![]() Watts up? .NetManufacturer: Electronic Educational Devices This product is discontinued.
Watts up? are "plug load" meters that measure the amount of electricity used by whatever is plugged into them. Fast, intuitive and easy-to-use, Watts up? quickly and accurately measures any 100- 250 VAC device. USA models are rated at 120v. However, all models are available with IEC 320 universal outlets (UO) instead of integrated USA style cords. Click the more link next to each meter below to see a photo of the UO versions. Universal outlet versions are rated at 100v - 250v, 15 amp, 50/60 Hz, and are also CE marked. Cord sets are sold separately, with country/voltage specific ends. Be sure to order the UO model when completing your shopping cart. The meters incorporate sophisticated digital electronics that enable precise and accurate measurements in an easy-to-use format. State-of-the-art digital microprocessor design utilizes high-frequency sampling of both voltage and current measurements for true power. Power factor is captured so even phase-shifted loads such as motors are accurately measured. * Please note: We do not offer refunds or exchanges. 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 your internet (via home or office network) and the meter will automatically output data (see below for operation on private networks). Simply go to http://data.wattsupmeters.com/newacct.php and create a free account to access the data from your meter. You'll be able to see the live data in table format or graphically. The data can also be downloaded as a csv file. The meter can send data as fast as every second (fees apply for certain speeds - see membership level information). 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 even 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:
When using the .Net on a private network, be aware that the meter sends and receives data over port 80 but it can't output web pages. It is possible to assign the meter a static IP address, but it is not possible to enter that address into a web browser and communicate directly with the meter as many routers and modems do for configuration purposes. The data packet the meter sends is a raw data string and needs to be parsed and formatted. Our API specifies the format. Therefore, a web server application is typically used to collect the data and subsequently format the information. Normally, the .Net ships with the same memory as the PRO ES. The .Net is also available with double the memory with a purchase of 500 meters or more at one time. More memory is ideal for applications requiring logging for long periods of time. |
