Monnit ALTA Industrial Wireless Three Phase Current Meter - 150 Amp

The Monnit ALTA Industrial Wireless Three Phase Current Meter (150 Amp) is a rugged, high-accuracy solution designed to illuminate the health and efficiency of large electrical systems. By capturing RMS current across a three-phase power network using three clamp-on current transformers, this meter delivers real-time visibility into per-phase demand, peak loading, and overall energy patterns. Ideal for industrial facilities, data centers, manufacturing lines, and HVAC installations, the ALTA meter integrates seamlessly with Monnit’s wireless IoT ecosystem to empower proactive energy management, smarter maintenance decisions, and scalable monitoring across multiple points in your facility.

• The ALTA current meter measures RMS current for a complete three-phase system with precision, using 3 current transformers (CTs) that wrap around the individual conductors. This setup provides accurate per‑phase data and a comprehensive view of how each leg of your system performs—essential for balancing loads, preventing overloads, and optimizing conductor sizing. With 150 A per CT capability, you can monitor typical industrial currents with confidence and capture meaningful trending data over time.
• Wireless, cloud-connected monitoring transforms how you access data. The ALTA sensor communicates with Monnit gateways, transmitting readings to the cloud where you can view real-time values, historical trends, and alerts from any web-enabled device. This eliminates complex wiring to a centralized SCADA or historian, reduces installation costs, and enables rapid scaling as your monitoring footprint grows across machines, rooms, or facilities.
• Key measurements at a glance. The sensor reports Minimum RMS current, Maximum RMS current, and Average RMS current, giving you a complete snapshot of system behavior. This trio of metrics helps you identify outliers, detect transient spikes, and confirm that your three-phase loads remain within safe and economical ranges. By tracking min, max, and average values, you can tune protection settings, planner maintenance windows, and optimize energy usage with data-driven decisions.
• Designed for rugged industrial environments, the ALTA meter emphasizes reliability and ease of use. The three CTs clamp-around conductors without disconnecting equipment, reducing downtime and enabling non-invasive monitoring. The wireless link supports long-range communication and robust data delivery even in challenging factory floors, warehouses, or outdoor enclosures, helping you maintain continuous visibility without the headaches of extensive wiring or frequent manual readings.
• Integration and scalability for energy management programs. Beyond basic current sensing, the ALTA meter integrates into a broader energy management strategy. It supports alerting rules, usage analytics, and dashboards that align with sustainability or efficiency goals. Whether you’re reducing peak demand charges, validating equipment performance, or benchmarking energy use across lines and shifts, this instrument provides the reliable data backbone you need to drive meaningful improvements.

How to install Monnit ALTA Industrial Wireless Three Phase Current Meter

• Power down or isolate the relevant electrical circuit as required by your safety protocol, then identify the three phase conductors that will be monitored.
• Place each CT around its corresponding conductor so the wire passes through the CT’s opening, ensuring it is fully seated and oriented according to the included installation guide.
• Connect the CT leads to the ALTA meter’s input ports as specified in the user manual, confirming secure and correct polarity and connector seating to prevent data loss or misreads.
• Mount the ALTA device in a suitable location that is accessible for maintenance and safe from moisture, dust, and physical damage, while ensuring the device has clean air and is not exposed to direct heat sources.
• Provide power to the ALTA meter if required by your installation model and verify that the wireless radio is enabled for communication with your Monnit gateway or network.
• Pair the ALTA meter with your Monnit gateway or central monitoring system, assign sensor IDs, and configure any desired alert thresholds or data logging intervals through the Monnit portal for rapid visibility and early warning.
• Power up the system and verify that readings appear in the Monnit dashboard, then perform a brief load test to confirm accurate phase-by-phase current readings and consistent wireless data transmission.

Frequently asked questions

• Q: What exactly does the 150 Amp specification refer to? A: The 150 A rating applies to each current transformer used with the three-phase meter, defining the maximum current per phase that the CTs can accurately measure under typical operating conditions.
• Q: How does the ALTA communicate data? A: The ALTA uses wireless transmission to a Monnit gateway, with data then uploaded to the cloud for real-time dashboards, historical reports, and alerts accessible from anywhere you have network access.
• Q: Can I monitor multiple machines or locations with this device? A: Yes. The ALTA meter is designed for scalable wireless monitoring; you can deploy additional meters across lines, rooms, or facilities and aggregate data in a single Monnit portal for centralized visibility.
• Q: Does the meter require a dedicated power source? A: The device is designed to function within the Monnit wireless ecosystem and the specific power requirements are provided in the product manual; ensure you follow the recommended power and safety guidelines during installation.
• Q: Can I get alerts if current exceeds a threshold? A: Yes. You can configure alert rules within the Monnit portal to notify you when RMS current per phase surpasses predefined limits, enabling proactive maintenance and load management.
• Q: Does the ALTA measure voltage or power factor? A: The ALTA current meter focuses on RMS current measurements for three-phase systems and reports min, max, and average values; for voltage, power factor, and other electrical parameters, additional sensors or meters would be needed in your monitoring suite.
