product description
DDSUY5333, DTSUY5333 electronic prepaid infrared 485 communication remote power-on/off/local electricity sales rail-type watt-hour meter is our company adopts the latest microelectronic technology, using IC card as the medium of electricity purchase and supplemented by electricity fee collection computer management automation software and hardware technology , With multiple functions such as electric energy metering, electricity price management, load control, electricity information mobile phone, etc. At the same time, it realizes the electricity consumption management system of first purchasing electricity and then using electricity, and realizing the intelligent all-electronic electric energy meter for the commercialization of electric energy. In addition, the electric meter is equipped with RS485 and IR infrared automatic centralized meter reading interface, which provides a more favorable way for real-time collection of the electricity consumption of the user's prepaid meter.
This meter is suitable for measuring single-phase AC active energy with a rated frequency of 50Hz or 60Hz.
This meter is for fixed installation indoors. It is suitable for ambient temperature not exceeding -30~+85℃, relative humidity not exceeding 85%, and the air does not contain corrosive gases and avoids the influence of dust, mold, insects, etc.
● The two-way metering function can accurately measure the active electric energy in the positive and negative directions, and accumulate in one direction, with the function of preventing electricity theft, and will feed back the change information to the electricity sales management system when purchasing electricity next time.
● Use IC cards and cooperate with advanced encryption technology to ensure that one meter and one card are used. Users can purchase electricity by themselves, and do not need to visit meter reading or charging. The implementation of the implementation of the first purchase of electricity and then the use of electricity.
● The electric energy meter is mainly based on the amount of electricity used, and the unit price of electricity is deducted for every 1 kilowatt-hour of electricity, and the remaining amount in the meter retains multiple decimals to ensure that the user's interests are not lost.
● The flexible electricity price setting function allows different users to adopt different electricity prices to suit the current special user group.
● Double-layer alarm prompt function, when the user's pre-purchase amount is used up, that is, when the remaining amount is less than the displayed alarm amount, the meter will give a visual warning. When the remaining amount is less than the alarm amount, the user will be tripped and cut off to remind the user to purchase electricity.
● The LCD screen displays the remaining amount, accumulated electricity consumption, unit price of electricity, credit amount, and card number (last 6 digits) in turn.
● It has perfect multiple fault self-checking functions, once a special fault occurs, the meter will display the corresponding notice to remind the user to eliminate the fault.
● Adopt new high-current magnetic latching relay, low power consumption and high reliability.
● L uses the electrical isolation technology to output the pulse signal of the electric energy calibration meter, and the light-emitting diode indicates the power consumption, which is stable, reliable, and does not need to be adjusted for long-term work.
● It has a reliable power-off protection function, the data will not be lost after power-off, it will remain unchanged for 100 years, and it can be restored after power-on.
● IC socket self-protection function, when metal pieces and other foreign substances are inserted into the IC socket, the card reader part is automatically protected but does not affect normal measurement and other functions, ensuring that the electric energy meter will not be damaged.
● This product is small in size, light in weight, high precision, low power consumption, wide load, easy to install and use.
