| three-phase electronic pre-paid watt-hours meter Appearance and installation size Tupe：DSSY8888/DTSY8888 Product number: LTCBY1 Weight：about 1.7kg ☆ Product Brief Introduction Three-phase electric pre-paid watt-hours meter is a new type of IC
card pre-paid meter, which has such function as power metering,
load control and customer information management. It is an ideal
product when reforming electric-use system, achieving electrical
energy to commercialize, setting charge and adjusting load stage in
the electric network. All the indexes comply with the technological
specifications aiming to the three-phase electronic pre-paid
watt-hours meter in the standard of GB/T18460.3-2001 and
GB/T17215-2002. This series electronic watt-hours meter has two
ways to connection: Direct connect or connect by current
transformer ☆ Function and features 1. Measure active three-phase electric power, no subject to adjust
in terms of long working. 2. Three-phase power supply can assure accurate metering in case of
cut off in one line(each line of the three-phase and three line) or
two lines(any two line of the three-phase and four
line)，Measuring accuracy is not influenced； 3. Assuming function of defect phase indication or voltage
indication； 4. There is electric energy that tests the signal to export； 5. Each meter responds to a card, well protect from forgery； 6. electric power quality is approaching the alarming power
quality, the digital tube should be lighted to remind user of
timely purchasing； 7. Once the residual electric consumption is out, it should be
cut-off automatically；； 8. Overload and cut out automatically, the convenient electric
department holds again； 9. There are data that write the function, the convenient electric
department manages； 10. It is installed outside the form that the on-load switch
adopts, adopt the relay to control in the form (the capacity of
contact is 250VAC/5A)； 11. The IC card power selling control system has the function as
power selling and using control ☆ Specification and Technical Data 1. Rated
Current(A)：3×1.5(6),3×5(20),3×10(40),3×15(60),3×30(80),3×30(100) 2. Rated Voltage(V)：Three-phase four-wire 3×220/380V or 3×57.7/100V Three-phase Three-wire 3×100V or 3×380V 3. Rated Frequency(Hz)：50,60 4. Accuracy class：class 1.0, class 2.0 |
