The track-type three-phase pre-paid energy meter is primarily used in the energy management field for three-phase four-wire networks with frequencies ranging from 45 to 65Hz. It can measure power information in the power grid and interact with the upper computer through encrypted IC cards or 485 communication. The meter is equipped with a high-power relay that allows for local disconnection and connection operations, thereby enabling pre-paid functionality. Users can set the internal parameters of the energy meter according to the actual situation on-site, which is convenient and easy to operate. It is widely used in various residential, smart buildings, collective markets, dormitories, and schools. The direct input type for the primary current specification within 100A does not require an external circuit breaker; the on/off operation is achieved through the meter's internal relay. For primary current specifications greater than 100A, an external current transformer and circuit breaker are required; the on/off operation is controlled by the dry contact signals output from the meter. The product complies with GB/T17215 and GB/T17883 standards and is an ideal energy meter for reforming the traditional electricity consumption system and improving electricity management levels.
