The COUNTIS E5x is a panel mounted active and reactive electrical energy meter displaying energy and multi-measurement values directly on its large backlit LCD display. It is designed for utilisation on three-phase or single-phase networks with connection via CT and is suitable for applications of up to 6000 A. The CT ratio can be configured by the user via the keypad and the display, or via RS485 MODBUS communication (E53).","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.","Direct display of multi-measurement and metering values","Multi-measurement • Currents: instantaneous: I1, I2, I3 • Voltages: instantaneous: U1, U2, U3, U12, U23, U31 • Power: - instantaneous: 3P, 3Q, 3S - maximum average: 3P • Power factor: - instantaneous: 3PF Metering • Active energy: +\/- kWh • Reactive energy: +\/- kvarh • Apparent energy: kVAh
