2.0 PRODUCT OVERVIEW
Thank you for choosing the Jetlun Panel Meter (RD77724). The Panel Meter is an
integrated Zigbee enabled metering device that provides phase-based energy
measurement. Removing the guesswork, the Jetlun Panel Meter provides a detailed
breakdown of your entire home’s energy usage in real-time helping you understand
where your energy is being used and if you have renewable energy sources, the Panel
Meter calculates how much energy you are adding back to the grid in real-time so you
know where your money is going. It measures energy usage from within existing electric
service panels avoiding the costly installation of subpanels and associated wiring. The
Panel Meter is designed for use in demand side management (DSM), sub-metering, and
energy monitoring applications.
The Jetlun Panel Meter works with 0.333 VAC solid-core and split-core current
transformers (CTs). Split-core CTs offer greater ease of installation, because they can
be installed without disconnecting the circuit being measured. Solid-core CTs are more
compact, generally more accurate, and less expensive, but installation requires that the
measured circuit be disconnected. Although you can source and use off-the-shelf CTs
with the Jetlun Panel Meter, it is highly recommended to use CTs from Jetlun because
those CTs have been calibrated and tested to work with the Jetlun Panel Meter. Using
third-party CTs will affect the accuracy of the measurements.
