Three Phase Electronic Prepaid Kilowatt-hour Meter

1. Summarize
DTSY314/DSSY314 a new kind of static 3-phase prepayment kilowatt-hour meter, is used to measure 50Hz/60Hz three phase AC active energy, and at the same time, realizes the management of prepayment and load control. All the specifications are fit for standards of IEC61036-2000.
The meter integrates with micro-electron technology, computer technology and electric power measurement technology, so it has outstanding characteristics of high accuracy, high sensitivity, high stability, long life-span, low power consumption and multi-functions etc. It is the ideal choice to commercialize electric power and to standardize the management of electric consumption.
The meter should be installed inside house or in a box outside house with temperature from -25C to 60C, humidity less than 95%.
2. Functions and characteristics
