Single-phase electronic energy meter DDS***8 was researched and developed ourselves, it's used to measuring the single-phase alternating current active power under the rated voltage **0V, frequency *0Hz. It has a independent modulation infrared light and first-class RS**5 communication interface; It's high-reliability, high-precision, long-life. It has widely voltage range and needn't to be adjusted. It's widely used in the singe-phase alternating current measuring situation in the city, village and factory single-phase alternating current.
Technical parameters:
Reference voltage: **0V
Reference current: 1.5A, 5A, *0A, *0A
Reference frequency: *0Hz
Basic error: It meets GB/T****5, *******8 requirements.
Starting current: ≤0.**4Ib
Creeping: When **5% reference voltage was applied to the energy meter and no current in the current circuit, the energy meter can not test to output more than 1pc impulse during the *0 times time when it generates 1 impulse under the rated voltage and starting current.
Power consumption: Voltage circuit power consumption(not communication status): ≤1W, 8VA.
Voltage circuit power consumption(communucation status): ≤3W, *2VA.
Current circuit power consumption: ≤1VA(under the Ib current)
Working temperature range: -*5℃~*0℃
Extremely working temperature range: -*0℃~*0℃
Extremely working temperature range of storage and transport: -*0℃~*0℃
Relative humidity: Annual average <*5%
*0 days(It's distributed in national way during a year)
It occurrs accidentaly in other days.
Atmospheric pressure: *3.0kPa~**6.0kPa(less than ***0m above of sea level)
Normal working voltage: 0.9Un~1.1Un
Extended working voltage:0.8Un~1.*5Un
Data record time after power cutting:≥ *0 years
Product life: more than *0 years
Product size: **2×**0×*8 mm
Weight: about 0.6kg
Power impulse width: *0±*0mS,Typical value: *0ms
Infrared communication rate: ***0bps
RS**5 rate: ***0bps
Communication protocal: according to DL/T*******7《multi-function energy meter communication protocal》and record documents.
