1.Introduction
DDS7666 Series front board mounted single phase electronic active energy meter is widely used in measuring the power consumption for residential, offices shops, etc. This meter adopts advanced ultra- -low power loss integrated circuit technology and SMT technique. It can accurately measure 220V 60Hz active energy consumption from single phase AC electricity net. The meter completely accord with relevant technical requirements stipulated in the International Standards 1EC62052-11 and IEC6205321 for Class 1 and Class 2 single phase active energy meter
It has following features: Wide load, high accuracy high reliability high sensitivity stable error curve,small volume, light weight, low power loss, high overload specious appearance convenient installation etc.
Specification and main technical specification
| Item/Type | DDS7666 |
| Accuracy Class | Class 1 .0,Class 2.0 |
| Reference Voltage | 220V |
| Basic Current (Max Current) | 1.5(6)A、2.5(10)A、 5(10)A、 5(30)A、 10(40)A、15(60)A、 20(80)A、 30(100)A、 |
3.Starting and Creeping
When the meter reference voltage reference frequency and power are at 1and the load current is at 0.4%Ib (Class 1.0), 0.5%Ib (Class2.0), the meter should starting and can measure continuously.When voltage circuit is 115% of reference voltage and no current through the current circuit the output pulse of the meter should not more than 1 pulse.
Basic Error Range
