Product overview of prepaid energy meters: Prepaid energy meters are also called quantitative energy meters and card energy meters. In addition to the measurement function of ordinary energy meters, the special feature is that users buy electricity first and then use it. If the electricity is used up, If the user does not continue to buy electricity, the power supply will be automatically cut off. The main parameters of the prepaid energy meter:, Accuracy level: ., in line with B/-, 3-, Current specifications, Rated voltage:, Rated frequency, Starting current: ., Power consumption: ≤ , Environmental working conditions: - ℃ ~ + ℃, relative humidity does not exceed (temperature + ℃), working voltage: within the ± fluctuation range of the reference voltage, it can work normally. , Power consumption: ≤. , Display: digit + multiplied by the indicator light, the remaining power meter in the meter displays the accumulated power consumption. , Control relay contact capacity: AC/3/. , The working environment temperature is: -℃~+℃. , Relative humidity of working environment: ≤ (temperature is +3℃).
