Features
1.Wide load range ; high accuracy , reliability and sensitivity; low power loss.
2. Bi-directional measuring, accurately measure the active energy of both forward and reverse power.
3.Passive pulse output interface with optocoupler isolation.
4. Infrared communication interface. Baud rate is fixed at 1200.
5. RS485. Baud rate is 1200, but it can be set at 600 ,1200,2400, 4800 or 9600.The meter collects data in a convenient and reliable way by connecting to a concentrator which communicates by GPRS.( This function is optional.)
6. Relay to control the switching on/off of the load. ( This function is optional.)

DDS28-1 | Class 1 | 220V,230V | 3(9)A,5(20)A, 10(30)A,15(60)A, 30(90)A,50(120)A |
Load current | Power Factor | Elementary error(%) |
Class 1 | ||
0.05Ib | 1.0 | ±1.5 |
0.1Ib~Imax | 1.0 | ±1.0 |
0.1Ib | 0.5(lag) | ±1.5 |
0.8(lead) | ±1.5 | |
0.2Ib~Imax | 0.5(lag) | ±1.0 |
0.8(lead) | ±1.0 |
Applications
1.Starting: when reference voltage, reference frequency and power factor is 1.0, the meter of class 1 under 0.4%Ib, the meter can start and do measurement normally.
2.No load running: the meter has anti-shunt running logic circuit. when voltage circuit plus 1.15 times reference voltage, and there is no current in current circuit, the test output of meter is supposed not to have more than one pulse.
3.Power consumption：≤2W（5VA）
4.Environment condition
5.standard working temperature：-25℃～70℃
limit of working temperature：-25℃～80℃
note: Special requirement of working temperature limit：-40℃～80℃
6.Working Principle
The measuring chip samples the voltage and current signals and converts them into pulse signals which are proportional to energy. The signals are transferred to MCU chip to do the accumulation measurement, and output in passive pulse with optocoupler isolation. MCU and exchange and communicate data with the outside world meanwhile.
