WATTS UP.Net Power Analyzer/Watt Meter USB Interf. SM-EE-WU-72222

WATTS UP.Net Power Analyzer
Watt Meter (USB interface)

Using the device is simple. Plug the Watts Up Monitor into a three-prong grounded electric outlet (the monitor is on a 6 foot long cord to make it easier to view the display). Plug the device to evaluate into the top of the monitor. The monitor will immediately display the wattage demanded by the electrical device. If the monitor has left plugged in for a period, it will display the cumulative amount of electricity consumed or the cumulative cost of the electricity used (based on your local electric rate).

Internet enabled AND power switching! With all the capabilities of the PRO, the .Net goes even further. Ideal for remote monitoring, the built-in web server allows data to be accessed via the internet. Connect the meter to the public internet (via home or office network) and the meter will automatically output data.

You'll be able to see the live data in table format or graphical. The data can also be downloaded as a csv file. The meter can send data as fast as every second (extra fees may apply for certain speeds). Connect a wireless adapter (for example the Dlink DWL-G730AP or the TrendNet TEW430APB, both configured in client mode) into the meter's ethernet port, and the meter can be used wirelessly.

In addition, the .Net introduces active energy savings. With an internal switching relay , the .Net can turn off power to the end load based on user configurable rules. Rules can be based on single or multiple meters. These rules and their associated application include:

Time of day: Effective when your utility has TOU (time of use) rates, where they charge a higher rate during peak times.
Peak usage (watts): For commercial accounts, which are typically charged a surcharge if their consumption ever surpasses a peak threshold during the billing month. Having multiple .Net meters can enable you to simply and economically "shed power" and keep you under the threshold. For example, connect 10 meters to your account, and configure our website to automatically turn off specific loads when the total power across all ten meters exceeds a threshold you designate.
Cumulative usage (wh): Use for tiered pricing rates, when higher usage is billed at a higher rate.
Manual on/off: For security reasons, rebooting servers, or while on vacation.

Normally, the .Net ships with the same memory as the PRO ES.

WATTS UP.Net Power Analyzer/Watt Meter Specifications:

Higher ratings of 100-250v, 50/60Hz, and 15 amps require the universal outlet (UO) version. The electronics in the meter are capable of 20 amps but the cord and receptacle have different ratings. Verify the rating on the cordset you are purchasing.
