SDM630-Modbus V2 DIN Rail Smart Meter for Three-Phase Electrical Systems
The SDM630 Series is a three-phase multifunction 100A direct fed DIN rail mounted electricity meter. It can measure and display the characteristic of 1p2w ,3p3w and 3p4w supplies, With a user friendly menu navaigation and highly visible LCD display, it The SDM630 requires Mains Voltage inputs (live in and live out, neutral in and neutral out) in order to operate, it is self-supplied so does not require an external auxiliary supply. We have a range of options from a pulsed output version for cost savings and Modbus RTU combined with dual pulsed outputs or MBUS also combined with dual pulsed outputs. Finally, we also have an option for multi-tariff.
