===== Applications =====

  * Digital multi-function power sensor for single/three phase networks

===== Features =====

  * DIN rail mounting
  * Three Phase 100A Direct Fed
  * Accuracy Class 0.5 (Active Energy)
  * Bi-directlonal Measurement for kW and kWh
  * Configurable Pulsed output (Import/ Export/Nett kWh)
  * Line Frequency
  * Power, maximum power demand and power factor
  * Active energy imported and exported
  * Reactive energy imported and exported

===== General description =====

SDM630 series measures and displays the characteristics of 1p2w, 3p3w and 3p4w supplies, including voltage, frequency, current, power, active and reactive energy, imported or exported, harmonic etc. Bi-directional measurement makes it an ideal choice for Solar PV measurement. The units support Max. 100A direct connection, saving the cost and avoiding the trouble to connect external CTs. Two pulse outputs and 1 communication port (Mbus/Modbus) are provided for remote monitoring. The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
