Narrative

Technical Innovation & Quality Heritage

YTL’s Multi-circuit Monitoring Meters are the ultimate solution for high-density power distribution panels. As a specialized manufacturer, Zhejiang Yongtailong has developed these meters to monitor multiple independent single-phase or three-phase circuits from a single device. This significantly reduces installation time, hardware costs, and the physical space required in electrical cabinets. These smart meters are typically used in data centers, commercial malls, and industrial sub-distribution boards where monitoring dozens of individual loads is necessary. Featuring shared voltage sensing and individual current transformer (CT) inputs for each circuit, they provide a streamlined, professional way to achieve granular energy visibility across an entire facility using a single communication gateway.

Product Application

  • Data Center Rack PDU Monitoring
  • Commercial Mall Tenant Sub-billing
  • Smart Manufacturing Power Analysis

Data Center Rack PDU Monitoring

In modern data centers, monitoring the energy consumption of every server rack is vital for capacity planning and "hot spot" detection. Instead of installing 50 separate meters, a few YTL multi-circuit meters can monitor all the individual power feeds in a distribution row. The compact design and high-speed Modbus communication provide the facility manager with a real-time heat map of energy usage, ensuring that no single rack is overloaded and allowing for precise energy cost-to-customer allocation in colocation environments.

Commercial Mall Tenant Sub-billing

Perfect for shopping centers where dozens of small shops or kiosks are fed from a centralized electrical room. The multi-circuit meter allows the mall management to monitor up to 12 individual tenants using one single device. This saves massive amounts of space in the distribution cabinet and drastically reduces the wiring complexity. Each tenant’s usage is tracked independently with billing-grade accuracy, allowing for fair and automated monthly billing via the mall's centralized energy management software.

Smart Manufacturing Power Analysis

Industrial facility managers use multi-circuit meters to track the energy efficiency of multiple production lines simultaneously. By monitoring the power consumption of different motors, pumps, and conveyor systems from a single point, engineers can perform comparative analysis to identify which machines are underperforming or nearing failure. This granular, circuit-level data is essential for implementing ISO 50001 energy management systems and achieving long-term industrial energy efficiency goals without a massive investment in individual metering hardware.

Product Advantages

High-Density Space Saving

Consolidates the monitoring of multiple loads into a single compact unit, reducing the physical footprint in the electrical panel by up to 80% compared to traditional meters.

Cost-Effective Scalability

Lower per-circuit hardware and installation costs by sharing a single processor, display, and communication module across multiple independent metering points.

Simplified Data Integration

Aggregates data from multiple circuits into a single communication map (Modbus), making it much easier for BMS or SCADA systems to poll and process energy information.

Frequently Asked Questions

  • Q: Can I mix 1-phase and 3-phase circuits?

    A: Yes, our flexible multi-circuit meters can be configured to monitor a mix of single-phase and three-phase loads depending on your specific wiring needs.

  • Q: Do I need to shut down power to install them?

    A: If you use our "split-core" CTs, you can clip the sensors around the existing wires without disconnecting them, allowing for a "hot" installation with zero downtime.

  • Q: What is the maximum current per circuit?

    A: Since these use external CTs, the current limit is determined by the CTs you choose (e.g., 50A, 100A, or even 600A for larger industrial loads).

  • Q: How do I identify which circuit is which?

    A: Each circuit has a unique register address in the Modbus map and can be given a custom label (e.g., "Shop 101", "AC Unit 4") in the management software.

  • Q: Does it have a local display?

    A: Yes, the meter includes an LCD and selection buttons that allow a technician to manually scroll through and view the readings for every connected circuit on-site.
