DDS1278 Type Single Phase Electronic Watt hour Meter

 

Product Description

DDS1278 electronic single-phase watt-hour meter is the latest product of our factory,according to GB / T17215-2008 standards for production,used to measure the rated frequency of 50Hz,rated voltage of 220V single-phase AC active energy.The product uses metering power dedicated large scale integrated circuit and SMT technology,to ensure measurement accuracy and reliability,in order to make the data after the power failure is not lost,use the LCD counter.

Start

Electricity meter in the reference voltage, reference frequency and COSΦ = 1.0 conditions,when the load current is 0.004Ib (primary table) or 0.005Ib (secondary table),the meter can still work .

Creep

When the meter without current,the voltage is 115% of the rated value,the meter should not record the power(Creeping circuits with logic).

Power consumption

The overall machine consumes less than 2W / 5VA.

Main structure and working principle

The power consumed by the user,through the divider,the signal on the shunt is sampled,to the amplifier and multiplier circuits,after integral and V/F conversion product signals,dividing the logic circuit output,drive the frequency-type meter or drive the LED display to measure the power.

Select

According to the maximum actual use of power by the user,make a reasonable choice of the above specifications,to correctly record power consumption,choose the specification is too big or too small,will cause the meter degrees or fever burned and so on.

Installation and wiring

1 Before the Watt-hour meter go out factory they would pass the test,and stamped with seals,you can install and use.

2 The meter should be installed indoors,the bottom plate of the mounting meter should be fixed on a sturdy, refractory wall,recommended installation height of 1.8 meters,use ambient temperature at -20 ℃- + 55 ℃,relative humidity is not more than 85%,there should be no corrosive gases in the air.

Transport and storage

1The transport and disassembly of the watt-hour meter should not be subject to severe shocks,should be based on ZBY003-1984 "instrumentation packaging technical conditions" and GB / T15464-1995 "instrumentation technical conditions" provisions of the transport storage,and according to the box "up" requirements placed.

2Keep the  meter in the original package,the preservation of the local ambient temperature is 0 ~ 40℃,relative humidity is not more than 85%,there should be no corrosive gases in the air.

 

3The  meter preserved in warehouse,should be placed on the bench,stacked height is not more than five boxes,unboxed after a single  meter stack height is not more than 10.

Guarantee period

From the factory within 18 months,due to our factory on the manufacturing quality problems do not conform to the requirements of the national standard of electric meter,and seals intact,the factory will provide free repair and replacement.

Attention

1,Electricity meter pass strict inspection before they go out,qualified seal after stamping,the user shall not be removed,otherwise the factory does not bear any responsibility for the meter.

 

2,The meter as well as other electric products,can not be put on hold for a long time,especially in the rainy season to prevent damp moldy.
