DDSY2031single phase electronic prepaid meter

1.Application:

DDSY2031 series single phase electronic prepaid meter is researched and developed by CHIQI electric. It is the latest microelectronics that is infrared RS485 communication. It is automatic computer fee management hardware attachment IC card. The function like: Power electricity calculation, electricity price management,loading control, electricity consumption collection,etc. If you want to use electricity, you must buy power fist. This prepaid meter working with RS485 and IR infrared meter readying system port. That is easy to collect the information of user power consumption.It is use to measure frequency 50/60Hz single phase AC electricity power.

2.Function and feature

• Double measure function, it can test anode and cathode energy current power and accumulated one way current consumption, so that it has function of anti-theft electricity. It will get feedback for next time electricity power buying.

• The meter working will IC card, one meter one card, the user can buy electricity power by themselves. It is not necessary to read meter door to door and collect the fee indoor. It carry on buying electricity first and then use power.

• The meter mainly calculate the electricity power up to power consumption fee amount.

• It can preset the electricity price freely. It will satisfied with different customer group.

• Double warning remind function:When the user IC card money finish or less than the meter min amount, the meter will show warning.If the balance amount is less than power off amount, the meter will make current power off and remind user fill the money in the card.

• LCD display the user power consumption amount, balance amount, electricity unit price.

• It has fault self-checking function, when the fault happened, the meter will display the relative warning.

• It adopts magnet relay, lower power consumption, high reliability.

• LED indicator, the meter output pulse signal. It is reliable and stable, it is not necessary to check for long time working.

• It has function for power off protection. The data never lose when the electricity power off, it can keep 100 years. When it power on, the data will recovery

• The IC card socket have function of self-protection.When the wrong iron thing push into the card socket, the card reading will be self-protection, it is not influence other function.Make sure the meter can not be damaged.

• This meter is small mass, light weight, high accuracy, lower power consumption, wide loading, convenient installation.

• It can select RS485 infrared communication port, the communication agreement is according to DL/T645-1997, DL/T645-2007, Modbus-RTU
