EQUS

Multipurpose electricity meter for three-phase four-wire networks, with extended functionality. It allows direct measurement of active and reactive energy in multi-rate prepayment metering mode or in a fully autonomous credit mode. Interchangeable communication modules and a built-in contactor make the device a perfect founda­tion for Smart Metering systems.

• Bidirectional and reverse measurement of active and reactive energy
• Measurement of power grid parameters: effective current and voltage, frequency, power factor
• Measurement of instantaneous power and maximum power
• Load profile logging
• Built-in contactor which allows disconnection of current circuits
• Operating mode: prepayment, credit or switched prepayment-credit
• Advanced prepayment functions
• Manual or automatic ending of a billing period
• Memory of at least 21 billing periods data
• Real-time clock managing two switchable complex calendars
• Calendars supporting 16 time zones and allowing to define any number of special days and permanent holidays, and 240 movable holidays
• Current and power limiting features
• Event logging
• Optical port and built-in communication port: serial (RS-485 or RS-232), M-Bus slave, M-Bus concentrator
• Removable communication module: PLC, GSM, RS-232/RS-485, LAN, SRD radio or other
• TV remote control via infrared port
• LCD display
• Measurement data can be read from the display (and by optical connection if powered by a replaceable AA 3.6 V battery) in the event of power failure
