APPLICATION

DSM866CF thre phase four wire active electronic multi-tariff watt-hour meter,LCD display.
The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.
The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique,the key components and part all adopts long life type.
The meter is widely used in office buildings, shopping malls, residences, airports and metro,etc
The meter has function of different tariff measure for different time period.

FUNCTIONS AND FEATURES

? Measurement function:
1. Measure bidirectional active energy; (reverse energy is calculated as positive energy), and store its data.
2. The total, sharp, peak load,level /day hour and valley /low load electric energy are separately measured and stored.
3. The communication, time zone switch, repeated power out and on, will not affect the measurement accuracy of the meter.
4. Store multi-tariff energy data of 12 months including current month, data transfer store dividing-line time is automatic read meter date. Can freeze and transfer store the data of electric energy on any hour of any given day between 1st and 28th in each month.
5. Data is stored in EEPROM when power cut, and data can be kept for more than ten years.
? Period of time and rate function
1. Program set sharp,peak load, level/day hour, valley/low load 4 rates 10 period of time, from small to large array. The minimum period of
time interval is 1 minute, period of time set can span clock zero.
2. Random period of time start and stop real time and set time error not more than 5s
3. Adopting inset crystal hardware clock circuit, with temperature compensation circuit to ensure under the normal working conditions, the
time error of clock to be within 30s/month .Automatically adjust the time, date and lunar year automatic transfer,
4. The power of it is supplied by a separate lithium battery in order to maintain the working when power cut. With the capacity of more than 1.0Ah and a long life time over 10 years, the battery can continuously work more than 3 years.
? Display and surveillance
1. Large wide temperature (-30ºC--80ºC) LCD display ;
2. 8 digit LCD display, 6 integer and 2decimal;
3. Display the data of current date, time/ current total, sharp, peak load, day hour, low load energy, etc. LCD display recycled. After energy meter connect electricity, date, time, current total, sharp, peak load, day hour, low load , operating period of time(peak load, day hour, low load) etc. will display recycled, displayed content can be set . The default time of display interval is 5s. The data displayed can be set according to the requirement, the most can be set up to 32 items.
4. Has the function of remain LCD display recycled after pressing the button after power cut. The time displayed will be the same as before pressing the button. LCD would not display if not press the button in 20 seconds.
? Communication function
1. Handheld terminal or PC via infrared communication or RS485 communication, complete programming settings and meter reading.
2. -Infrared communication interface: communication distance ≥4m,
-Communication angle: ≥±15o
3. RS485 communication: baud rate 1200bps/s,semiduplex, RS485 communication circuit is separated with inner meter circuit, communication distance:1200m. Electric parameter is conform to DL/T645-97.
Through RS485, can realize remote read meter operating situation.
? Output function
1. Pulse testing with active output port (to meet the requirements of Remote pulse output, pulse width 80ms ± 20ms).
2. A clock output. In the electricity supply, the clock output terminal on the output of one second signal, the signal optical isolation for the
detection of (optional)
3. With RS485 output, RS485 Meter Reading can be realized.
? Event logging function
1. Can record the total MID of active power consumption and the time when it happens during the current and last two months
2. Can record the time of the last programming and the times of programming.
