panel-mountRS-485digital

DDS155F Single Phase Multi Tariff Energy Meter DDS155(F) is a new-designed single phase multi-tariff energy meter on the basis of State Grid standards to meet the requirements of building "a comprehensive strong and smart grid" This meter adopts ultra-scale digital processing signal processor chip, permanent date storage memory,full-isolated RS485 communication port and remote infrared as well as the wide LCD display; The advanced SMT process have been used into the meter and aII the elements inside have the features of durable life,high insulating strength and corrosion resistance with its high intensity, anti-flame and beautiful structure. It is integrated with all the functions of energy measurement, information storage, processing and interaction . Functions and Features: 1. Electricity Measurement Measure positive direction active energy and reversed direction active energy. Time-sharing measurement: the active energy consumption is accumulated and saved corresponding to the point, peak, smooth and trough period. total quantity should not use the summation method by adding up each tariff or consumption quantity of each period. 2. Reset 1) Clear up the data stored in the meter, such as energy consumption, frozen quantity and event records etc. 2) The reset operation should be recorded as event permanently to prevent from being operated by unauthorized person. 3) Bottom value of distortion meter must be reset and cannot be programmed any more.
