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.

3-Phase Energy and Power Disturbance Analyzer PowerVisa
The 3-phase power and mains disturbance analyzer MAVOWATT 30 fulfills the standards EN50160, EN61000-4-7 and EN61000-4-15 which are relevant for mains quality measurement, as well as EN61000-4-30 which specifies measuring procedures for voltage quality. The class A device simultaneously monitors RMS values, harmonics, flicker and transients down to a time range of approximately 80 µs.
The MAVOWATT 30 has 8 measuring channels: 4 for voltage and 4 for current. The measuring configuration and the type of electrical circuit is selected automatically based upon detected measured quantities. The type of utilized monitoring with automatic limit value definition is easy to select.
The instrument can be operated intuitively with the help of icons which appear at the color touch-screen. Selection can be made in the english / european language version amongst Englisch, French, Finish, German, Italian, Polish, Spanish and Swedish. With the english / asian language version you can choose between English, Chinese (simple & traditional), Japanese, Korean and Thai.
