DEM151 single phase prepayment watt hour meter

DEM151 single phase prepayment watt-hour meter is a kind of mechanism-electronic integrative meter which adopt the newest technique of personal computer and electronic currency IC card for purchasing electricity media and assisted by software and hardware technique of computer automation management for getting electricity fee.The meter has many functions such as electric energy measuring, load control and using electricity management etc. Its technique performance are completely conformed to the stipulated requirements of National Standard GB/T15283-94 international Standard IEC60521, it is used for measuring rated frequency 50Hz or 60Hz single phase AC active energy electric power consumption.Structure and features 1. The structure of microcomputer control board and photo-electricity sensor is designed. 2. It protects for overload input voltage, overload output IC card with code and data against false etc. 3. Voltage range in AC 154-287V is normal. 4. The data will preserved forever if power is interrupted. 5. The outline structure dimension and installation dimension and connection way is the same as ordinary meter.
