Multi Tariff Three Phase Electric Meter LCD Display Energy Meter High Accuracy RS485
DTSF150 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
Temperature And Humidity Range
|Normal working temp||-25℃ ~ +60 ℃||Relative humidity||＜75%|
|Extreme working temp||-40℃ ~ +70 ℃||30 days natural distribution within one year||95%|
|Extreme transportation and storage temp||-40℃ ~ +70 ℃||Other weather condition||85%|
Power Consumption: When the meter is working on the reference current, temperature and frequency, active power,and apparent power in the voltage circuits should be no more than 1.5 W and 10 VA in the status of non-communication or no more than 3W,12VA in communication state.
LCD Display: 0～999999.99kWh
the capacity of long life li-battery installed into the meter is more than 1.2Ah, and there is no need to replace it during expected lifetime of the meter. It can keep the built-in clock working correctly for more than 5 yeas even there is no power. When the battery is short of voltage, the meter can send indicator and give an alarm automatically.

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.
d. Record the total times of opening the cover and the beginning and ending time of last ten case opening and data of energy consumption. The meter just records the earliest case opening during power failure.
