Energy Tracking’s WEM-MX Enhanced
JULY 07, 2008

Energy Tracking is announcing the release of a unique version of the WEM-MX meter. This new version will allow the the use of current transformers that provide a 333mV secondary output (Safe-CTs). One of the major advantages of this version is that the current transformers are available in split-core versions that are much lower in cost versus split core current transformers that provide a 5 amp secondary. In addition, the cost of a shorting block is also avoided.

The WEM-MX combines revenue grade electric metering accuracy and an Ethernet enabled solution for two way communications and reporting. This smart Internet enabled energy meter provides a superior solution with the ability to be accessed in real time via a standard web browser and be configured to send consumption, demand and load profile reports via email and ftp. More details are provided below.
