1, AC sampling, the terminal has its own high-precision power metering chip, which can accurately measure the active and reactive power of the terminal itself, and can accurately reflect the various instantaneous data of the terminal locally.

2、Automatic meter reading, the terminal provides 2 RS485 interfaces, one for meter reading and the other for cascading.

3, pulse acquisition, the terminal provides 2 to 6-way remote signal/pulse input interface (optional, configurable), which can realize the acquisition of pulse data with different pulse widths.

4、Load monitoring and control, real-time monitoring of user voltage and current, disconnection and other information, support for local power and electricity control, support for direct remote control from afar.

(5) The terminal can take the initiative to report the opening of metering box, voltage, current and other abnormal events, as well as parameter change events.

(6) data storage, the terminal has a 64 MB high-capacity memory FLASH, freeze data saved at regular intervals, reducing the number of times FLASH is written. After power failure, all data are automatically saved except real-time data, and the saving time is more than 10 years.

(7) communication function, support for wireless GPRS/CDMA communication support UDP, TCP data communication, no need to network, always online, and has a local maintenance interface

(8) with power quality monitoring, task active reporting, parameter setting and query, timing functions

(9) Remote upgrade function, modularized segmentation upgrade and leakage points to make up for the upgrade, the upgrade program self-diagnosis, and can be switched back to the original program running.

(10) Fee-control function sends control commands to the terminal through the master station, and the terminal encrypts and decrypts the data to realize the control setting parameters.

(11) The terminal has a hardware security module approved by the State Cryptography Administration to realize data encryption and decryption functions. The hardware security module supports symmetric key algorithm and asymmetric key algorithm. The key algorithm complies with the relevant policies of the State Cryptography Administration, and the symmetric key algorithm is recommended to use the SM1 algorithm.
