DDSY6611单相电子式预付费电能表(下称电表)采用微电子技术计量电能，符合GB/T17215.321-2008和GB/T18460.3-2001标准的电表，采用全屏蔽，全密封结构，用先进的单片机处理系统进行数据的采集，处理和保存，具有良好的抗电磁干扰，低自耗节电，高精度不需校表，防窃电，高过载，长寿命的特点。
电表应用计算机管理，机购电后用电。在额定电流范围内能限制最大使用功率(由供电部门限定)。一卡一表，专卡专用，失卡不失电，补卡再用。电卡能双向传递数据，能自动断电告警用户购电。电量为零时，自动拉闸断电，并具有一定的防窃电软件设计等。
电表配有RS485自动集中抄表接口，为即时采集用户预付费表用电情况，及远程拉、合闸控制用户用电提供了更有利的途径。
DDSY6611系列电子式电能表适用于频率50HZ或多或60HZ有功电能计量，安装于室内室外表箱使用。适用于环境温度为-35～80，相对湿度不超过85％，且周围空气不应有腐蚀性气体，避免尘砂，盐雾，凝露等影响。
DDSY6611 single-phase electronic prepaid electric energy meter
(hereinafter referred to as the meter)usesmicroelectronic technology to measure electrical energy, meets the GB/T17215321-2008 and GB/T184603-2001
standard electric meters, uses all shielded, fully sealed structures, and uses advanced single-chip processing system
for data collection, processing and preservation, and has good anti electromagnetic interference. It has low
consumption and electricity saving, high precision, no need to calibrate tables, prevent theft of electricity, high
overload and long life
The meter is managed by computers, and the power is purchased after the machine is purchased. Within the rated
current range, the maximum power can be limited (limited by the power supply department). One card, one watch,
special card, missing card, no electricity, card reused. The electric card can transmit data in two directions, and can
automatically cut off the electricity and warn users to purchase electricity. When the electricity is zero, the automatic
switch will be cut off, and some software for preventing theft of electricity will be designed.
The meter is equipped with RS485 automatic centralized meter reading interface, which provides a more
avorable way for the user to collect electricity in advance, and to control the users electricity use by remote pulling
and closing.
DDSY6611 series electronic watt-hour meter is suitable for measuring active energy of frequency 50HZ or more
or 60HZ. It is installed in indoor and outdoor case, Suitable for ambient temperature of-35-80, relative humidity
does no
