Three phase modbus prepaid energy meter DTSY844
DTSY844 electronic three-phase four-wire prepaid energy meter complies with the standards of GB/T17215.321-2008 andGB/T18460.3-2001. It uses advanced SCM processing system to collect, process and save data. Its purpose is to measure three-phaseAC active energy with a rated frequency of 50Hz or 60Hz.
Main features:
The application of computer management,
1.After the purchase of electricity.
2.After the use of electricity.
In the rated current range can limit the maximum use of power; a table one-card, electrical card can transfer data in both direction; automatic power off alarm users purchase electricity; electricity is zero , automatic power off; and has a certain anti-electricity software design.The meter is suitable for ambient temperature of -25°C~+55°C and relative humidity of no more than 85%.
Installation and use
1. The meter is inspected at the factory and printed in sealed form. It can be installed and used. If it is not sealed or stored
for a long time, the meter should be rechecked and sealed by the relevant department before installation.
for a long time, the meter should be rechecked and sealed by the relevant department before installation.
2. The meter should be installed vertically and without tilting in a dry and ventilated place. The floor on which the meter is installed should be fixed on a wall that is strong and fire resistant and not easily vibrating. The height of the meter is about 1.8m.
3. Wire the wiring diagram, tighten the wiring screw, and fasten the connection box inside the terminal box.
4. After the meter has been connected to the meter, the number of the meter must be multiplied by the transformation ratio, which is the actual number of energy.
5. One-table multi-card: The IC card held by the user should be purchased at the power supply department/the electricity sales office once it is lost.
6. Power purchase method: When selling power, insert the IC card into the IC card reader/writer, operate the computer at the same time, and write the user's number, pre-purchased power, etc. into the IC card.
7. Use of electricity cards: Insert the electricity purchase card into the card holder. If it is a valid card, the electricity meter will read the data into the table for about ten seconds. The LCD display screen will display in order: the number of electricity meters and the remaining electricity.
8. Operation display: During the operation of the meter, the LCD screen alternately displays the remaining power and total power consumption in the watch. The running meter IC card must be inserted in the meter's card holder, otherwise the meter relay will not pull in and the meter will not output, and the user cannot use electricity normally. After the user runs out of electricity, the IC card should be pulled out and stored properly
9. Power failure warning: When the remaining power is zero, the power meter will turn off the power failure warning and display the “trigger” prompt. At this time, the IC card will go to the power supply department to purchase power. After the power is purchased, the IC card is inserted into the card socket. On the restoration of power supply.

Product Knowledge
What is 3 phase electric meter?
The meter which is used for measuring the power of three phase supply is known as the three phase energy meter. The three phase meter is constructed by connecting the two single phase meter through the shaft. The total energy is the sum of the reading of both the elements.

What is the advantage of 3 phase over single phase
A polyphase system produces power at a constant rate in the load. A three phase system can transmit more power as compared to a single phase system. The efficiency of three phase operated devices and appliances is higher than the single phase operated machines. Three phase machines are less costly and more efficient.
