Product details
SDM630MCT Series
Advanced, multifunctional three-phase electricity meter for DIN-rail mounting, designed to work with current transformers (CT 1A/5A or optionally 333 mV). The device offers bidirectional measurement of energy and network parameters, a high level of accuracy and MID B+D certification. With flexible communication options, it is ideal for modern energy consumption monitoring systems in single- and three-phase installations.
Key features of the SDM630MCT Series:
- Versatile measurement: Supports single-phase (2-wire) and three-phase (3- and 4-wire) installations with bidirectional measurement of active and reactive energy.
- MID B+D certification: Compliance with the EU directive 2014/32/EU (SGS certificate) ensuring the legality of billing.
- High accuracy: Available accuracy class 1.0 for active energy (standard) or optional class 0.5 in selected models.
- Flexible communication: Built-in pulse outputs and optional RS485 Modbus RTU or M-Bus ports for remote data reading.
- Multi-parameter and multi-tariff: Measurement of parameters such as voltage, current, active, reactive and apparent power, frequency, power factor and support for multiple tariffs (in selected versions).
- Easy installation and operation: Compact DIN-rail enclosure 72 mm wide, IP51 protection rating and a clear backlit LCD display.
Who is this a good choice for?
The SDM630MCT Series is an excellent choice for building managers, energy auditors and installers of home and industrial automation systems who need a reliable and precise tool for submetering and monitoring electricity consumption. Thanks to MID certification, a wide range of communication interfaces and easy DIN-rail mounting, the device performs perfectly in commercial, residential and industrial applications requiring remote collection of measurement data.
