Single-phase electricity meters

DDSFI846 Single-phase electronic plural rate carrier electricity meter Functions and features 1.The meter is equipped with accurate measurement of active power, and negative power energy can be counted into accumulated positive active energy, this meter has best error linearity. 2.Three tariffs for electricity consumption: peak load hours, day hours and low load hours, and built-in automatic clock switching service on the time tariff and for a calendar switching between the time and leap year. 3.All the data can be stored for over ten years during power off. 4.Equipped with infrared telecommunication connector. Reading of the following data can be performed with the aid of infrared communication done by hand-held terminal: current consumption for total, peak load hours, day hours and low load hours as well as consumption foe total, peak load hours, day hours and low load hours for last month. 5. Reading of the working data can be performed through RS485 communication connector. 6.Automatically recording system can perform the work as reading the date from distant meter and switch off the power through power wiring based on the site of meter. 7. LCD liquid crystal indicator displays the information as follows: data, time, site, constant, current consumption for total, current consumption for peak load hours, current consumption for peak load hours, current consumption for day hours, current consumption for day hours and current consumption for low load hours.
