-in unattended systems in hard-to-reach areas;
- in systems with autonomous power supply from solar panels;
- in battery-powered systems on vehicles;
- in systems operating in extreme climatic conditions.
The intelligent power supply control system performs the following functions:
-monitoring ambient temperature and controlling heater and fan channels in programmable temperature ranges from minus 50 0C;
-logging of system events with time and date stamping;
-controlling the watchdog timer that switches off the system power supply in case of hang-up;
-switching the system on/off by schedule;
- "guard" function of the system, which is in a switched-off state.
