Introduction
DTSY794 Type Three-Phase Electronic Prepaid Energy Meter adopts microelectronic technology and comply with technical requirements for single phase electronic watt-hour meter stipulated in GB/T 17215.321-2008 and GB/T18460-2001. It apopts fully shielded, fully sealed structure and uses advance SCM processing systems for data collection, process and preservation...It also features good resistance to electromagnetic interference, low self-consumption of energy-saving, high accuracy, without calibration, burglar-proof electricity, high overload and long life etc...Meanwhile it provides fully functional managements software system of selling power.
Functions and features
1)Computer manage the system,users must purchase the electricity before use.
2)Active single-phase electric power metering,no subject to adjust in terms of long working
3)Function of transfer,cancel account,tempoary stop and rebate electricity bill(Especiall apply for comercial users)
4)Once the electric consumption available out,it should be cut off automatically.
5)Cut off power supply when over load
6)Fault self-diagnosis function,the diagnosis range from load switch,EEPROM TO THE IC CARD DATA
7)Support large capacity of reading meter,once card can read 160 users electricity consume data
8)Large screen LCD Display
