1. Product Overview:
Three-phase multifunction power meter is a kind of multi-functional intelligent meter which has functions of ammeter, voltmeter, power meter, power factor meter, and watt-hour meter ,programmable measurement, displaying, digital communications and power energy pulse output. It is able to complete electricity measurement, power energy metering, data display, collection and transmission.
It has LED display and remote digital RS - 485 interface communication, and MODBUS - RTU communication protocol.RS485 communication interface connects the meter to the computer network monitoring center. It is a kind of high-performance automatic meter which is suitable for industrial and mining enterprises, civil construction, building automation and some other modern distribution system.
Multifunction power meter is used for comprehensive collection of 50/60Hz power supply system electrical parameters. It can measure and display three-phase voltage, three phase current, active power, reactive power, power factor, frequency, active power (accumulation) and the reactive power (accumulation). The electric energy value is only used for the enterprise internal secondary measurement assessment and accounting instead of valuation measurement and pay for access.
2. Standard Configuration:
2.1 The meter measures three-phase voltage, three phase current, active power, reactive power, power factor, frequency, active power (accumulation) and the reactive power (accumulation) on the electrical grid.
2.2 Standard CT, PT or voltage signals are input directly
2.3 A wide range of AC-DC general power AC/DC80-265V or AC 220V
2.4 It has LED display mode with wide angle of view and white background. All parameters can be set through the display panel buttons.
2.5 It has RS-485 communication interface (optically isolated), Mod Bus RTU communication protocol.
2.6 It uses the installation of disk opening with a hole.
