COUNTIS E5x

The COUNTIS E5x is an electrical energy meter designed for three-phase networks. It is used for connection via CT up to 6000 A.
The COUNTIS E50 is a totalising meter allowing direct reading of the power consumed, using a pulse output. Two partial meters with reset allow the energy to be metered over a specific period.
The COUNTIS E53 uses JBUS/MODBUS communication via RS485.

Advantages

RS485 MODBUS communication or pulse output
To enable the remote reporting of energy consumption, COUNTIS E5x are provided with either a pulse output (E50) or an RS485 MODBUS communication output (E53). Remote configuration of the Countis E53 is possible via RS485 MODBUS communication.

Detection of connection errors
The COUNTIS E5x is protected against phase/neutral inversion and has an integrated test function which can be utilised to detect wiring errors. This function enables CT installation errors to be corrected without having to remake connections. This simplifies the installation and commissioning, thereby reducing associated costs, and ensures that the device operates correctly.

Large backlit LCD display
Thanks to its large backlit LCD display and its multiple viewing screens with direct pushbutton access, COUNTIS E5x provide clear readings and are easy to use. They directly display a number of total/partial metering and multi-measurement values : +/- kWh, +/- kvarh, kVAh, I, U, V, S, PF, etc.
