Main Specification

Wireless Energy Meter Node

Sub-meter which calculates several electrical parameters
with pre-wired split core current transformers (CT)
and embedded wireless data transmission.
The Wireless Energy Meter Node is a single and 3-phase
electric meter with a wireless (radio) communication.

1. LED Indicator
2. Antenna
3. Current Transformer (CT)

- Energy Meter : Active, reactive and apparent
energy per phase and sum with a time-stamp.

- Recording Interval Meter : Active, reactive and
apparent energy per phase and sum with a
time-stamp of the end of the recording interval;
minimum voltage per phase and maximum
current per phase during recording interval;
frequency

- Meter Identi cation and Con guration : Meter
con guration and version; recording interval
Time setup, command and status word.

A Respect the Current Transformer phase allocation according to Voltage phase allocation.
->If the phase allocation is wrong, the Wireless Energy Meter Node will send incorrect energy data.

B Make sure that the arrow (3) shows the way of the positive current flow from the generator to the load. In this case, the label (6) is facing the load.
->This allows the Wireless Energy Meter Node to calculate Active Energy with the right sign.

C Close the Current Transformer C mer a round the cable (1)

D Use the mounting clip (5) to attach the Current D Transformer on the cable (4).
