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-definition 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 find 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.

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 flash RAM for data storage, it's recording the specified
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.

2
Power quality event logging
AFM-8A series in the voltage sag, swell and over current events occur, will record the
time of the incident and the trigger conditions. It's up to 50,000 records of power quality
events.
Waveform records
AFM-8A series can record 8 groups of each phase voltage and current waveform data,
each cycle has 64 points sampling data of the record, the meter can record before and
after the 8 cycle waveform data from trigger conditions establish. The trigger conditions
can be setting by user, it's provided the data for power quality analyze.
1.2 AFM-8A series product features
Multi-function, high precision
AFM-8A multifunction meter series has a powerful data collection and processing ability,
can measure many power parameters, and demand calculation, harmonic analysis,
maximum / minimum values, event alarm, energy accumulation, data logging , TOU
function, power quality event logging and waveform recording.
Voltage and current measurement accuracy is 0.1%, power is 0.25% and energy is 0.5%.
Compact design, easy installation
The dimensions of the AFM-8A series conform to the IEC standard 92mm DIN square
shape, and thickness only 82mm. Installation by self-locking buckles without screws,
installation or removal are very convenient.
Intuitive display, easy to learn and use
3.5-inch large screen, high-brightness LCD display, the screen clear and the content
intuitive, easy to learn and use. All measurement data can be easily read through the panel
keys operation, the parameters can be set by the panel keys, also can be written by the
communication. The parameters setting and accumulated values are stored in the FRAM,
even if the power down is not lost. LCD brightness can be adjusted, and standby screen
brightness also can be set, allowing you to use in different environments.
Wiring flexible and convenient
Whether the system is high or low voltage, and whether it is single-phase or three-phase
, you can choose the appropriate wiring to meter connection. AFM-8A series support
multiple wiring method, can cover all the power system applications.
Safety, high reliability
AFM-8A series with multiple isolation and anti-interference design, can operating in high-
interference environment. The meter also approved by CE certification and IEC standards
of EMC testing.
