Product Characteristic

1、WIFI connection technology
Built-in smart WIFI connection technology, through a smartphone or wireless router, any network, reliable connection to the cloud server, when there is no WIFI and mobile network, automatically save all the data within the module, once connected to the external network automatically update the data to the cloud server;Has advanced self health check function, the controller through a more comprehensive generating set data, do data analysis for generating set, found potential problems in advance, to enhance the operation reliability of the unit, at the same time for the user to save the cost of professional and technical personnel, please check.

2, The black box record
Built-in black box recorder to record the failure before 18 seconds every second data, the data through mobile phones or WIFI uploaded to the cloud Service, realize remote fault diagnosis;With functions of battery performance testing, by examining the starting motor in generator starting moment, the fall of battery voltage, and the standby unit when the battery voltage, calculate the aging rate of the battery;
3, power generation data record function
For each process of generating a record store, contains the boot time, downtime, power generation time, generating electricity.Can record recently 6000 power, as an effective basis for power generation cost accounting;Also has the excitation voltage detection and electrically adjustable output voltage detection, provide more data for remote fault diagnosis;Fault record function: can record the recent article 600 fault record, controller failure is detected instant generator all running data and save the record to the Flash memory, can query on the screen, can also be uploaded to the computers and mobile phones.

4、The control protection function
To realize automatic diesel and gas generator starting/stopping, close/brake switch (ATS) and perfect fault display protection function, when multiple warning, warning column will display them in turn, facilitate analysis reason;Mains with over voltage, under voltage, frequency, frequency, phase and reverse phase sequence warning function, power generation has overvoltage, undervoltage, over frequency, low frequency, over current, lack of phase, reverse phase sequence warning and stop protection function;All outlet for relay output, the output and mainly adopts 16 a relay output, at the same time there are three passive relay output, more convenient for complex applications.
