LUNA GSM Meter Remote Management and Disconnect Unit is designed for use with current three phase active or active-reactive meters where remote management and remote disconnect and re-connect of power are needed. Using the optical serial data port or the RS485 port on the meter, this unit will collect comprehensive energy and meter status data periodically or on demand read-out the meter instantaneously. The information is relayed to the distribution company for analysis, if necessary power can be remotely switched off or on via a computer terminal or with a schedule. The disconnect unit can switch maximum of 120A load for each phase. The two way GSM communication allows utility companies to reach the meter and disconnect the power at any times. Since no new meter is necessary this unit allows easy modification to existing meters and as a result reduces the cost of AMR and disconnect investments for utility companies. With this unit it is also possible to realize a prepaid meter subscriber system with existing installed electricity meters where after reaching the prepaid limit the energy of the user can be easily disconnected.
