Three-Phase Smart Meter, Direct Connection
The AE340 A Series for direct connection is a three-phase four-wire smart meter in the new AetherEdge™ enclosure. A plug-in 3G cellular or WB-PLC + RF module provides remote communication with the head-end system over DLMS/COSEM, and an internal load control switch supports load management. The values on this page come from the Rev1.0 user manual, a draft for approval.

Key features
- Plug-in remote communication module: 3G cellular (GSM/GPRS 2G and UMTS/HSPA 3G) or WB-PLC + RF.
- DLMS/COSEM implementation for interoperability with the head-end system, with encrypted communication data.
- Internal three-pole bistable load control switch, controlled by parameter configuration or by communication command.
- Four-quadrant measurement of active and reactive energy, with real-time power, voltage, current and power factor.
- Local and remote software upgrade; optical port with direct HDLC or IEC 62056-21 mode E.
Meter functions
Measurement
- Active energy import and export in kWh and reactive energy in all four quadrants; average voltage, current and power values.
Demand
- Current, average and maximum demand with a demand period of 60, 300, 900, 1800 or 3600 s; maximum-demand reset.
Instantaneous values
- Instantaneous values such as voltage, current, power and power factor.
Time of use and clock
- Time-of-use tariff management; quartz-crystal real-time clock with Gregorian calendar, kept running by the battery during a power failure.
Display and LEDs
- 8-digit LCD with auto, manual and power-down display modes; LED indications.
Billing and load profiles
- Billing period closed on any selected date; billing registers cannot be reset to zero; billing profiles and load profiles stored in the meter.
Load control
- Internal load control switch operated by the relay control logic; configurable limit values and limiters.
Events and alarms
- Self-diagnostic event log with time stamps; recorded signals (alarms); all meter actions are logged and can be read locally or remotely.
Security
- Encryption of communication data and DLMS/COSEM security set-up.
Firmware upgrade
- Local upgrade over the optical (IR) port and remote upgrade over the communication module.
Communication
- Optical port with direct HDLC or IEC 62056-21 mode E; slot for a plug-and-play communication module.
Battery and memory
- Lithium cell for the clock, cover-opening recording and display while the mains supply is off; low-battery alarm; battery replaceable without opening the housing; basic parameters stored in non-volatile memory with date and time stamps.
