Multi-functional 3 phase meters
ENVIS application on PC.
SMN additional features:
SML33 and SMM33 instruments are electronically and functionally identical and its only difference is its mounting option. SML33 is intended for a DIN rail mount. SMM33 is intended for a 96mm cut hole installation (in panel). SMN33 instruments supports additional features such as registration of maximum demand and fourth (PEN) current evaluation.
Three voltages (230 VRMS and three isolated current inputs (5A and 1A nominal secondary current, supports measuring CTs) can be measured. Optionally the low current high ratio solid core and split core metering CTs can be ordered. The later option has an advantage in that its operation is much simpler and the measured circuit need not be interrupted during installation.
Data Acquisition and Processing
SMM, SMN and SML instruments can optionally be equipped with a remote communication port (RS485, RS232 or Ethernet). As such it can be connected to any SCADA software with Modbus TCP or Modbus RTU protocol support. ENVIS software is supported and can be used to configure the instrument, to read out actual data from connected instruments. It stores them in archive or database and creates reports and analysis.
