EM271
Quick-fit sub metering solution
Benefits
|
Need |
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 |
|
Need |
Problem |
Solution |
|---|---|---|
| Avoid recurrent setting of the sensor primary current | Setting the primary current is a time consuming task and potentially a source of errors | EM271 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 could lead to accidentally connect them on the incorrect phase | You can easily identify the correct current sensors through the L1-L2-L3 identification labels |

|---|---|---|
| Monitor multiple loads in existing cabinets | Installation of many meters is often not possible for space reason | With EM271 (4-DIN module) you can monitor two 3-phase loads (or six 1-phase loads), and display a virtual meter that sum (or the difference) of the 2 x 3-phase meters. |

|---|---|---|
| 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 EM271 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. |
