COUNTIS E0x

Active energy meters

Single-phase – direct 32 A

COUNTIS E02 - MID COUNTIS E04
COUNTIS E02 – MID COUNTIS E04
Function
  • The COUNTIS E0x is a modular active electrical energy meter displaying the total energy consumed (kWh) directly on its LCD display. It is designed for single-phase load metering and is used for direct connections of up to 32 A. The COUNTIS E02 and E04 has MID certification.
Advantages
Compact
  • The COUNTIS E0x is only 1 module wide.
Pulse output
  • The pulse output enables the kWh consumption to be reported to a remote system (PC/BMS) so that it can be analysed for billing, energy saving or energy cost management purposes.
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.
