DTS1777-1 three-phase electronic carrier watt-hour meter is the new intelligent meter adopting
an international advanced micro-chip which has the function of carrier communications,relay
control.With ADE7755 chip,high integration,high measurement accuracy,speed and small
power consumption, it meets the standard of GB/T 17215-2002(IEC61036),carrier perform
ance conform to the standard of DL/T698-1999 electrical industry,and RS485 communication
protocol meets industry standard of DL/T645-1997 reliable watt-hour Meter,easy in stallation,
which is particularly applicable to electric energy measurement and control of commercial
customers and industrial users.
