Features
- Upstream channel: Ethernet interface, GPRS communication interface (CDMA communication interface or fiber optic optional), can directly exchange data with the main station management system
- Downstream channel: 2 RS485 communication interfaces, standard configuration includes 8 (expandable) multifunctional energy meters for data acquisition
- Local interface: 1 RS232 communication interface, 1 infrared communication interface, 1 USB interface
- Communication sampling function: active power accuracy level 1 or 0.5s level, reactive power accuracy level 2 (used as a reference for assessment)
- State quantity acquisition function: equipped with 2 channels of state quantity acquisition and 1 channel of door contact. The state quantity input is a passive open/close switching contact input
- Pulse acquisition function: Equipped with two standard pulse acquisition channels, it can receive pulses output by the electric energy meter and calculate the 1-minute average power based on the pulse constant Kp (imp/kWh or imp/kvarh) of the electric energy meter, CT ratio, PT ratio, and record the maximum power value and occurrence time of the current day and month
- On site maintenance function: Maintenance work such as parameter setting and data query can be carried out through RS485 communication interface, RS232 communication interface or infrared communication interface
- Data collection function: It can collect and store electricity meter data through RS485 bus according to the set terminal meter reading day or timed collection time interval
- Data management function: can save 62 days of daily frozen data, 12 months of monthly frozen data, 31 meter reading days of frozen data, and the latest 30 days of curve frozen data
- Control function: It has power constant control and electric energy control functions, with standard configuration of 2 control outputs and 1 alarm output; Control relay output supports two wiring methods: normally open and normally closed
- Power quality monitoring function: It can perform functions such as voltage over limit, power factor over limit statistics, voltage qualification rate statistics, etc
- Monitoring function of electric energy metering equipment: monitoring and recording the operation status of the electric energy meter, including: changes in meter parameters, meter time deviation, meter fault information, decrease in energy indication, energy deviation, meter flight, meter stoppage, etc
- Support remote or local upgrade function: remotely upgrade programs through message and FTP methods, and support breakpoint resume function; Local program upgrade can be performed through USB flash drive or RS232
- Support remote communication module interchange function, hardware interface adopts State Grid standard specifications, supports plug and play of State Grid remote communication module
