Product Description
Single Phase Power Line Carrier Electronic Meter
【General Introduction】
Adopting special large-scale integrated circuit and manufactured with advanced SMT process ,it is featured with reliable function, high precision, high overload and low power consumption. And its standard infrared communication port and RS5 communication can realize functions of local meter reading ,setting, clock setting and period program etc. The energy data are transferred via low voltage power line to remote concentrated meter reading system. It is low cost, reliable and safe for rural customers.
【Functions and Introduction】
* Power line carrier communication through software frequency extension ensures precision and reliable of data reading.
* Concentrated management makes terminals relay with each other automatically, thus prolongs communication distance.
* Precise measurement of active energy, and correct free for long term.
* Automatic Meter Reading System enables the remote reading and control.
* To record bi-directional energy cumulatively, prevent reversal tamper.
* Remote control of meter power for on or off possible.
* Display: mechanical register.
