The prepaid energy meters support RF recharge (or card recharge) and remote recharge with many control modes, such as prepayment control and time control. The built-in 100A large capacity magnetic relay can realize internal switching and closing of the meter. It can also provide the dry contact output to control the external circuit breaker to achieve the trip function. It is widely used in pre-paid electricity management in commercial plazas, residential dormitories and school dormitories.
