Product DescriptionProduct DescriptionDDSY277 Main product featuresDDSY277 Single-phase electronic electronic prepayment energy meterThe DDSY277 Series Single-Phase Electronic Prepayment Energy Meter adopts a dedicated integrated circuit for energy measurement, and a CPU microprocessing circuit for data processing, storage, display, and electricity consumption control. Its main features include reliable performance, high accuracy, and low power consumption, along with RS485 communication, wireless communication, and prepayment functions. The product complies with the technical requirements for Class 1 energy meters specified in the standards GB/T18460.3-2001 and GB/T17215.321-2008.It is suitable for prepayment scenarios and remote centralized meter reading & billing applications, and is designed for measuring single-phase AC active energy in power grids with a rated frequency of 50Hz. The meter is equipped with a 7-digit LCD display with backlight; the backlight turns on when the meter is powered on or a card is inserted, and remains on during the first cycle of parameter scrolling display.Product CharacteristicsRated Voltage: 220VRated Current: 15(60)A (Note: "15" refers to the basic current, and "60" refers to the maximum rated current, which is a common expression for the current specification of electrical meters, indicating the meter can operate stably within the current range of 15A to 60A)Accuracy Class: Active Power Class 1.0Display: LCD 6+2 (Note: Means an LCD display with 6 main digits and 2 decimal digits, used to clearly show cumulative electrical energy values and other parameters)Frequency: 50HzPulse Constant: 1600imp/kWh (Note: "imp/kWh" is the abbreviation of "impulses per kilowatt-hour", indicating the number of pulses the meter generates when consuming 1 kilowatt-hour of electrical energy, a key parameter for verifying metering accuracy)Creepage: Equipped with anti-creepage logic design (Note: "Creepage" refers to the phenomenon where the meter registers energy consumption even when there is no actual load. The anti-creepage design prevents this false metering)Power Consumption: ≤ 6VA, ≤ 1.5WStarting Current: 0.4%Ib (Note: "Ib" stands for the basic current of the meter. This parameter means the meter can start accurate metering when the current reaches 0.4% of the basic current, reflecting the meter's sensitivity to small currents)Operating Temperature: -20~70℃Pulse Lamp: Pulse indication duration is 80 millisecondsAverage Relative Humidity: ≤90% (non-condensing)Beijing Hezhong Huineng Electric Co., Ltd. (abbreviated as: Hezhong Huineng), established in 2016 with a registered capital of 20 million yuan, is a national high-tech enterprise supported by the state, an innovative energy management enterprise, and a Beijing-based "Specialized, Refined, Unique, and Innovative" SME.Company ProfilePlease enter the title hereThis street light features high brightness, energy saving, environmental protection, and easy installation.
