The E460 3-Phase smart prepayment meter, offers point-to-point communications for low density installations (e.g. farms, small holdings, etc). The meter has an open standard DLMS/COSEM RS485 communications port with the SG108 under cover modem or an external modem of your choice. Most importantly, the E460 3ph meter retains its integrated G3-PLC communications to the DC450 Data Concentrator and Head-end System and to the in-home P160 Customer Interface Unit.

FEATURES

• The E460 portfolio consists of single-phase, DIN-Rail smart, single phase British Standard (BS), three-phase STS prepayment meters which works with a P160 PLC Customer Interface Unit
• Integrated OFDM G3-PLC for two-way communications between the E460 meter, the P160 Customer Interface Unit and the DC450
• Data Concentrator communications via WAN to the Head-end System (HES)
• The single-phase BS and three-phase meters offer optional point-to-point communications via their under-cover modems which support LTE/NBIoT with 2G fallback – this is especially valuable to low density installations such as farms and small holdings.  The meters have integrated G3-PLC communications so that they may also be used with the G3-PLC Data Concentrator where the density of meter installations justifies installation of the Data Concentrator.
• Open STS prepayment (IEC62055-41/51) dlms/COSEM
• Changeable meter account modes such as post-payment (credit) or prepayment with either STS consumption (kWh) or STS monetary currency unit options

FUNCTIONS

• Zero power tamper sensing when meter is not powered
• A wide range of events with date and time stamps in the on-line mode
• Power quality profiles instantaneous values of voltage, current, power and much more
