SXY14DRS-32A / SXY12DM-32A DIN Rail Single Phase MID Smart Energy Meter (RS485 / M-Bus)

Single-phase MID-certified smart energy meter designed for compliance-driven and integration-oriented metering environments. Supporting RS485 (Modbus) or M-Bus communication, it enables reliable remote monitoring and system-level data collection.

The meter provides accurate measurement of voltage, current, frequency, power and active energy. A white backlit LCD ensures clear readability across installation conditions.

With a compact 1-DIN modular design (18mm width), the unit is optimized for distribution panel integration and space-constrained installations. It is suitable for residential, EV charging, industrial and utility applications requiring structured monitoring and communication capability.

MID certified in accordance with EU Directive 2014/32/EU (Certificate No. 0120/SGS0207), supporting deployment in regulated markets and compliance-based projects.
