Three phase Multi-function electric meter
Overview:
Multifunction power meter sets ammeter, voltmeter, power meter, power factor meter and watt hour meter for an integrated monitoring meter. RS485 communication interface connects the meter to the monitoring center's computer network, which is suited to China's mining industry, civil construction, building automation and other modern distribution systems for a high-performance automation meter.
The meter is dedicated to the 50/60Hz power supply system integrated acquisition parameters. It can measure and display the three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, active energy (cumulative) and reactive energy (cumulative). Electric energy value only can be used as the internal two-level measurement assessment and accounting, but is not be used for valuation measure and paying.
Standard configuration:
1. The meter measures high or low voltage three-phase current, three-phase voltage, active power, reactive power, power factor, frequency, active power and reactive power on power grid.
2. Standard CT, PT or voltage signal directly inputs.
3. Wide range of AC and DC common power AC/DC80-265V or AC 220V.
4. Three rows of LED digital time display. All meter parameters can be set through the display panel buttons.
Note: The dimension of the meter is: 72mm * 72mm, Hole size is 67mm * 67mm.
Optional Configuration:
1. Having RS-485 communication interface (optically isolated), ModBus RTU communication protocol.
2.4 way switch remote signal inputs
3.4 way relay remote control outputs
4.1-4 way programmable analog outputs, DC4-20mA DC 0-5V.
5.1-way or 2-way power pulse outputs.
Note: To select the auxiliary function according to the requirement of the design drawings.
