SmartGen丨Application of Three Power Automatic Switching System

With the rapid development of industry, people have higher and higher requirements for power supply reliability. In some important occasions, dual-power switching cannot meet the requirements, so it is necessary that reliable switching between the three powers to ensure the power supply continuity. As the core control part of three-power switching, three-power ATS controller is indispensable and plays a vital role. In order to meet the switching scheme of different switches and applications, SmartGen has developed HAT832 and HAT833 three-power ATS controller to meet the market demand.

HAT832 is used for Three Power switching system consisting of two ATS switches, which can be applied to Mains-Mains-Gen, Mains-Gen-Gen and other system types.

1. 
   Can be used for various PC-level switches;
2. Collect and display 3-way 3-phase voltage, frequency and phase sequence;
3. Collect and display load active power, reactive power, apparent power, power factor and current;
4. S1/S2/S3 priority arbitrary setting;
5. Power system type can set as Mains-Mains-Mains, Mains-Mains-Gen, Mains-Gen-Gen;
6. Voltage transformer ratio function;
7. Black box function, which can cycle record 5 pieces of log and each log contains 60 groups of data including switch status detailed data of 50s before and 10s after switchover;
8. Can control two gensets to realize cycle run, master-slave run and balanced run;
9. Genset scheduled run/scheduled not run function that can set as run once a day/week/month.

1. 
   HAT833 is used for Three Power switching system consisting of three ACB switches
   Collect and display 3-way 3-phase voltage, frequency and phase sequence;
2. Collect and display load active power, reactive power, apparent power, power factor and current;S1/S2/S3 priority arbitrary setting;
3. S1/S2/S3 master input, highest switching priority when input port is active;
4. Input ports forced manual mode and auto mode;
5. Auto transfer/restore input, auto transfer/restore when active, auto transfer, non-restore when inactive;
6. Elevator control output, output before load outage or switch transfer, is used to control the running elevator to stop at the nearest floor until the switch transfer is completed;
7. Closed output of 3-way ACB switches;Switch is transferring, output during the switch transfer process;
8. Voltage transformer ratio function.
