Single / three phase active energy meter rail DT802 Description DT series power meter is mainly used to measure the low voltage network, with high precision, small size, easy installation, and other advantages. Flexible installation in distribution box, to achieve energy sub-metering for different areas and with different loads, statistics and analysis. Function measure positive and negative direction active energy, "←" is displayed on behalf of energy in the opposite direction. The total energy, sharp, peak, flat, valley were accumulated. Stores the current and historical power last three months of data, power data is not lost in the table. Clock and time rate: clock error in 0.5s / day, with a calendar, timing and leap year automatic switching function; can be set tip, peak, flat, valley four kinds of rates. 10 day time period can be set, the minimum time interval is one minute. Display: 7-bit wide temperature type LCD display; can display data wheel significant, significant time round 4s; energy pulse is indicated by LCD lights. Programming, meter address settings; time and date settings; rates set period of time; the power the base zero setting. Display Description: Under normal operating conditions, the meter cycle time, date, address table, the total power, sharp power, peak power, battery level, valley power, total reverse power, total electricity consumption last month, last month pointed electricity last month peak power, the power level last month, last month, and day time table valley power. 485 can be achieved when the data reading and meter settings.
