DAE P254-200-S KIT, UL CTEP kWh Smart Submeter
The DAE P254-200-S KIT is a UL/cUL listed, California CTEP approved 3-phase submeter rated for up to 200A and a wide voltage span from 120 to 480V. It uses three current transformers and supports RS485 communication, with optional cloud metering via the DAE CC2030 Gateway. This model adheres to ANSI C12.1 and C12.20 accuracy standards for revenue-grade performance (0.5%). It is suitable for both 3-phase 4-wire (with neutral) and 3-phase 3-wire (without neutral) configurations. Additional benefits include the ability to generate TOU billing reports and remote access to real-time data and monthly energy reports without requiring heavy IT support. The kit can be integrated with a cloud platform to provide tenant-specific billing and usage insights.
Eyedro 3-Phase Commercial & Industrial Energy Meter
Eyedro’s 3-Phase Commercial & Industrial meter provides real-time kWh, watts, amps, volts, power factor, and cost data. It supports both WiFi (2.4 GHz) and wired Ethernet connections, which allows flexible deployment in facilities with network constraints. The device handles a range of voltages up to 600V and uses a 3×200A sensor array (standard model), offering immediate insight into energy usage and potential solar generation versus consumption. Eyedro emphasizes robust technical support, making it a practical choice for facilities teams needing guidance during setup and ongoing monitoring. Real-time graphs and data history help with demand management and rate structure analysis.
Eyedro 3-Phase Commercial & Industrial Meter With 1000A Sensor
This Eyedro model upgrades sensor capacity to 3×1000A, enabling monitoring of higher-current loads common in larger commercial installations or facilities with significant electrical demand. It preserves Eyedro’s core strengths: real-time kWh, watts, amps, volts, and power factor, with optional cloud-enabled data retention. The high-sensor rating supports more comprehensive load analysis and can improve accuracy in systems where large motors or heavy machinery contribute to peak demand. As with the standard Eyedro meter, setup assistance and long-term data visualization tools help translate raw measurements into actionable energy management insights.
Acouto WiFi Circuit Breaker 3-Phase Rgy Meter
The Acouto 3-phase WiFi circuit breaker meter combines metering with protective features. It provides three-phase voltage, current, power factor, frequency, and other essential parameters via a compact unit. Its built-in guard features help detect voltage imbalances, overload conditions, and phase loss, enabling rapid responses to electrical faults. Ideal for residential multi-wire or small commercial setups, this meter aims to simplify monitoring while offering a practical, all-in-one solution. Network connectivity via WiFi makes it easy to access data remotely, supporting energy audits, occupancy-driven demand response, and maintenance planning without specialized IT infrastructure.
Buying Guide: Key Considerations For 3-Phase Sub Meters
- Voltage and current ratings: Ensure the meter supports your system voltage (commonly 120/208/240V, 277V, or higher 480V variants) and the maximum current per phase. For commercial buildings or industrial loads, a 200A or higher rating is often important.
- Phase configuration: Confirm whether the meter supports 3-phase 4-wire (with neutral) or 3-phase 3-wire (no neutral), and whether it’s compatible with your panel layout and CT/VT placement.
- Accuracy and billing capability: Revenue-grade accuracy (0.5%) is desirable for billing tenants or clients, while 1% or better suffices for general energy monitoring. Check compliance with ANSI C12.1 and C12.20 standards if you need formal billing validation.
- Communication options: Decide between RS485, Ethernet, WiFi, or cloud-enabled gateways. Cloud metering can simplify data access for property managers, while Ethernet offers stable, wired connectivity for critical monitoring.
- Installation and enclosure: Outdoor-rated enclosures and weather resistance reduce installation risk in exterior panels. Consider whether you need indoor or outdoor units and any required accessories (lower covers, knockouts, or mounting hardware).
- Data access and analytics: Some meters provide live dashboards, historical usage, and TOU (Time of Use) reports. Check whether they offer export formats or API access for integration with building management systems.
- Upgrade path and scalability: If your building plans to expand or reconfigure loads, choose meters that accommodate additional CTs or higher current ratings without a full replacement.
- Support and documentation: Reliable technical support and clear wiring diagrams simplify installation and ongoing troubleshooting, especially in multi-tenant environments.
When selecting a 3-phase submeter, balance accuracy, connectivity, and ease of installation with your specific building or industrial setting. Consider a meter that can grow with your needs, particularly if you anticipate more tenants, turbines, motors, or solar integration. Cloud-ready options are attractive for landlords and facility managers seeking remote access and scalable data analytics, while standalone meters with local readouts can be preferable in locations with limited network reach. Each option here emphasizes robust construction, clear data access, and configuration flexibility to support effective energy management across variedAmerican commercial and industrial applications.
