DTSD450/DSSD450 series Three Phase Electronic Kilo Watt Hour Meter - DTSD450

Energy Meter

Electronic Multifunction Energy Meter DSSD450 is a new generation product that can measure reactive energy and active energy with multitafiff, it is designed by modularization, it multi functions can combine freely to meet users requirement.

Mainly technology data:
1. Class index: Active energy class 0.5 1 reactive energy class 2
2. Closck error less than 0.5s/day
3. Reference temperature 23 degree
4. Data protaction data stored time after power off more than 10 years
5. Conditionas working temperature -20~45 degree
Ulmost working temperature -25~55 degree
Relative humidity less than 85 %(with environment temperature 23 degree )

Main functions:
1. Measurement function
Can measure active energy and reactive energy respectively and have separeate active and reactive pulse signal output interface
2. Multi tariffs
A. Four tariffs ten time intervals
B. Calendar for a century (1996-2095) can switch automatically
C. Record and store the total active energy and reactive energy and active energy and reactive energy under kinds of tariffs
3. Demand statistics
A. Recod active max demand and its occurring time
B. Demand statistics adopts slip method
C max demand is stored as per month
D. Automatically alarm and trip for overload
4. Record voltage loss
A. Record 9 voltage loss and information of power failure also can record their initial and restoring time
B. Record total active energy and reactive energy of no voltage loss phase
5. Programming and meter reading
A. RS485 communication interface
B. The programming and meter reading are performed by RS485 communication interface, infrared communication interface and palm computer, also it can perform meter reading through remoted controller and alternation displaying
6. Meter reading at zero oclock
A. The setting day for meter reading is 1 st -28th of every month the meter can calculate and store the data in the last month at zero oclock of setting day
B. Can store and dispaly calculated data for past three months at the same time
7. Meter reading at power off
The meter is provided with individual meter reading batteries so it can finish meter reading at power off
