Single-Phase Static Carrier Electricity Meter (DDSI3699)

The instrument uses advanced MCU main chip FM2307 and carrier communication ASIC PLCI36C and special energy metering IC ADE7755 design, remote meter reading system in the terminal equipment, realized the power of accurate measurement of active users, and can use low-voltage power line as communication medium and installation of distribution transformer station in the area of concentration to maintain a reliable communication connection controller to half-duplex communication mode data such as its electrical energy transmitted to the concentrator, is the residential electricity consumption, implementing an ideal choice for remote meter reading.

Main Functions

1. Time-sharing measure: The function include positive and negative active electricity energy, quadrant reactive power.
2. Remote Meter Reading Power Line Carrier
The way software spread spectrum power line carrier communication, accurate, reliable, and copy reading ability.
3. Automatic relay function
4. Power storage
Store 2 to freeze the whole point of the data, 7-day freeze on the data, consumption data for 12 months, data transfer time can be set.
5. Energy measure precision, long-term work without adjustment
6. Infrared programming, programming power line carrier
7. LCD display and manual into automatic cycle show
8. Infrared programming, programming power line carrier
9. Infrared communication: The far-infrared port and instrument and meter programming
10. Freeze function
Monthly at 0: 00 on the 1st freeze last month, electricity, electricity power failure without loss of data stored in data storage unit. Daily freezing capacity can be maintained on the 7th, the whole point of electricity per hour to maintain.
11. The function of broadcasting time adjustment
23: 50 ~ 00: 10 not allowed in the context of the implementation of broadcasting school, they must only allow the school years on the same day when school hours to allow time.
12. Set the date & time by infrared and carrier.
13. Power can be cleared in not less then programming jumper, the battery does not allow more than 10kWh cleared, the following allows only clear power 10kWh 5 times, electricity will also clear the historical data clear; By the carrier or infrared can be the current capacity for arbitrary initial value, while clear historical data, but requires programming jumper to tie.
14. Input and output interfaces
