1.1 AFM-8A series function introduction
Chapter 1. Meter overview
This is a powerful multifunction power meter
AFM-8A series is a powerful multifunction power meter, designed by high-speed
microprocessors and advanced signal processing technology. With three-phase power
measurement, display, power accumulation, power quality analysis, event logging, power
quality event logging, waveform record, TOU and network communications functions. 3.5-
inch high-de
fi
nition color TFT-LCD display provides a variety of data display, so you can
easily read the measurement data. User-friendly display and operation method allows
users to easily operate without having to
fi
nd the manual at any time.
Perfect choice for power SCADA system
AFM-8A series can be used as a stand alone meter, but also can be a power monitoring
system (SCADA) of the front-end devices, through a variety of communication interface for
remote data collection and control. The industry standard RS-485 communication interface
and MODBUS communication protocol, as well as Ethernet and MODBUS TCP / IP
protocol makes the network easy and convenient, is the perfect choice for SCADA system
integration.
Energy management
AFM-8A series can calculate bidirectional and four-quadrant active power and reactive
power accumulation, as well as the maximum / minimum value of the parameters and
demand calculation function, with the system software can help users to measurement the
energy consumption of each circuit loop and load trends.
Remote control
AFM-8A series is not only a measurement meter, in addition to includ DI, relay output
and AO interface, also can via second RS-485 port to connect expansion DIO modules, to
achieve
fl
exible I / O function, become a powerful discrete RTU system.
Analysis of power quality
AFM-8A series using digital signal processing technology, it can real-time measurement
the phase voltage and current total harmonic distortion (THD), individual harmonic (2-63rd),
voltage and current unbalance.
Data logging function
The AFM-8A series provides 4MB
fl
ash RAM for data storage, it's recording the speci
fi
ed
parameters on a regular time. Internal with high-precision real-time clock, each record with
a timestamp.
Time of use function(TOU)
The AFM-8A series has a powerful TOU function and up to 5 years of holiday setting
function. The user can be based on the local TOU price to settings for achieve energy
cumulative calculation.
