DDSF345型单相电子式复费率电能表是用于测量单相电网中额定电压220V频率为50Hz的交流有功电能，具有划分时段计量，分时计费，自动运算功能的智能计量仪表，用户可对不同时段的复费率进行用电选择。复费率产品的诞生，将改善了“峰时”用电，节省了电费，也使电能源得到均衡利用。 本产品可配备掌上电脑(抄表器)利用远红外进行编程，抄表校时，实现非接触式的数据传递，并与微机连接实行自动化管理。
DDSF345 type single――phase electronic multi――rate watt――hour meter is used to measure AC active electric energy of rated voltage 220V and frequency 50Hz of single―phase power network，it is a kind of intelligent measuring meter that can measure by means of divided―period，count the cost by time―sharing and calculate automatically．Users can make a decision of power utilization according to the multirate in the different periods．The bi rth of multi―rate products enhances electricity using at peak time，it not only saves the electricity cost，but also balances the electric energy using．After being equipped with a palmtop computer(meter reading system)，it can make use offar infrared to program，during meter reading and timing，it can realize nontouch type data transmission and automatic control by connecting with micro―computer |
