Efergy Transmitter only, add CT clamps if required

This item does not include CT (Current Transformer) sensor clamps. For it to take measurements you will need to add these CT clamps if you don't already have the same type.

How many sensor clamps do I need?

If you are measuring single phase, add one clamp per transmitter. If you are measuring a three phase circuit, add three clamps per transmitter.

Your energy monitor will display one total reading per transmitter, regardless of how many clamps are attached.

Works with Efergy E-Max only

This Transmitter can be used in conjunction with the Efergy E-Max only. It does not work with the older Efergy Elite or Efergy E2 energy monitors.
