Narrative

Technical Innovation & Quality Heritage

YTL’s DIN Rail Smart Meters are the professional choice for space-constrained electrical panels. Unlike traditional large-form factor meters, these units are designed to snap directly onto a standard 35mm DIN rail. As an expert manufacturer, Zhejiang Yongtailong has condensed high-performance smart metering technology into a modular width (from 1-module to 7-module). These meters are ideal for sub-metering in commercial malls, industrial equipment monitoring, and modern "smart" distribution boards. Despite their small size, they offer full bi-directional measurement, RS485 or wireless communication, and Class 1.0 accuracy. They provide a clean, organized, and scalable solution for monitoring multiple circuits within a single cabinet, making them the industry standard for modern building automation and energy management.

Product Application

  • Commercial Sub-billing
  • Industrial Machine Monitoring
  • Smart Home Distribution Boards

Commercial Sub-billing

The perfect solution for shopping centers and office complexes where energy costs need to be allocated to individual tenants. The compact DIN-rail design allows dozens of smart meters to be installed in a single centralized distribution panel. Combined with RS485 communication, the building management system can automatically collect readings for all tenants simultaneously, ensuring fair and accurate billing while saving massive amounts of physical space.

Industrial Machine Monitoring

Used by factory managers to track the energy efficiency of specific high-power machines like air compressors, CNC centers, or injection molders. By mounting the meter directly on the DIN rail inside the machine's control cabinet, engineers can identify power quality issues and monitor real-time consumption, helping to implement predictive maintenance and reduce the carbon footprint of the manufacturing process.

Smart Home Distribution Boards

Designed for integration into modern home automation systems. These meters fit perfectly alongside standard circuit breakers, allowing homeowners to monitor their total household load or specific branches like EV chargers and HVAC systems. The clean, modular installation ensures that the smart technology doesn't clutter the home's electrical panel while providing high-speed data for energy-saving apps.

Product Advantages

Compact Modular Design

Fits standard 35mm DIN rails, allowing for a much higher density of meters in a single cabinet compared to traditional wall-mount designs, reducing panel costs.

Rapid Installation

Snaps on in seconds with no mounting screws required, significantly reducing labor time for large-scale sub-metering projects and industrial retrofits.

High-Precision Metrology

Despite the small footprint, these meters use the same high-grade measurement chips as our utility meters, ensuring Class 1.0 accuracy for reliable billing and auditing.

Frequently Asked Questions

  • Q: How many modules wide is the 3-phase meter?

    A: Our standard 3-phase DIN rail smart meters are typically 4 modules (72mm) or 7 modules (126mm) wide, depending on whether they are direct-connect or CT-operated.

  • Q: Can I use it to measure both directions (Solar)?

    A: Yes, many of our DIN rail models support bi-directional measurement, making them ideal for monitoring solar generation and grid export in small-scale PV systems.

  • Q: Does it have a pulse output?

    A: Yes, all our DIN rail meters feature a standard S0 pulse output for easy integration into legacy energy management systems or data loggers.

  • Q: What is the maximum current for the 18mm model?

    A: Our ultra-compact 1-module (18mm) meters can typically handle up to 45A or 50A direct connection, making them perfect for single-phase branch circuits.

  • Q: Can I read the data via Modbus?

    A: Absolutely. Most of our professional DIN rail smart meters come with an RS485 port supporting the Modbus-RTU protocol for seamless industrial integration.
