COUNTIS E63

Active energy meters

3 x single-phase – Direct 100 A

COUNTIS E63
COUNTIS E63
Function
  • The COUNTIS E63 is a modular active electrical energy meter which provides metering for three single-phase loads, with direct connection of up to 100 A. It directly displays the total and partial energy and power (kWh and kW) consumed by each single-phase load.
Advantages
Compact
  • Due to the integration of three single-phase meters in the same case (7 modules wide), the COUNTIS E63 provides significant space-saving.
Advanced multi-measurement functions
Advanced multi-measurement functions are available via RS485 MODBUS communication:

  • Instantaneous currents: I1, I2, I3
  • Instantaneous voltages: U1, U2, U3
  • Instantaneous power: 3P, 3S
  • Instantaneous power factors: 3PF
  • Load curves for each of the 3 phases: Viewing of average positive active power consumption over a programmable period.
Detection of connection errors
  • The product is protected against phase/neutral inversion and detects wiring errors. This simplifies the installation and commissioning, thereby reducing associated costs, and ensures that the device operates correctly.
