EM280
Quick-fit sub metering solution
Benefits

Problem |
Solution |
---|---|---|
Easily manage complex configurations |
Configuration of advanced parameters is often a long task because menu navigation is complex and not intuitive |
UCS software helps you easily set all the parameters, permitting to save the configuration as a template and preparing it in just a click |

---|---|---|
Avoid recurrent setting of the sensor primary current |
Setting the primary current is a time consuming task and potentially a source of errors |
EM280 automatically detects the primary current value avoiding any manual setting and any potential error you might commit |
Avoid errors when installing current sensors |
Retrofitting an existing cabinet with split core sensors, or a new panel with standard CT leads, could be source of accidental connections on the incorrect phase |
With the 6 in 1 current transformer block, and its RJ12 connectors, you cannot make any connection mistake |

---|---|---|
Monitor multiple loads in existing cabinets |
Installation of many meters is often not possible for space reason |
With EM280 (4-DIN module) you can monitor six 1-phase loads (or two 3-phase loads), and display a virtual meter that sum the single consumptions. |

Solution |
---|---|---|
Limiting the p/n to be purchased, even if it is not known in advance what mounting type the next installations are requiring |
Managing too many part numbers is not effective, and limits the production flexibility. The needed quantity of each p/n cannot be predicted |
Thanks to its patented display, you can mount EM280 on DIN rail or on 72x72 panels. In addition, with the proper adapter, also 96x96 panel mounting is possible, so you can exploit even the existing hole of previous analogue meters, for example. |
