DDS6611 single-phase electronic watt hour meter (liquid crystal display) is the electric energy measurement product developed by the company. It is used to measure the AC active power of the rated voltage 220V and frequency 50Hz. It has independent modulation infrared light port and 1 way RS485 communication port. The meter has the advantages of high reliability, high precision, long life and so on. It adapts to wide voltage range, and the whole machine needs no adjustment after leaving the factory. It can be widely used in urban, rural or factory enterprises for single phase AC power consumption.
产品特点
1、计量功能
具有正、反向有功电能计量功能，并能存储其数据，反向有功电量计入正向有功电量中。
2、通讯功能
具备远红外通讯或485通讯功能。
3、设置和清零
电能表出厂后不能设置底度，不能清零。
4、显示功能
a)液晶常显累计用电量，显示电能值的单位为kWh，数值显示位数为6位，小数位1位。
b)电能表使用高亮、长寿命LED作为指示灯；
脉冲指示灯：红色，平时灭，计量有功电能时闪烁。
5、脉冲输出
1. Measurement function
It has the function of reverse active energy metering and can store its data. The reverse active energy is counted into the forward active energy.
2. Communication function
It has the function of far infrared communication or 485 communication.
3. set up and clean up
The meter can not be set up after the factory is released, and it can't be cleared.
4. Display function
A) liquid crystal display cumulative power consumption, showing that the unit of energy value is kWh, and the number of digits shows 6 bits and decimal places 1 bits.
B) the power meter uses high brightness and long life LED as the indicator.
Pulse indicator: red, usually extinguished, measuring active power when flashing.
5. Pulse output
The electric energy meter has the function of LED pulse and electric pulse output which are directly
