electronic single phase meter,active energy metering, RS-485 remote interface for AMR,electric larceny-proof functions.

intelligent single phase watt-hour meter:

1.advanced integrated circuits & surface mounted technology(SMT),accurate measureing single-phase AC active electrical power.2.wide-range,high-accuracy,long-life,no need to adjust & maintenance even if longtime working.3.electric larceny-proof functions:reverse active electrical power is reckoned in positive active electrical power.4.the max. powerload can be set, LED will caution when it reach the max power prescribed.If it exceed the max. power prescribed for 5 minutes,power will be cutted off,5 minutes later the power come back.5.three-ply data back-up,data can be retained over 10 years after power off.6.multi-rate function: support 4 rate phase.7.RS-485 remote interface for AMR.
