| 概述 Application（） |
| 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 s***es 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 tran***ission and automatic control by connecting with micro—computer |
