Product Description
1. Summary 1.1 DDSY8111Type Single-Phase Electronic Prepaid Kilowatt Hour Meter (IC card type) is developed on basis of DDS Type Single-Phase Electronic Kilowatt Hour Meter, by adding a data processing controller. In the meter, ADE 7755 measurement chip is used to convert electric signals into pulse signals, and microprocessor is used to process, to realize prepaid power consumption and control. This meter has functions such as anti-counterfeit, encryption, card reading, current limiting and automatic cut-off recovery on power supply circuit etc. Utilization of this type of Kilowatt Hour Meter will realize management of Prepaid power consumption for Government Power Supply Department. 1.2 This type of Kilowatt Hour Meter adopts direct-viewing wheel numeric counter to measure active power, and LED to indicate residual power, purchasing times and accumulated purchased power in Kilowatt Hour Meter. 1.3 Make and break of current circuit is controlled by relays. Therefore, to meters with maximum current under 40 A, direct connection is applicable, and to meters with maximum current above or equal to 40A, external control connection through current mutual inductor is applicable. (Control wire from meter controls external current relays or breakers to cut off current circuit). 2. Main technical data and specification 2.1 To this product, all power measurement characteristics and utilization conditions shall be in accordance with relevant requirements in China national standards such as GB/T17215-19981-Grade and 2-Grade Static AC Active Kilowatt Hour Meterand GB/T18460-2001,IC Card Prepaid Power Sale System. 2.2 When voltage of power supply is fluctuating between 80%-115% rated value, normal measurement will not be affected. 2.3 Specification of Kilowatt Hour Meter: 2.3.1 Reference voltage (V): 220V or 230V, 240V 2.3.2 Basic current and maximum rated current (A): 2.5(10); 5(20); 10(40) 2.3.3 Reference frequency: 50 Hz or 60 Hz Note: 1. Divided into two types, as direct connection type and external control type according to operating current. 2. Meters of special specifications can be made according to users requirement
