FKGA43 - ZTY666 type Load-control Management Terminal is based on the construction of state grid corporation power user electricity information acquisition system request, unifies design, development and field service experience in the electric power industry for many years, based on the embedded software and hardware platform design of a new generation of load control terminals.

The terminal has AC sampling, state acquisition, pulse signal gathering, load control function; it can exchange data by RS485 communication interface, and complete the data storage, processing and other functions; Uplink channel using GPRS communication interface, it can exchange data with master station management system.

Features:

• Uplink channel: support RJ45 Ethernet interface, RS485 or GPRS communication interface (optional). It can exchange data directly with master station management system.

• Downlink channel: support 1 road RS485 communication interface, the biggest can load only 8 multi-function watt-hour meter data acquisition.

•Local interface: 1 road RS485 communication interface, 1 road RS232 communication interface, 1 road infrared communication interface, 1 road USB interface.

• AC sampling function: active accuracy level: class 1, reactive accuracy level: class 2(only as assessment reference use).

• State acquisition quantity function: with 5 roads state acquisition quantity, among them 1 road as access point to use, state input for passive open/close contact input.

• Pulse quantity acquisition function: mark with two way pulse acquisition, can receive meter output pulse, and according to the meter pulse constant Kp (imp/kWh or imp/kvarh), CT variable ratio, PT variable ratio calculation 1 min average power, and record the current day and month maximum power and time.

•Field maintenance function: It can set the parameters for maintenance work by RS485 communication interface, RS232 communication interface or infrared communication interface, also can copy and read data in site.

•Data acquisition function: it can copy and storage the meter data according to the end of the meter reading or timing acquisition time interval by RS485.

• Data management function: can save 31 days frozen data, 12 month freezing data, 12 ti20130111133503_1.pdf meter reading, frozen data, recently the curve of 31 days freezing data.

• Control function: with power fixed value control and electric energy control function, and with 5 road control output, among them 1 road for alarm output; Control relay output support two connection methods of normally closed /open.

•Power quality monitoring function: voltage limit, power factor the limit statistical, and other functions.

• Metering equipment monitoring function: monitoring record watt-hour meter running status, including meter parameters change, meter out-of-tolerance time, meter fault information, power descend, out-of-tolerance, meter fly away, and meter stop running and etc functions.

• Support remote or local online upgrade function: It supports remote upgrade breakpoint continuingly way, if a program upgrade is not successful, the concentrator can be made according to the original procedures operation; Also can use the U dish to backup local program updates, program, parameter setting, parameter.
