I. Main feature
The DDS196 Single Phase electronic Energy Meter consist by measure
Module and cell. This type meter have high credibility, LCD display.
This type meter also have high accuracy and high load, long life.
It is best choose for this type of meter.
II. Function and feature
- measurement by active, the total electricity data display by wide LCD.
- it has pulse output, photo electricity output
connection port. The wide of the pulse is about
80ms±20ms.
III. Main technical data
The meter accord with the GB/T17215-2002 (Class 1 and 2 quiescence
AC active energy meter technical requirement.
3.1 Specification
Type | Precision grade | Standard voltage (V) | Standard current(A) |
DDS196 (LCD) |
CLASS 1 | 220V | 1.5(6)A 2.5(10)A,5(20)A,10(40)A 15(60)A, 20(80)A, 30(100)A |
Note: the current such as 1.5, 2.5, 5A is the basic current( Ib), the 6, 10,20A is the Max current( Imax)
3.2 Technical data
3.2.1 Basic error
Current | Power factor(cosφ) | Error limit % |
0.05Ib | 1 | ±1.5 |
0.1Ib | 0.5L | ±1.5 |
0.1Ib-Imax | 1 | ±1.0 |
0.2Ib-Imax | 0.5L | ±1.0 |
3.2.2Start current: when the meter under the rate voltage ,frequency and power factor is 1 , the load current is 0.004Ib, the meter work normally.
