before the breaker is closed, and meter the bus if the drawing is unclear.
- Run communications on shielded twisted pair, bond the shield at one end only, and keep it off long parallel runs with power cable.
- Prove two-way register access and a threshold trip in the lab before the meter leaves for site.
- Outdoors, give water a way out and air a way through, inspect the seal faces, and hold the lightning earth to the local limit.
- While the meter stays in service, pull a sample check and archive logs every 12 months.
Ordering, documentation, and support
The pack includes the hardware specification, an outline drawing, a wiring table, and a sample project. A volume order can add a sample review and a resident factory inspection. Warranty and calibration stay with the contract and the documents that travel with the meter.
