The AS220 AMI domestic Smart Meter offers multi-tariff metering and modular communications to interface directly to the utility via a Wide Area Network (WAN) or Local Area Network (LAN) and to connect to a consumer's Home Automation Network (HAN).

The module provides the platform for many different forms of communications including GSM/GPRS, PLC and Lower Power Radio for WAN/LAN communications. The modular and optical port can be used to read data from any meter connected to the HAN.

The meter measures a combination of import and export active energy, four-quadrant reactive energy and apparent energy. Extensive security features protect the meter from fraud or tampering.

The AS220 meter records up to 120 days of load profile data for one channel (15 minute period). Instrumentation values are available to aid meter commissioning. An additional feature observes the network regarding power quality.

The meter is supported by the user friendly reading, configuring and programming tool alphaSET.

Meters can be supplied to meet EC Directive 2004/22/EC (MID): accuracy Class A or Class B. kvarh is to EN 62053-23 Class 2 or 3.

The meter has an ingress protection rating of IP53 to IEC 60529:1989.

Display Programmable display sequence with OBIS identifiers. There is an option to back light the display.
