< 1. Purpose, characteristics and scope of application
, <
,
, < The electronic single-phase prepaid electric energy meter (hereinafter referred to as the electric meter) uses microelectronic technology to measure electric energy and complies with B/ - and B/- standard electric meters adopt a fully shielded and fully sealed structure, and use an advanced single-chip processing system to collect, process and save data. They have good anti-electromagnetic interference, low self-consumption and power saving, and high accuracy without calibration. It has the characteristics of meter, anti-electricity theft, high overload and long life.
, < Main features: Apply computer management, purchase electricity first and then use it. The maximum power usage can be limited within the rated current range (limited by the power supply department). One meter and one card. Special card. No loss of power if the card is lost. The replenished and reused electricity card can transmit data in both directions, automatically cut off the power and alert the user when the power purchased reaches zero, automatically shut down the power and have certain anti-power theft software design.
, .< series electronic energy meters are suitable for frequency or active energy measurement, and can be installed in indoor or outdoor meter boxes. It is suitable for use when the ambient temperature is -+℃, the relative humidity does not exceed, and there should be no corrosive gases in the surrounding air to avoid the effects of dust, sand, salt spray, condensation, etc.
