Three-phase cellular card electricity meter, hereinafter referred to as the instrument, measuring electricity USES the microelectronics technology, in line with the GB standard table, adopts full block, fully sealed structure, with advanced single chip microcomputer processing system for data acquisition, processing and preservation. Has good resistance to electromagnetic interference, lower the consumption of electricity saving, and high precision without correction table, preventing electricity-stolen, high overload, long life, small size, beautiful appearance, convenient installation, etc.

After instrument application of computer management, machine electricity purchasing power. Can limit the scope of rated current maximum use of power. A card table, specialized CARDS, card without losing electricity, fill card again. Power point card can two-way transfer data, it can automatic warning users to buy electricity. When power is zero, automatic switch power, and have certain preventing electricity-stolen software design, etc.
