Detailed Product Description

1.Product Brief Introduction

Three-phase electric pre-paid watt-hours meter is a new type of IC card prd-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 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 wiring:Direct wiring or wiring by current transformer.

2.Function and  features

1) Active three-phase electric power metering,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 & three line) or two lines(any two line of the three-

phase & 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)Once  the  remaining  electric power quality is approaching the alarming

power quality, the digital tube should be lighted to remind user of timely purchasing
7)Once the electric consumption available is out, it should be auto.Cut-off
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

contol
