Liberty 310

Liberty 310 is a three-phase token-less smart meter for pay-asyou-go and managed credit applications. Encrypted vend codes are used to transfer credit between the online vending system and the meter. Liberty 310 maintains its own energy account, which supports multi-rate tariffs with features such as public holidays and 'friendly credit' periods.

The meter interfaces with an In-home Display (IHD), which provides real-time and historical information on consumption and accounting. Consumers can readily see how much energy they are using, how much it is costing (per hour), how much credit is left and how long it will last, based on the current rate of consumption. Liberty 310 also provides historical data, enabling comparisons such as 'this month against last month' to be made.

Liberty 310 is highly resistant to magnetic fields and electrostatic discharge (ESD), making it ideally suited to aggressive environments, particularly where revenue protection (RP) is a concern.
