KIT with S711E power meter and three Rogowski coils with the same lenght. The wide display gives clear and fast information about the plant. This KIT is an innovative instrument for measurement and recordings of the electrical parameters. It is particularly suitable for consumption analysis and control, with an excellent quality/price ratio. Connections are very quick and easy, very useful for retrofitting applications on existing switchboards or for energy audit. S711E (Energy Plus) equips 8 MB of memory, allows the reading of min/med/max values of all the powers active/reactive and calculation of harmonics up to the 15th. On request, the instrument can communicate through RS485 serial port with ModBUS RTU/ASCII or via LAN port with ModBUS TCP protocol.
