single phase electronic prepaid meter
Directions For Use
I usefulness,specialty and appliance range
DDSY1986single phase electronic prepaid meter (prepaid meter)adopt micro-electron technique amount energy
power,which conforms to IEC62053-21:2003 and GB/T18460.3
-2001 standard meter,adopt full-screening ,full-sealed
structure,has advanced monolithic process system to conduct picking,processing and reserving data,assuming favorable specialty of repelling electromagnetic
interference,low consumption power savings,high accuracy & no checking meter,anti-thieve electricity,high load,long life.
Main specialty:apply computer management,buy electricity in advance then use it;it could limit the most used power at rated current range;a card of a meter,only one card of the meter,not loose electricity once loosing card,feed card to use;card transitive data two-way,automatic disconnect to warn user to buy electricity;the electricity amount is 0, automatic disconnect the electricity;It has definite anti-thieve electricity software design, etc.
DDSY877 series electronic energy meter used for 50Hz or 60Hz active metering power,installed indoor or in outdoor meter box.The surrounding temperature is between -10℃ to +50℃,relative humidity is not exceed 85%, and there is not putrid gas, in the same time, it should avoid the effect of dust sands, salt fog, dew, etc.
II,specification and main technical parameter
5(20) A,10(40) A,15(60) A
Basic error margin
0.05 I b
0.1I B~ Imax
0.1 I b
Note:1,Ib is rated current,Imax is rated max.
2, Starting current:at the condition of rated voltage, frequency and power:class 1.0 meter is 0.004Ib, class 2.0 meter is 0.005 Ib.
3, Running with no-load:when circuit has no current and the voltage is 115% rated voltage,output pulse is not more than one.
4, Power consumption:≤2W,10VA
III,Main structure and work principle
1, Main structure
Adopt inflaming ABS shell,solid,sealed,good shielding property.
2, Work principle
First voltage divider gains voltage sampling
signal,diverter take current sampling
signal, through multiplier to get voltage & current production signal,then frequency
transform to generate scaling pulse which is a product between frequency and voltage & current .
Watt-hour meter work principle:
3, Data process
Energy amounts pulse through photo-electricity coupler send to CPU process,after operation store non-easy-lost EEPROM. Computer manages information system, through IC card reader,put into some amount and monitored IC card input micro-processor system, after CPU operation, then supply display,warning,disconnection
