DAE P254-200-S KIT – 3 Phase 200A Submeter
The P254-200-S KIT is a UL/cUL listed submeter designed for 3-phase systems from 120 to 480V. It uses three current transformers (CTs) to measure phase currents and provides RS485 communication for data collection. The meter conforms to ANSI C12.1 and C12.20 accuracy standards with a revenue-grade 0.5% accuracy, making it suitable for tenants’ billing and energy auditing. It includes a lower cover with two 3/4″ conduit knockouts for straightforward installation. It supports both 3-phase 4-wire and 3-phase 3-wire configurations and can be connected to DAE CC2030 Gateway for cloud metering. TOU billing reports are available, and remote monitoring is possible without a dedicated IT resource.
DAE P256-200-S KIT – 200A 277/480V Submeter
The P256-200-S KIT provides 3-phase, 4-wire or 3-wire measurement with a 200A rating and 277/480V compatibility. It comes with a lower cover featuring two 3/4″ knockouts for conduit connections and is UL/cUL listed with ANSI C12.1 compliance. Like other DAE meters, it supports cloud metering via the CC2030 gateway, enabling real-time monitoring, monthly kWh, and TOU reports. This model targets installations needing a higher voltage tolerance and reliable data logging through RS485 interfaces. Ideal for multi-tenant buildings or commercial applications requiring robust metering data.
DAE P254-400 KIT – 400A Submeter
The P254-400 KIT is a higher-current option for three-phase systems at 120-480V. It features three split CTs with an inner diameter suitable for larger CTs, and a lower cover for easy conduit entry. UL/cUL listed and ANSI C12.1 compliant ensures accuracy and reliability, with a 0.5% revenue-grade accuracy. It can connect to DAE CC2030 Gateway for cloud-based energy management, including real-time data, monthly kWh, and TOU metrics. This model is well-suited for commercial facilities with higher load demands or retrofits where precise metering is critical for billing accuracy.
DAE P204-200D-S KIT – Demand Submeter
The P204-200D-S KIT is a demand-capable submeter designed for 3-phase, 120-480V service with 200A capacity and three CTs. It carries UL/cUL listing and ANSI C12.1/C12.20 compliance for revenue-grade accuracy (0.5%). The kit includes a lower cover with two 3/4″ knockouts for easy wiring, and it works with the DAE CC2030 Gateway for cloud-based energy analytics. Like other DAE meters, it supports TOU reporting and data access via devices without needing an IT professional. It is appropriate for facilities seeking demand metering alongside energy usage.
HZVEKCRI 100A-1000A 3-Phase Kit
The HZVEKCRI 100A-1000A 3-phase meter offers a broad current range with RS485 communication and a clamp sensor option. It is designed for 480V systems and emphasizes energy monitoring across three phases with clear readings. The clamp sensor supports non-invasive current measurement, making it suitable for retrofit installations where routing CTs through current transformers is challenging. This model provides flexibility for both hobbyist upgrades and commercial installations requiring scalable metering across varying load profiles. RS485 facilitates data collection into building management systems or analytics platforms.
Buying Guide: Key Considerations for 480V 3-Phase Meters
- Current rating and CT configuration: Choose a model matching the system’s maximum load (e.g., 200A, 400A). Split CTs or external CTs affect installation complexity.
- Voltage compatibility: Ensure the meter supports 120-480V or higher to cover 3P/4W and 3P/3W configurations as needed.
- Communication interface: RS485 is common for integration with data loggers and SCADA systems; verify Modbus RTU compatibility and wiring requirements.
- Compliance and accuracy: Look for ANSI C12.1/C12.20 compliance and revenue-grade accuracy (often 0.5%) for billing and regulatory reporting.
- Cloud metering options: If you want remote monitoring, confirm gateway compatibility (e.g., DAE CC2030) and TOU reporting capabilities.
- Installation environment: Indoor vs. outdoor suitability, enclosure ratings, and conduit knockouts affect where you can mount the meter.
- Future scalability: If loads will grow, consider a meter with higher current rating or modular CT configurations to minimize replacement later.
- Certification and support: UL/cUL listings support insurer and building code requirements; ensure vendor provides installation guidance and videos.
