The AMI AS230 is a domestic Smart Meter which offers multi-tariff metering and flexible modular communications to interface directly to the utility via WAN or LAN and to connect to a consumer's Home Automation Network (HAN).

The module provides the platform for many different forms of communication’s including GSM/GPRS, PLC and Low Power Radio for WAN/LAN communications. Options for HAN communications can be included each as M-Bus or ZigBee.

The meter is fitted with a high contrast display that has an option to be backlit. Information can be displayed as English characters or OBIS identifiers. The meter measures import and export active energy, four-quadrant reactive energy and apparent energy. Extensive security features including main and terminal cover removal detection and magnetic field manipulation detection protect the meter and module from fraud or tampering.

The AS230 can be supplied with an SO output that mimics the test LED or a mains operated relay that can be controlled by the TOU rate.

Register readings can be received from up to three external meters. These can be Gas, Water, Heat or Electricity meters, up to four readings can be stored from each external meter.

Instrumentation values are available to aid meter commissioning. The meter records up to 120 days of load and instrumentation profile data.

Power Master Unit software provides a Windows™ graphical interface for programming the meter and reading meter data.

Meters can be supplied to meet EC Directive 2004/22/EC (MID): accuracy Class A or Class B. kvarh is to EN62053-23 Class 2 or 3.

The meter has an ingress protection rating of IP53 to IEC60529:1989.
