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 zero, 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
