DD862 typeSingle-phase electric energy meterIt is a widely used induction type AC energy meter in China. This product is a series of products jointly designed by the whole country. After nearly 20 years of production, use, and technological improvement, the product's performance is more stable and reliable. This product has passed the international authoritative organization KEMA test in the Netherlands for the first time in China and is used to measure single-phase AC active energy.
Products with bidirectional metering, pulse output, carrier communication and other functions can be provided according to user needs.
1.1Single-phase electric energy meterMain Purpose and Scope of Application
DD862 single-phase energy meter induction energy meter, used for measuring single-phase AC active energy with a reference frequency of 50Hz Its technical specifications comply with the provisions of GB/T15283-1994.
1.2Single-phase electric energy meterEnvironmental conditions for use
The electric energy meter is fixedly installed for indoor use, suitable for ambient temperatures of -10~+50 ℃, relative humidity not exceeding 85%, and there should be no corrosive gases in the surrounding air to avoid the influence of dust, salt spray, condensation, etc
2.Single-phase electric energy meterInstallment and use
2.1Single-phase electric energy meterThe electric energy meter shall be inspected and sealed with lead before leaving the factory. Before use, the lead seal should be checked for completeness before installation Electric energy meters without lead seals or stored for too long must be re inspected by authorized departments before installation and use
2.2Single-phase electric energy meterFix with three screws, drill holes in advance according to the installation size of 140X105mm as shown in the diagram, and ensure that the deviation of the electric energy meter from the vertical position after installation and fixation does not exceed 1 degree
2.3Single-phase electric energy meterIt is necessary to strictly follow the wiring on the cover plate of the terminal box. The incoming wire connected to the terminal box should use copper coins, and the cross-sectional area should ensure that the current carrying capacity per square millimeter is not greater than 5A. The fixing screws must be tightened to avoid burning due to poor contact or thin leads
2.4Single-phase electric energy meterWhen transcribing electrical energy, attention should be paid to the reading of the meter. The numbers in the red box are decimals, the numbers in the black box are integers, and if there is no red box, they are all integers Example 5 (20) A, a red box shows a previous meter reading of 00885, which is 88.5 kWh, and a subsequent meter reading of 01248, which is 124.8 kWh, resulting in an actual electricity consumption of 36.3 kWh
3.Single-phase electric energy meterWarranty
From the date of sale by our company, if the user fully complies with the transportation, storage, installation, and use regulations of the electric energy meter and the electric energy meter does not meet the requirements of GB/T15283-1994 under the condition of complete lead sealing by our company, our company promises to return the unqualified product within three months, provide replacement within one year, and provide warranty within three years.
