DDSY IC Card Single Phase Prepaid Meter With Electrical Metering System Management
Product Brief Introduction
DDSY150 Type Single-phase Prepaid Meter (hereinafter referred to as Electric Meter) adopts microelectronic technology to measure power energy in accordance with “IEC62053-21” Standard. With fully shielded, sealed structure and advanced single-chip processing systems for data collection, processing and preservation, it has features of good resistance to electromagnetic interference, low self-consumption of energy, high accuracy, proof against energy stealing, high overload and longevity.
Function and features
Computer management, prepaid feature; limitation for maximum use of power within the range of rated current (limited by the electricity supply department); one card for one meter, certain card for specific meter, lost card without losing power, reuse power after card remake. The IC card can transfer the data bilaterally; automatically alert power purchasing by cutting the power; automatically cut the power when the amount of power is zero. The meter is equipped with anti power stealing software.
