The SDM630-MT is Multi-tariff RS485 Modbus Din Rail Three Phase Multi-function Energy Meter.

The multi-tariff function is widely used to measure the energy consumed in different time zones. It supports max 4 tariffs and 10 time segments, the tariffs and segments can be set via RS485 communication. The unit measures and displays the characteristics of 1p2w, 3p3w and 3p4w supplies, including voltage, frequency, current, power, active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh.

The meter has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU. The instrument traceable number is 0120/0151.
