Product Introduction: Prepaid energy meter is also called quantitative energy meter and card energy meter. In addition to the measurement function of ordinary electric energy meters, the special feature is that users buy electricity first and then use it. If the user does not continue to buy electricity after using up the electricity, the power supply will be automatically cut off. The code-based principle is as follows: the management system combines user information and electricity purchase information to generate a set of encrypted codes, which the user inputs into the meter. After correct decryption, the meter obtains the pre-stored power or amount and saves it. Main technical indicators, accuracy level: .level, in line with B/-, 3-, current specifications, rated voltage: , rated frequency: , starting current: .b, power consumption: ≤ , environmental working conditions: -℃～+℃ , the 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℃).
