This “Dual source Energy Meter” is specially designed for 3 Phase energy measurement application where Dual sources of AC power supply are available. The meter can be directly connected up to 60 amperes load without external CT. Through three relays included in the product, it provides facilities to disconnect user load in the event of a user exceeding preset KW or current assigned for utilities and DG.
“Prepaid” monitoring and control functions can be accomplished through PC based special “ energy measurement” software thus providing a versatile and robust “ Prepaid Metering Systems. The system allows management of electrical power consumption, prepayments, billing, management of incidental expenses (Maintenance etc) and finally, total financial transactions in a housing/office complex.
