 Single-phase Four-wire Electronic Multi-rate Prepaid Carrier-wave Smart Meter Model DTSFYI846 |
|
Single-phase four-wire electronic multi-rate prepaid carrier-wave Smart Meter Model DTSFYI846 is a novel intelligent Smart Meter developed and
manufactured by us by using the world's advanced microchip technology. The meter uses micro-processor of PL3000 series as the core and has carrier-wave
communication and relay control functions; for measurement of electric energy, measuring chip ADE7752 is used; the meter has the characteristics of high integration,
high accuracy of measurement, high speed, low power consumption, and rich communication.
The multi-rate prepaid carrier-wave Smart Meter adopts intelligent, safe and reliable CPU card in which 3DES coded calculation is used; prepayment is
made to purchase electricity so the meter has the function for prepay. Alarm for amount configuration, alarm at fire and overdue power cut-off. It's possible to set up
parameters from handheld infrared reader in conjunction with real-time monitoring, thus making it easy for the user to check and service.
