COUNTIS E1x

Active energy meters

Single-phase – direct 63/80 A

COUNTIS E12 - MID COUNTIS E13
COUNTIS E12 – MID COUNTIS E13
Function
  • The COUNTIS E1x is a modular active electrical energy meter displaying the energy and power consumed (kWh and kW) directly on its backlit LCD display. It is designed for single-phase load metering and is used for direct connections of up to 63 or 80 A depending on the modele).
  • COUNTIS E12, E14 and E16 have MID certification.
Advantages
RS485 communication (MODBUS or M-BUS) or pulse output
  • To enable the remote reporting of energy consumption, COUNTIS E1x are provided with either a pulse output or an RS485 communication output, with MODBUS or M-BUS protocol. In addition to their reporting functions, COUNTIS E1x with RS485 can be configured remotely and enable access to multi-measurement values.
Dual-tariff metering
  • Two tariffs are available and can be easily accessed through the meter’s display. Each tariff can be utilised to assign energy metering to different time slots (high and low demand hours) or different sources (normal/backup).
MID certified B+D module
  • COUNTIS E products with MID certification provide the guaranteed accuracy required for applications in which sub-billing of the electrical energy consumed is necessary. “Module B+D” certification guarantees that the design and manufacturing process of products are approved by an accredited laboratory.
