Product information

Description

The FF LE-03M-CT is a high-precision class 1 three-phase electricity meter engineered for accurate energy consumption monitoring in industrial and commercial environments. This device supports a programmable transformer ratio, allowing for flexible integration into various electrical systems. Equipped with an integrated LCD display, it provides clear and immediate access to energy data, while the built-in RS-485 MODBUS communication port enables seamless remote data transmission and integration into building management systems.

Advantages

This electricity meter stands out due to its high measurement accuracy, meeting class 1 standards, which ensures reliable data for billing and energy auditing. The programmable transformer ratio feature offers significant versatility, making it compatible with a wide range of current transformers. Furthermore, the inclusion of an RS-485 interface allows for efficient digital monitoring, reducing the need for manual readings and facilitating real-time energy management through centralized software.

Suitable for

  • Industrial energy management systems
  • Commercial building energy monitoring
  • Sub-metering in multi-tenant facilities
  • Integration with smart building automation systems
  • Energy auditing and efficiency analysis

When it may not be suitable

This device is not intended for direct measurement of high-current circuits without the use of appropriate external current transformers. It is also not suitable for residential applications where a simple, non-communicating meter is sufficient, as the advanced features like MODBUS connectivity may be unnecessary for basic household needs.

Key specifications

  • Measurement accuracy: Class 1
  • Phase type: Three-phase
  • Communication interface: RS-485 MODBUS
  • Display: Integrated LCD
  • Configuration: Programmable transformer ratio

How to use

The device should be installed on a standard DIN rail within an electrical distribution board by a qualified professional. Once mounted, the current transformers must be connected according to the wiring diagram provided in the technical documentation. After physical installation, the transformer ratio must be programmed via the device interface or the MODBUS protocol to ensure accurate readings. Once configured, the meter will automatically begin measuring energy consumption, which can then be monitored locally on the LCD or remotely via the RS-485 connection.

What to consider before purchase

  • Compatibility with existing current transformers
  • Availability of an RS-485 network infrastructure
  • Space requirements on the DIN rail
  • Technical expertise required for configuration

Usage recommendations

Ensure that all electrical connections are tightened to the specified torque and that the system is de-energized during installation to prevent injury or equipment damage. Regularly verify the integrity of the communication link to maintain consistent data flow.
