The three-phase guide rail prepayment meter is mainly used in the field of electrical energy management for three-phase four-wire networks with frequencies ranging from 45 to 65Hz. It can measure the electricity information in the power grid and exchange data with the upper computer through encrypted IC cards or 485 communication. The built-in high-power relay of the instrument can achieve local tripping and closing operations, thereby achieving prepaid functions.
Users can set the internal parameters of the electricity meter according to the actual situation on site, which is convenient to use, simple to operate, and high in accuracy; Widely used in various residential areas, intelligent buildings, market malls, collective dormitories, schools, and other fields.
The primary current specification within 100A is a direct input type, without the need for an external circuit breaker. The on/off operation is achieved through the built-in relay of the instrument; The primary current specification is greater than
At 100A, an external current transformer and circuit breaker are required, and the circuit breaker is controlled through the dry contact signal output by the instrument to achieve on-off operation.
The product meets the relevant standards of GB/T17215 and GB/T17883, and is an ideal electricity meter for reforming the traditional electricity consumption system and improving the level of electricity management.
