Standalone 2 Wire Prepaid Electricity Meters Anti - Fraud Prepaid Power Meters
The DDSY168-I is a standalone 2 wire one phase prepayment meter. It is built with the lowest cost but comprehensive metering features. It is finished in a compact and keypad-based BS8565 standard housing and maintains IP54 rating, providing a cost-effective solution of prepayment. Credit dispensing to service providers.
The credit data is transferred to the meter via a 20-digit numeric token code that is generated by Standard Transfer Specification (STS) encryption protocol. The code is entered into the meter via a keypad.
The DDSY168-I allows for payment control settings. Landlords or service provider can input emergency credit, power limit, daily or monthly limitation, debt collection policy, etc via token code into the meter. And the meter will provide valuable information such as daily usage, monthly usage, demand record to consumers for them to budget their electricity consumption.
