VMBKWH18 - Single phase energy meter for din rail mounting, 5 (80) a, connectable to vmb7in

This single-phase DIN rail kWh meter is part of a new generation of single-phase electronic watt-hour meters, adopting micro-electronic techniques, LSI circuits and advanced digital and SMT techniques.
The meter is in conformity with the relevant technical requirements of Class 1, Class 2 and IEC62052-11, IEC62053-21.
It accurately and directly measures 50/60 Hz active energy consumption from single-phase AC electricity grids.
This module can be connected to the Velbus installation by using a VMB7IN, 7-channel input module.


  • Only a qualified professional may carry out the installation in conformity with in force legislation and standards.

  • protocol manuals for developers
