Product Description
DDS155 single phase electronic watt-hour meter uses imported specific large-scale integrated circuits and other advanced technology.It can measure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz.
It can measure forward and reverse active power accurately and it calculates accumulatively in the same direction.
It can prevent electric larceny at the same time.
It outputs heartbeat through optical couple. LED displays electricity consumption,so that it si easy to control.
Functions:
1. Standard configuration 5+1 digits display(99999.1kWH)by step motor and pulse machinery counter. May select 6+1 digits display-Configuration one port of pulse output passive(polarity).
2. Two led instructions power state and signal of power impulse.
3.Automatic detect the direction of the trend of load current. And onely yellow led display when working,this is meaning the load current reverse.
4.Single direction single component measure single phase two wire active power consumption. It is nothing with direction of the trend of load current. 5.Complying with standrad IEC62053-21.Direct connect and use, there are two types you may select.
6.The power dissipation is less than 0.5w when power supply 120v, and power dissiptaion less than 0.8w,circuit dissipation less than 0.5VA while power supply 120V, which is much higher standard than IEC 62053-21.
7.Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use electricity safely;
