Product Description
The WattsOn-MCM is a modular, internet-accessible metering solution for up to 60 independent circuits. It houses
between one and twenty metering "nodes", which measure three independent circuits each. The device measures Volts,
Amps, Real Power, Voltage Angle, Power Factor and Frequency, and Watt-Hours. These parameters can be read per-
channel, or aggregated into user-defined groups.
The WattsOn-MCM may be purchased with as few or as many nodes as needed, and additional cards can be added at a
later date if additional circuits are needed. Nodes are "hot-pluggable", meaning they can be added or removed without
powering off the device, ensuring metering is not interrupted.
It provides a dynamic AJAX-enabled web-interface to configure the device and to display readings, and can also send its
data to a web server via HTTP POST at regular intervals, using a highly configurable template-based format. The
WattsOn-MCM will store a backlog of data in the event of short, temporary network outages to ensure any post
information is not lost.
The unit accepts up to 600V (line-to-line) directly without needing potential transformers. It may be configured for use
with 333mV output CTs or
mA output CTs (such as Elkor’s "safe" mA split and solid core CTs)
.
The WattsOn-MCM supports DHCP. A Windows® utility is used to detect and configure the network parameters from a
Windows PC. In addition, the web interface allows for full device configuration.
For developers, custom web pages may be uploaded onto the device to create custom, highly integrated user interfaces.
