Characteristics

D000029326 en g – E450 PLC 1-phase ZCX100Px – User Manual
E450 meters have the following main characteristics:
•
Recording of active and reactive energy in all 4 quadrants with up to 6
rates
•
Data display on LCD
•
Measuring element in DFS technology (Direct Field Sensor) with
excellent measuring characteristics, including flat load curve, high
stability and good protection against interference.
•
Active energy measurement accuracy: Class 1 (IEC 62052-11/62053-
21) and MID accuracy classes B (EN 50470-1/50470-3)
•
Reactive energy measurement accuracy: Class 2 (IEC62053-23)
•
Wide range measurement from starting current to maximum current
•
Serial interface with optical input/output for automatic readout of data
on the spot and for service functions
•
Two-way communication to metering system with integrated PLC
transceiver
•
Wired M-Bus interface supports 1 multi-energy device (gas, water,
district heating)
•
Internal disconnector for full disconnection of energy, controllable
remotely from AMM system, or locally with a push button or via local
communication interfaces
•
Inputs and Outputs
- One digital input configured as S0, alert or local disconnector
command
2 relay outputs: Relay output 1 configured as solid state relay out-
-
put or mechanical on-off latching relay, relay output 2 as normal
open relay (inverse relay function supported for both relays)
•
Installation aids (e.g. phase voltage and direction of energy)
Presence of phase voltage (voltage value is displayed)
-
Visual output (creep indicator) on LCD
-
- Display of energy direction
- Wrong phase rotation indication
•
Anti-tampering measures
Detection of terminal cover opening
-
Detection of strong DC magnetic field
-
Detection of disconnector tampering
-
•
Storage of event information (e.g. power outages)
