CHINT 313280 DTSU666 – 3-phase MID energy meter with RS485

The CHINT DTSU666 (Art. 313280) is a reliable 3-phase energy meter for the precise recording of electricity consumption. Thanks to MID certification (Class B), the device is ideal for applications where traceable and reliable energy billing is required.

Product features

  • 3-phase energy meter for exact consumption measurement
  • MID Class B (˜ 1% accuracy) – approved for billing-relevant measurements
  • RS485 interface (Modbus) for connection to energy management systems
  • Ideal for photovoltaics, self-consumption, ZEV, wallboxes and sub-meters
  • Compact design for installation in the control cabinet
  • Reliable recording of energy consumption (kWh)

What does MID Class B mean?

This meter complies with MID Class B, which corresponds to an accuracy of approx. 1%. This makes it ideally suited for most applications such as PV systems, tenant electricity, wallbox billing or sub-meters.

Higher classes such as MID Class D (˜ 0.2% accuracy) are mainly used in industrial or grid operator applications. For typical building installations, Class B offers the optimum combination of accuracy and economy.

Interface & integration

The DTSU666 has an RS485 interface with Modbus protocol. This allows the meter to be easily integrated into energy management systems, inverters or smart home solutions (e.g. for PV monitoring or load management).

Areas of application

  • Photovoltaic systems (self-consumption / feed-in)
  • ZEV / combination for self-consumption (Switzerland)
  • Sub-meter for residential or commercial use
  • Charging stations / wallboxes
  • Energy monitoring and consumption analysis

Note

The meter is MID-compliant and is suitable for many billing-relevant applications. Please observe the local regulations and the requirements of your network operator.
