The PS151 power supply module is in MicroPC format and is optimised for use in products designed to operate:
-in unattended systems in hard-to-reach areas;
- in systems with autonomous power supply from natural energy sources;
- in battery-powered systems on vehicles;
- in systems operating in extreme climatic conditions.
The intelligent power supply control system performs the following functions:
-controlling a watchdog timer that cuts power to the system in the event of a hang-up;
- ambient temperature monitoring and control of heater and fan channels in programmable temperature ranges from minus 50 ºC;
-logging of system events with time and date reference;
-automatic transition to a backup power supply channel;
-switching on/off the system by schedule;
-function of "guarding" the system, which is in a switched-off state.
