20A CT Sensor (ID 7.8mm)

EMS energy monitors use CT sensors to monitor current. The sensors connect to the analog inputs on the energy monitor, of which there are three types:

  • Source (SRC) channels SRC1&2 on the standard unit and SRC1,2&3 on the Pro unit
  • Sub Circuit channels CH1~8 on the standard unit and CH1~16 on the Pro unit.
  • All channels on the Ecomon unit.

For the Ecofront and Ecofront Pro the SRC channels and the sub circuit channels serve different functions – they measure current in different ways and therefore use different sensor types.

For the Ecomon all channels can be configured to monitor any combination of mains or sub-circuits.
