Track-type Single-phase Pre-paid Electric Energy Meters are primarily used in the field of electrical energy management for single-phase networks with frequencies ranging from 45 to 65Hz. They can measure electricity information in the power grid and interact with the host computer through encrypted IC cards or 485 communication. The meter is equipped with a high-power relay (80A) for local opening and closing operations, enabling pre-paid functionality; users can easily set internal parameters of the meter according to the actual situation on-site; simple operation; widely used in various residential areas, smart buildings, markets, collective dormitories, and schools, among others. The track-type single-phase pre-paid electric energy meter is a direct-input type, with an input current of 80A. The product complies with GB/T17215, GB/T17883 standards, and is an ideal meter for reforming the traditional electricity supply system and improving electricity management levels.
