A smart meter that can be used universally in 1-phase alternating current (1p2w) as well as 3-phase alternating current networks (3p3w 3p4w) with a variety of measuring and display options.
Its small width of only 4 division units with simple snap-on installation for 35mm DIN rails and its large load range of up to 100A make this device a direct measuring all-rounder.
The legibility of the clear and illuminated display, in addition to the simple and direct operation, is only one of the countless advantages. In addition, the SDM630-Modbus-V3, as its name suggests, offers an RS485 Modbus interface for remote reading and remote maintenance, as well as 2 pulse outputs for supply or delivery, which in turn makes it an ideal companion in photovoltaic technology.
Offered here in the version with revised display and hardware, as well as the net active power output in kWh and reactive power in kVArh Total calculated from import-export, which can also be read out as an additional register via Modbus.
Application examples:
- primarily suitable for photovoltaic applications due to the two S0 pulse outputs for supply and delivery as well as via RS485 Modbus for remote query and remote maintenance
- Energy management systems, test measurements of distributions
- Wear monitoring on machines, service life determination of systems
- consumption determination of heaters or pumps
- control and distribution construction, control technology
- for test measurements in confined spaces
- building automation, air conditioning, CHP
- switchgear construction, trade and installation trade
- Consumption monitoring at camping sites, holiday apartments, garage complexes,
offices, sublets, granny flats
- general consumption measurements in/of sub-distributions suitable for billing to third parties
-
