KNX single-phase secondary electricity meter

DIN-Rail mount modules

CODE: EK-MS2-TP-TA

Description

What cannot be measured, cannot be improved: Ekinex supports the energy efficiency of buildings with its Smart Metering solution. The KNX single-phase KNX Secondary Electricity Meter from Ekinex is a device for measuring active and reactive electrical energy with bidirectional counting for imported and exported energy, current, voltage, active and reactive power, power factor and other electrical parameters. The 2 measuring circuits available are for connection via external current transformers. The device has an integrated communication module to the KNX bus.

The meter provides electrical parameters on the KNX bus, has total/partial counters, comparators and other logic functions, and is configurable via ETS for integration into the energy management system with functions such as load control or threshold monitoring. The device is designed for installation in flush-mounting boxes or inside switchboards and control cabinets (with the supplied accessory).

Technical data
  • Supply voltage: 230 V AC
